Solution for outpatient sewage treatment in community hospitals:

The sewage from community hospitals contains some special pollutants, such as drugs, disinfectants, diagnostic agents, cleaning agents, and a large number of pathogenic microorganisms, parasite eggs and various viruses, such as scar eggs, hepatitis viruses, tuberculosis and dysentery bacteria. If not dealt with in a timely manner, it will cause serious pollution. Today we will briefly discuss the working principle of hospital sewage treatment equipment. The treatment of hospital sewage must meet the standards. The three main processes are: primary treatment, secondary treatment, and simple biochemical treatment.

The entire community sewage treatment equipment consists of sewage pumps, metering devices, dosing tanks, reaction tanks, air flotation tanks, air flotation systems, sand filters, activated carbon adsorption towers, and electrical control systems, which can be combined and used on the same basis of 10t/h. When it exceeds 10t/h, it can be assembled as a single component on site for easy transportation. Can be designed according to user requirements (non-standard). After adjusting the entire device to normal operation, it can run automatically and is easy to operate.

Small community hospital sewage treatment equipment technology:

1. Infectious disease hospitals must adopt secondary treatment and conduct pre disinfection treatment.

If the sewage from hospitals at or above the county level is discharged into natural water bodies, secondary treatment must be adopted.

3. The treated water is discharged into the urban sewer system (there is a secondary sewage treatment plant downstream). The comprehensive hospital recommends using secondary treatment, and the use of primary treatment techniques must enhance the treatment effect.

For small comprehensive hospitals in economically underdeveloped areas, simple biochemical therapy can be used as a transitional treatment measure when conditions are not met, and then gradually achieve secondary or primary treatment to improve treatment effectiveness.

Introduction to the functions of each part of the sewage treatment equipment in community hospitals:

1. Septic tank function:

Every residential building with sanitation facilities must discharge sewage, which contains various organic or inorganic substances such as excrement, silt, and tissues. The function of septic tank equipment is to intercept and settle these substances, and then clean them regularly. The supernatant of the sewage is discharged into the downstream pipeline network.

Septic tanks have been widely used in the pretreatment of hospital sewage disinfection. In order to improve the effluent quality and disinfection effect of septic tanks, domestic sewage and medical flushing water should not be discharged into septic tanks, but should be filtered and directly discharged into sewage treatment plants. Septic tanks used for hospital sewage disinfection are 2-3 times larger than general domestic sewage treatment septic tanks. Relevant regulations also stipulate that the volume of septic tanks should be calculated based on the retention time of sewage in the tank, which should not be less than 36 hours, and the sludge removal cycle should be appropriately selected.

2. Mechanical grille:

Mechanical grid cleaning machineIt is an important device that can intercept larger suspended particles as well as shredded and condensed soft materials (such as paper scraps, rags, or food residues), and prevent blockages in water pumps or pipelines. A grille should be installed in front of the sewage treatment system or water pump.

3. Function of sedimentation tank:

The function of a sedimentation tank is to balance water and its unevenness. According to the survey, when the hospital experiences peak load, the maximum hourly water consumption can reach 1/7 of the daily water consumption. Moreover, during periods of high water consumption, there is often a high concentration of pollution in community sewage. It can be seen that setting up sedimentation tanks can greatly reduce the capacity and power consumption of treatment equipment. Therefore, community hospitals should establish a sedimentation tank for sewage treatment, which should operate continuously, and its effective capacity should be calculated based on 30-40% of the daily treated water volume. In intermittent operation, the effective quantity should be calculated according to the equipment process operation cycle.

The sedimentation tank should be pre aerated, with an aeration rate of not less than 0.6 and m3/(m3 · h). The water in the pool should be stirred and oxygenated to prevent the suspension and sedimentation of impurities and improve water quality. In addition, the collection tanks of intermediate and above hospitals should be divided into two groups, with each group allocated 50% of the water.

4. Function of biological aeration tank:

Biochemical treatment is the use of microbial life processes to convert organic matter in wastewater into simple inorganic forms. It is divided into three types based on oxygen supply: biochemical treatment, anaerobic biological treatment, and aerobic biological treatment. In the aerobic biological treatment project of sewage, it is necessary to continuously artificially aerate the mixed liquid to provide the oxygen required by microorganisms, and stir and mix it to make it a sewage treatment plant. Activated sludge is in a suspended state, which can prevent sedimentation and allow sufficient contact between oxygen and the mixture to promote the degradation of organic matter.

5. Disinfection contact pool function:

The disinfection contact tank is one of the main structures of hospital sewage treatment facilities. Its main function is to add disinfectant to ensure sufficient contact between sewage and disinfectant, ensuring the required disinfection time and achieving disinfection effect. The commonly used chlorine disinfection contact tanks have the following requirements: the volume of the disinfection contact tank equipment should take into account factors such as the volume of drinking water, contact time, sludge deposition, etc. The exposure time of sewage in infectious disease hospitals should not be less than 1.5 hours, and the exposure time of sewage should not be less than 1.5 hours. Generally, hospitals should not be less than 1.0 hour. When the treatment process is gravity self discharge and the discharge volume is large, the discharge volume should be calculated based on the discharge volume. When using a sewage pump for lifting, the amount of sewage should be calculated based on the actual hourly displacement of the pump. The effective volume of the continuous disinfection contact tank is the sum of the sewage volume and the sludge volume, and the intermittent disinfection type is the disinfection type. The total effective volume of the contact tank should be determined according to the work shift and disinfection time, and the volume of the adjustment tank should generally be 1/2. The contact disinfection pool is generally divided into two compartments, with each compartment having a volume of half of the total volume. The aspect ratio of the water flow channel should not exceed 1:1.2, and the length to width ratio should not be less than 20:1. A sampling port should be installed at the outlet of the contact tank.

Characteristics of sewage treatment equipment in community outpatient hospitals:

The surface above equipment buried underground can be used for greening or other land without the need for building houses, heating, and insulation.

2. The secondary biological contact oxidation treatment equipment adopts a push flow biological contact oxidation process, which has a better treatment effect than fully mixed or two-stage series fully mixed biological contact oxidation tanks. Compared with activated sludge tanks, it has a smaller volume, stronger adaptability to water quality, better resistance to shock loads, stable water quality, and no sludge expansion. The pool adopts a new type of elastic three-dimensional packing material with a large specific surface area, making it easy for microorganisms to hang. Under the same organic load, the removal rate of organic matter is high, which can improve the solubility of oxygen in water.

3. The biochemical pool equipment adopts the biological contact oxidation method. The volume load of the filler is relatively low, and microorganisms are in the self oxidation stage, resulting in less mud production.

4. In addition to conventional ventilation, the deodorization method for hospital sewage treatment equipment also includes soil deodorization measures.

5. The entire community sewage treatment equipment treatment system is equipped with an automatic electrical control system and equipment fault alarm system, ensuring safe and reliable operation. Under normal circumstances, there is no need for special personnel to manage, but only timely maintenance and upkeep of equipment.

6. The equipment is capable of processing comprehensive wastewater and similar organic wastewater from domestic systems;

7. The community sewage treatment equipment is made of glass fiber reinforced plastic, stainless steel structure, corrosion resistance, aging resistance and other excellent characteristics, with a service life of more than 50 years;

8. The entire community's sewage treatment equipment has a simple structure and is easy to operate. All mechanical equipment is automatically controlled and can be installed underground.
