Description
Technical field
The invention belongs to a kind of field of sewage treatment, and in particular to electricity production eversion type current artificial swamp sewage purification in a kind of
System.
Background technology
With the fast development of social economy, China's water environment situation is increasingly serious.The great number of issues that water pollution triggers
It makes people worried, the renovation of polluted-water has all been carried out in various regions in succession.In the case, city point-source pollution improvement achieves
Certain achievement, but in the vast rural areas, water pollution problem but highlights further.Countryside sewage treating has become water ring instantly
The most important thing of border cause.
Rural pollution has the characteristics that have a large capacity and a wide range, dispersiveness, the pollution control and operation of special heterogeneity, in addition rural area
Maintenance technology weak is badly in need of investment and operating cost is low, at high treating effect, stable, the simple water of maintenance management
Reason technology.
The one kind of artificial swamp as ecological restoring method compared with traditional secondary biochemical treatment, has and builds and transport
Row expense is low, safeguards the advantages that simple, is suitable at not high technology management level, cities and towns of scale is smaller or rural sewage
Reason.However engineering practice find, for ensure water in carbon, nitrogen removal, it usually needs larger area come complete organic carbon removal and
Nitrification, denitrification process, the engineering for limiting the technology are promoted.
For this problem, the present invention is by producing electricity eversion type current constructed wetland sewage purification system in one kind, by dirt
The compact control of organic carbon metablism, Microbial denitrogenation and adsorption coprecipitation dephosphorization process in water in same artificial swamp,
And realize efficiently removal.The system has reduced investment, operational management convenient, beautiful function is had both, especially suitable for distributing
Sanitary sewage and using carbon nitrogen phosphorus as the processing of the industrial wastewater of pollutant.
The content of the invention
The purpose of the present invention is for the problem that existing Artificial Wetland Techniques structure it is not compact, take up an area larger, provide
A kind of interior electricity production eversion type current constructed wetland sewage purification system.
What the present invention was realized in：Interior electricity production eversion type current constructed wetland sewage purification system includes water inlet pipe, double
Layer pond body, water plant, porous collector pipe, rotatable elbow and U-shaped drainpipe.
Double-deck pond body includes electricity production internal layer and non-electricity production outer layer;Produce electricity internal layer and non-electricity production outer layer cross section to be circular or
Polygon；It is 5 to produce electricity the ratio between internal layer and non-electricity production outer layer cross sectional area:1-1:1.
Electricity production internal layer be connected with water inlet pipe, electricity production internal layer in filling conducting particle fillers, conducting particle fillers be activated carbon,
One kind in charcoal, coke and metal slag, conducting particle fillers grain size are 1-10mm；
Non- electricity production outer layer is connected with water outlet, and filling non-conductive filler in non-electricity production outer layer, non-conductive filler is quartz
One kind in sand, lime stone, zeolite and volcanic rock, non-conductive packing material size are 5-20mm, conductive particle and non-conductive
Equal planting aquatic plants on particulate filler, the water plant are one kind in canna, reed and thaliadeabata.
Porous collector pipe is connected with U-shaped drainpipe, and the position installation that U-shaped draining bottom of the tube is stretched out outside double-deck pond body is rotatable
Elbow；Change the inclined degree of U-shaped drainpipe by adjusting rotatable elbow, so as to control the water in non-electricity production outer layer filler
Position makes it that saturation/unsaturated state be presented, and increases reoxygenation.
It is using the step of above device progress sewage disposal：
First, sewage, which initially enters, produces electricity internal layer area bottom, and the organic pollution in sewage is metabolized by electricity-producing microorganism, release electricity
Son so as to become the anode of microbiological fuel cell, completes the efficient degradation of organic matter.
2nd, current flow up, and dissolved oxygen concentration constantly raises, at the top of electricity production internal layer area（Microbiological fuel cell
Cathodic region）, nitrification, denitrification denitrogenation process occurs.
3rd, secondary flow enters non-electricity production outer layer zone to current around, adjusts water level using rotatable U-shaped drainpipe, accelerates multiple
Oxygen, and the effects that passing through filtering, absorption, co-precipitation further remove the pollutants such as phosphorus in water removal.
Microbiological fuel cell technology and traditional artificial wetland are closely combined together by the present invention, have given full play to two
Advantage of the person in organic matter degradation and denitrification process, will efficient organic carbon metablism, Microbial denitrogenation and adsorption coprecipitation dephosphorization
The compact control of process is in same artificial swamp.
