Supplier of sewage treatment equipment for township hospitals——Process Description

After pre-treatment in the septic tank, domestic sewage is intercepted by coarse and fine grids and enters the regulating tank for water quality and quantity regulation. The regulating tank sewage is lifted to the integrated sewage treatment device for biochemical treatment by a lift pump, and then undergoes anoxic denitrification and aerobic treatmentMBRThe solid-liquid separation is carried out in the treatment and secondary sedimentation tank, and the effluent is then passed throughAFFAsymmetric fiber filtration system for filtration and anti catalytic disinfection treatment, meeting emission standards.

Supplier of sewage treatment equipment for township hospitals——Basic knowledge of equipment

1workmanship

A sewage treatment method consisting of a filling material and an aeration system immersed in sewage. Under aerobic conditions, the sewage comes into extensive contact with the biofilm on the surface of the filling material, purifying the sewage.

2filler

Refers to providing a place for microorganisms to inhabit and grow in sewage treatment, using solid media or carriers to fix microorganisms, and using suspended fillers and suspended fillers for smooth flow.

3biofilm

The pore like structure formed by microbial cells growing and reproducing on the surface of the filling material in the contact oxidation tank under the action of extracellular polymeric substances extending from the inside out.

4Water distribution device

The device refers to the uniform distribution of biological contact with the inlet water of the oxidation tank. When the amount of treated water is small, direct inflow method can be used; When dealing with a large amount of water, methods such as inlet weirs or inlet galleries can be used.

5aeration system

A system that uses only perforated pipes, aeration heads, or aeration hoses located at the bottom of the aeration tank to transport air through pipelines and transfer oxygen to wastewater.

6Aeration zone

The area in contact with the lower part of the packing layer in the oxidation tank, which can be used to arrange aeration devices.

7Packing layer

The area where the filling material is arranged in the middle of the contact oxidation tank is related to the thickness, properties, and inlet water quality of the filling material.

8Stable water layer

It refers to the water layer above the filling layer of the oxidation tank, which plays a role in stabilizing the effluent.

9Packing volume load

The amount of pollutants that can be accepted per cubic meter of filling material per day, including five-day biochemical oxygen demand volumetric load, digestion volumetric load, reverse digestion volumetric load, and so on.

10Surface hydraulic load

Refers to the daily amount of sewage that can be received per square meter of pool area.

11air-to-water ratio

The ratio of the volume of gas introduced per unit time to the volume of water introduced per unit time, usually an empirical value.

12preprocessing

When the incoming water quality cannot meet the biochemical requirements of the biological contact oxidation process, conventional treatment processes such as grids, dust and sand, and initial sedimentation are set up before the biological contact oxidation reaction tank.

Supplier of sewage treatment equipment for township hospitals——Advantages and characteristics of underground integrated sewage treatment technology

1Made of carbon steel spliced together, it is lightweight, easy to transport, convenient to install, corrosion-resistant, has a long service life, and has a very short construction period. Generally speaking, it takes one day to process200A ton of simple sewage treatment plant45Construction, debugging, and trial operation can be completed within days.

2Reasonable and compact structure, buried underground for thermal insulation, suitable for cold winter weather（-30(℃) can still operate normally and adapt to the vast climate environment in the north and south of China.

3It can be flexibly buried according to the surrounding terrain to integrate into the surrounding environment and reduce the footprint. For example: daily processing200A ton sewage treatment plant with a small footprint only requires100m2左右。

4The small-scale domestic sewage treatment equipment in the village realizes decentralized sewage treatment and is installed on-site at the sewage discharge point, saving a lot of pipeline investment. The model and installation method can be flexibly selected according to the sewage volume and geographical conditions, and can be used individually or in combination with multiple. For example, one400 m3/dIf the sewage treatment plant adopts artificial wetlands or artificial rapid infiltration sewage treatment technology, it cannot be treated separately and cannot be flexibly moved according to geographical location, requiring land acquisition1600 m2左右

Centralized sewage treatment requires significant investment in the pipeline network; And adoptingNLBProcess technology, different product models can be selected for on-site treatment at the sewage discharge point according to the size of the sewage volume. This project400 m3/dThe processing scale is divided into two parts200 m3/dThe sewage treatment station is located nearby for treatment, occupying a small area, with a single station area occupying as little as130 m2Flexible and adaptable, greatly saving pipeline investment.

5No pollution, low noise, no odor, reducing secondary pollution. Due to the process entering the endogenous metabolic stage of microorganisms, the sludge yield is low. The generated sludge has high mineralization degree, high stability, low odor, and small quantity. Generally, sludge pumps are used to extract it every year3-4After treatment, it can be used as an excellent organic fertilizer to reduce secondary pollution.

6High degree of automation, low energy consumption, few operation and management personnel, and low cost. For example, two in Huangshi Town200A ton of sewage treatment plant only requires1Simultaneous part-time supervision by personnel, with low operating costs per ton of water0.21Yuan.

7.High purification efficiency. After being treated by an integrated sewage treatment process,

All indicators of effluent can meet the "Pollutant Discharge Standards for Urban Sewage Treatment Plants"（GB18918-2002）Primary emissionsBStandard; If hollow fiber membrane fine filtration is added and then subjected to three-level deep treatment, the effluent can meet the "Water Quality Standards for Miscellaneous Water in Urban Sewage Recycling and Utilization"（GB/T18920-2002）And the "Water Quality Standards for Landscape Environment Water Use in Urban Sewage Recycling and Utilization"（GB/T18921-2002）To carry out regeneration and utilization; It can be matched with greening projects in real estate development to irrigate flowers, plants, and trees with water, achieving zero discharge of sewage in real estate development projects. can also

Fully utilize the effluent and arrange it into a beautiful landscape, forming a water treatment landscape that integrates streams, fountains, ponds, and fish ponds. This not only treats sewage but also beautifies the environment, satisfying people's desire to live by the water.
