The method of sectional type comprehensive regulation city river sewage

Technical field

The present invention relates to a kind of method of administering city river sewage, relate in particular to a kind of method of sectional type comprehensive regulation city river sewage.

Background technology

Development along with city, population is more and more concentrated, the river course in many cities is polluted by sanitary sewage, and be difficult to recover by methods such as ecosystem planting floating bed plants, because of city river sewage degree serious, animals and plants all cannot survive, therefore only have after city river pollutes to a certain degree, sewage is evacuated to sewage works or is directly extracted into ground by pump, sewage is directly extracted into ground and just sewage has been changed to a place, and have a strong impact on underground water, to ground flora, be also serious destruction, and employing is drawn into the method for sewage work by pump, not only because sewage work is away from river course, cause the difficulty of pipeline laying, and power consumption is large, and some small and medium-sized cities or counties and districts do not have sewage work, cannot effectively administer the city inland river after polluting, for sewage is pumped to sewage work, publication number is CN 102505660 B, sewage-intercepting water-collecting well for river channel discloses and has utilized water conservancy automatically sewage to be drained to sewage work, there are several defects in it: 1, the size of water-in can not be controlled, can not be applicable to the river course that the height of water is large uses, 2, this sewage-intercepting water-collecting well for river channel also needs pipeline that sewage is drained to sewage work, and use cost is high, is difficult to popularize, 3, the sewage reclaiming enters the resource that sewage work takies sewage work, 4, the water of the standard that reaches after processing can not enter river course again.

Summary of the invention

The object of the present invention is to provide a kind of method of sectional type comprehensive regulation city river sewage, solved the defect existing in prior art, can not in river course, dispose of sewage, and can facilitate later maintenance, the river course that the improves severe contamination vegeto-animal problem of can not surviving.

The present invention is achieved in that and it is characterized in that method is:

1) 3-5 gate is set uniformly on river course according to the requirement of the length in river course and river water, gate quantity be take 1 or 2, downstream, river course can hold whole piece river water as principle;

2) close 1, downstream or a water reservoir of 2 gates formation, water reservoir can hold whole piece river sewage, on river course, other gates are opened, the sewage of upstream, river course is all drawn in the water reservoir in downstream, river course, adopt existing technique to process sanitary sewage, take that to reach animals and plants can self-sow be principle;

3) when the sewage in lower reservoir is processed, mud is cleared up in the river course of draining sewage; Mud whether is cleared up in river course or clearing times is determined water quality impact degree according to local mud;

4) close first gate of upstream and form the first water reservoir, new sanitary sewage is held at the first water reservoir, then open aft gate, by meeting the requirements of water quality after processing, enter river course; According to the whether throw out desilting by the mud in lower reservoir and after disposing of sewage of water quality requirement;

5) water quality after processing, in river course, is built floating bed on river course according to prior art, throws in a kind of or several of biologic detoxication agent and biological growth promoter in water body, and the growth of favourable aerobic bacteria, is convenient to by organism in natural means degradation water;

6) for the sewage in the first water reservoir, by prior art, sanitary sewage is processed, thereby reached the water quality requirement that animals and plants can self-sow; Then enter river course, the sewage that makes like this to enter river course is unlikely to pollute too serious, guarantees to reach by natural ecosystems the effect of pollution treatment.

Described gate is comprised of the identical baffle plate of polylith size, and the baffle plate formation of being convenient to remove on gate according to elevation of water surface discharges water.

Technique effect of the present invention is: 1, do not need other pipe laying that sewage is incorporated into sewage work, save cost of sewage disposal; 2, the water after processing can be got back to river course fast again, and by the organism in the method absorption river courses such as floating bed plant, can reach the later stage to carry out less sewage disposal or do not carry out sewage disposal; 3, sewage just carries out sewage disposal after entering river course, do not affect other water bodys in river course, effectively alleviate the pollution of sewage to river course, by sewage river course, within 1 year one, administer and at least can bring up to an improvement in 3 years, not only control expense reduces, and urban environment is better.
