The treatment of domestic sewage in residential areas, villa communities, villages, and towns.

Stations, airports, seaports, and ship docks.

Factories, mines, troops, tourist attractions, scenic spots.

The treatment of wastewater from aquatic processing plants, livestock processing plants, fresh milk processing plants, and other production facilities.

Various industrial organic wastewater similar to domestic sewage.

The manufacturer's price for residential sewage treatment equipment starts at 15000 yuan. Please consult customer service for specific pricing.

Parameters of sewage treatment equipment in residential areas:

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

Residential 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.

Integrated domestic sewage treatment equipment for buried residential areas with different treatment water volumes under different conditions (m3/h)

Characteristics of sewage treatment equipment in Zhengyuan Environmental Protection Community:

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 the community consists of secondary tanks. The first stage is a reinforced concrete structure with a relatively deep burial depth, and the other group is a steel structure with a relatively shallow burial depth. After the equipment is coated with paint, its anti-corrosion life can be extended for a long time.

Process of residential sewage treatment equipment:

The design of this equipment is mainly for the treatment of domestic sewage and similar industrial organic sewage. Its main treatment method is the contact oxidation method, which is currently a mature biochemical treatment technology. The water quality design parameters are also calculated according to the general domestic sewage water quality design, with an inlet level of BOD5200mg/L. It consists of four parts: (1) a sedimentation tank; (2) Primary contact oxidation tank; (3) Secondary contact oxidation tank; (4) Secondary sedimentation tank; (5) Disinfection pool; (6) Composed of fan room and fans.

The following are discussed separately:

(1) The sewage in the regulating tank of the primary sedimentation tank is pumped into the primary sedimentation tank by the sewage pump, and some larger particles of pollutants are settled down. Lift the sludge to the sludge tank.

(2) Contact oxidation tank: The sewage in the first stage sedimentation tank flows into the contact oxidation tank for biochemical treatment. The contact oxidation tank is divided into two stages, with a total residence time of 7 hours. The filling material is a novel elastic filling material, which is easy to film and does not block. The gas water ratio of the oxidation tank is around 20:1.

(3) Secondary sedimentation tank: The biochemical wastewater flows to the secondary sedimentation tank, which adopts vertical flow sedimentation with an upward flow rate of 0.1-0.15 mm/s, and the sludge is lifted to the sewage level.

(4) Disinfection pool and disinfection device: The disinfection pool follows the "TJ14-74" standard, and the water stays here for 45 minutes. The disinfection method adopts the contact dissolution of solid chlorine tablets. The disinfection device can continuously change the dosage according to the size of the water output, achieving the goal of adding more water and more medicine, and adding less water and less medicine.

(5) Fan room and fan: The fan room is located above the clean water tank. The fan adopts two three blade Roots blowers, which can automatically alternate operation and can be adjusted for 0-12 hours. The operating life of a single fan is about 30000 hours. The air inlet has a muffler, so the noise during operation is low.
