Description
Technical field
The present invention relates to Rural Water apparatus for treating river water pollution fields, and in particular to a kind of domestic sewage in rural areas discharge outlet changes
Make method.
Background technique
With the rapid development in rural area and the rapid raising of vast rural area living standards of the people and rural area livestock and poultry cultivation,
The development of the industries such as aquaculture and agricultural byproducts processing, the discharge amount of domestic sewage in rural areas are continuously increased, and seriously destroy agriculture
The ecological balance in village.Domestic sewage in rural areas mostlys come from excrement and its flushing water, bath sewage and kitchen during resident living
Generated sewage in room sewage and rural area dispersion breeding process.The characteristics of domestic sewage in rural areas water quality is N, P content is high, can
Biochemical is strong, less containing venomous injurants such as heavy metals, has each household discharge amount relatively fewer in discharge, variation water quality compared with
Greatly, emission point disperses, multi-point and wide-ranging, and collection is more difficult, and most rural area does not have the features such as sewage treatment system.Therefore rural area river
The discharge of sewage draining exit easily pollutes river.
In the prior art, Ecological Disposal is carried out to rural area river by the way of artificial swamp.Artificial swamp includes surface
Wet and current wetland is flowed, wherein current wetland is divided into horizontal flow artificial wetland and vertical current constructed wetland, with free water surface wetland phase
Than, horizontal flow artificial wetland hydraulic loading is high, and it is preferable to the removal effect of the pollutants such as BOD, COD, SS, heavy metal, and without evil
Smelly and mosquitos and flies multiplies, and is current using a kind of widest wetland form.But control is relative complex, and N, P removal effect are not as good as vertical
Direct current artificial swamp.Vertical-flow wetland be divided into it is lower to stream and two kinds of upward flow, it is lower relatively simple with its operation to stream vertical-flow wetland
Single more commonly used, sewage enters from surface water flow, flows through Wetland Substrate layer from top to bottom, is flowed out by bottom.Upward flow water flow side
To on the contrary.Since oxygen can be transferred into wet land system by Atmospheric Diffusion and plant, internal oxygenation is more abundant, is conducive to
The growth of aerobic microbiological and the progress of nitration reaction, nitrogen, phosphorus ligands effect are preferable.Therefore two kinds of wetlands can be integrated by designing one kind
Advantage, while convenient for construction, the bank protection structure high to sewage draining exit purification monitoring capacity has a very important significance.
