Large hospital sewage treatment equipment manufacturer price: starting from 30000 yuan, specific quotation price needs to consult customer service.

Analysis of sewage quality in large hospitals:

The sewage of large hospitals mainly comes from the wastewater discharged by patients in their daily lives, including some medical wastewater containing a large amount of Escherichia coli. The main ones are feces and washing wastewater. The hospital's domestic sewage contains a large amount of organic matter, such as cellulose, starch, carbohydrates, and lipoproteins; It also often contains pathogenic bacteria, viruses, and parasitic eggs; Inorganic salts such as chlorides, sulfates, phosphates, bicarbonates, and sodium, potassium, calcium, magnesium, etc. The overall characteristic is high nitrogen, sulfur, and phosphorus content, and under the action of anaerobic bacteria, it is prone to produce odorous substances.

Parameters of sewage treatment equipment in large hospitals:

Single set of equipment processing water volume: Q=5t/h

Inlet CODcr 150-250mg/L, outlet CODcr ≤ 60mg/L

Inlet BOD5100-200mg/L, outlet BOD5 ≤ 60mg/L

Inlet SS ≤ 250mg/L, outlet SS ≤ 50mg/L

Gas water ratio of contact oxidation tank: 12:1-15:1

Large scale hospital sewage treatment equipment technology:

1. The combination of hydrolysis acidification and biological contact oxidation method effectively improves the treatment effect, and the treated water can meet the national discharge standards.

2. The generated sludge is minimal, and the sludge generated at each stage can be recycled and digested, with regular extraction of the final sludge.

3. The process flow can be organically combined and can be buried underground. On the surface, parking lots or green lawns can be built to decorate the surrounding environment.

4. This complete set of equipment has high automation, with automatic operation of equipment such as fans and pumps in the system, reducing operational workload. This equipment adopts effective measures to reduce noise and odors, and has no impact on the surrounding environment.

5. After deep treatment, the effluent can be reused.

Underground large-scale hospital integrated domestic sewage treatment equipment for disposal of equipment treatment water volume under different conditions (m3/h)

Characteristics of sewage treatment equipment in Zhengyuan Environmental Protection Large Hospital:

1. This device is capable of treating comprehensive wastewater from domestic systems and similar organic wastewater.

2. The secondary biological contact oxidation treatment process of the equipment adopts the contact oxidation process, which has a smaller volume than activated sludge, good adaptability to water quality, stable effluent water quality, and no sludge expansion.

3. The equipment can be buried below the ground surface, which can be used as green or square land. Therefore, the equipment does not occupy the surface area, does not require building, and does not require heating and insulation.

4. The complete set of equipment is simple to construct and easy to operate. All mechanical equipment is automatically controlled, and all devices are located underground.

5. The entire processing equipment generally does not require dedicated management, only timely maintenance and upkeep of the equipment.

6. No need to compress the container. Equipment such as air compressors and circulation pumps greatly reduce investment costs.

7. If the device is used in cold regions, the inspection hole can be raised to bury the device under frozen soil.

8. The integrated buried domestic sewage treatment equipment in large hospitals consists of two levels of tanks. The first level is a reinforced concrete structure with a larger burial depth, while the other group is a steel structure with a shallower burial depth. After the equipment is coated with paint, its anti-corrosion life can be extended for a long time.

Process of large hospital sewage treatment equipment:

1. The secondary biological contact oxidation treatment process of hospital sewage treatment equipment adopts push flow biological contact oxidation, which has a better treatment effect than fully mixed or two-stage series fully mixed biological contact oxidation tanks. And it has a smaller volume than activated sludge tanks, strong adaptability to water quality, good shock load resistance, stable effluent quality, and will not cause sludge expansion. A new type of composite packing material is used in the pool, which has a large specific surface area and is prone to microbial biofilm formation and demolding. Under the same organic load conditions, it has a high removal rate of organic matter and can improve the solubility of oxygen in the air in water.

2. The entire equipment processing system is equipped with a fully automatic electrical control system and equipment fault alarm system, which operates safely and reliably. Generally, there is no need for dedicated personnel to manage it, and only timely maintenance and upkeep of the equipment is required.

3. The biochemical tank adopts the biological contact oxidation method, which has a relatively low volume load of the filling material, and the microorganisms are in the self oxidation stage, resulting in low sludge production. It only takes more than three months (90 days) to discharge the sludge (using a manure truck to suction or dehydrate it into a sludge cake for external transportation).

Zhengyuan Environmental Protection Technology Co., Ltd. has designed a large-scale hospital wastewater treatment equipment using SBR process according to environmental requirements. The main advantages are: simple process, flexible control, and reduced investment. The equipment is refined, easy to maintain, and saves maintenance costs.
