Description

A kind of sewage treatment unit

Technical field

This utility model is related to sanitary sewage disposal field and in particular to a kind of sewage treatment unit.

Background technology

The sanitary sewage producing during human lives, is one of primary pollution source of water body, and it is dirty that it mainly includes lavatory Water and washing sanitary sewage etc..Everyone daily sanitary sewage amount discharged of cities and towns is about 150l～400l, its amount and living standard There is substantial connection.Large amount of organic is contained, such as cellulose, starch, saccharide and fat protein, mainly density in sanitary sewage Fat less than water；Also contain inorganic salt, such as chloride, sulfate, phosphate, bicarbonate and sodium, potassium, calcium, magnesium and few Heavy metal of amount etc..

At present, the sanitary sewage in China cities and towns takes traditional processing mode mostly, to by sanitary wastewater and wash water The sanitary sewage of composition is uniformly processed, and that is, after the collection of sewage collecting pipe network, unification is transported to sewage treatment plant and carries out Process, this processing mode has following defect: sewage treatment process facility and sewage network construction cost are high, and sewage exists simultaneously It is susceptible to when conveying in pipe network leak or block, especially rainy day, pollute environment, reduce people's quality of the life, and can Feces as vegetable fertilizer emit, waste of resource；Additionally, the mode focusing on is so that Water circulation must build pipe again Net or transported, increased the cost of reuse.

Utility model content

In view of the shortcomings of the prior art, this utility model provides a kind of sewage treatment unit, this apparatus structure Simply, processing cost low, reduce pollution, efficent use of resources, and process after sewage reach water purification standard, profit can be circulated With improving water utilization rate.

In order to achieve the above object, the technical scheme that this utility model is taken:

A kind of sewage treatment unit, including sanitary wastewater processing system and wash water processing system, described lavatory Sewage disposal system includes the anaerobic tank that sanitary wastewater manifold trunk is connected with sanitary wastewater manifold trunk, and described anaerobic tank is airtight Structure and which is provided with suction excrement mouth, described wash water processing system includes wash water manifold trunk and wash water manifold trunk The Organic substance processing pond connecting, the rear of described Organic substance processing pond connects inorganic matters processing component, described inorganic salt processing unit Part can be multistage stair-stepping dirt sand water channel, or for multiple by the interconnective deep clarifier-tank of delivery pipe, or set successively Put dirt sand water channel, multiple deep clarifier-tank, the plant for processing inorganic salt that described deep clarifier-tank includes setting gradually is net Change pond, the discharge pond for the sewage after processing the scavenging material clarifier-tank of beavy metal impurity, purifying for discharge.

As optimal technical scheme, in order to ensure that wash water puts, in each deep clarifier-tank, the ample time staying, with true Protect inorganic salt, heavy metal is fully absorbed by plant, adsorbing material respectively, effectively improves the clean-up effect of sanitary sewage, it is to avoid water Resource eutrophication and soil heavy metal pollution, described delivery pipe is by effusion meter control.

As optimal technical scheme, the phenomenon overflowed in order to avoid anaerobic tank overfill, thus polluting environment, affect people Quality of the life, described anaerobic tank is provided with volumeter.

Compared with prior art, this utility model has the advantages that

1st, pass through to arrange sanitary wastewater processing system and wash water processing system processes sanitary wastewater, washing dirt respectively Water, structure is simple, be easily achieved；Sanitary wastewater can effectively reduce pollution and improve resource utilization as fertilizer after extracting；Wash Wash sewage after multistep treatment, reach water purification standard, can be recycled, and adopt plant purification, processing cost is low, and improve The greening in cities and towns and there is ornamental performance.

2nd, delivery pipe is by effusion meter control, to guarantee that inorganic salt, heavy metal fully absorb by plant, adsorbing material respectively, Effectively improve the clean-up effect of sanitary sewage, it is to avoid water resource eutrophication and soil heavy metal pollution.

3rd, anaerobic tank is provided with volumeter, it is to avoid anaerobic tank overfill and the phenomenon overflowed occurs, and then pollute environment and shadow Ring people's quality of the life, improve the utilization rate that sanitary wastewater becomes fertilizer simultaneously.
