Description
Technical field
The present invention relates to sewage treatment area, more particularly to a kind of pretreatment system of river sewage.
Background technology
River is the important component of ground water system, can not only supply domestic water, and also ensure industrial water,
Fire demand water and green area irrigation etc..For river in addition to the recharge of ground water, rainwater supply is its important sources, is dissolved in early-stage rainwater
The pollution gas such as a large amount of sour gas, vehicle exhaust, plant gas in air, behind ground of landing, and due to washing away room
Face, road surface etc., substantial amounts of polluter is carried in early-stage rainwater.In addition, the sewage such as sanitary wastewater, industrial and agricultural production waste water without
Processing directly remittance river in, the soluble pollutants such as suspension (rubbish, oil slick etc.), N, P, heavy metal in sewage and other
Organic Pollutants will be produced to the water quality of river and had a strong impact on.
Such as：The Chinese invention patent of Application No. 201510548086.6 (application publication number is the A of CN 105152472)
《A kind of rainwater enters the osmosis type eco-embankment of river contamination control》A kind of eco-embankment is disclosed, it includes building along bank of river
Artificial permeation's system, artificial permeation's system includes the osmotic cell being connected with catch-basin by water inlet pipe, in osmotic cell oneself
Collection water layer, supporting layer and filter layer are disposed with down, collects in water layer and is provided with the drainpipe for being connected to river course, by runoff rain
Into filter layer, rainwater flows from top to bottom to be purified the uniform dosing of water by filtering layer, supporting layer, passes through the collection water layer of bottom
After collection, river is drained into.Biological embankment in above-mentioned patent can be handled into river rainwater non-point pollution, but not to a certain extent
It is adapted to enter river waste water to other and handle, especially sanitary sewage, in addition, only passing through the simple physics chemical action of osmotic cell
Sewage is handled, clean-up effect is bad, also, the landscape effect of the eco-embankment is bad.
