A kind of inner guide type bacterium algae one microbiological fuel cell ecological water body purification method
Technical field
The invention belongs to waste water control methods, and in particular to a kind of inner guide type bacterium algae one microbiological fuel cell ecological water
Body purification method.
Background technique
With the rapid development of social economy, water environment situation in China's is increasingly serious.The great number of issues that water pollution causes
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, dispersibility, special heterogeneity, the pollution control and operation in rural area in addition
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.
Ecological restoring method has build and operating cost is low, maintenance is simple etc. compared with traditional secondary biochemical treatment
Advantage, is suitable for that technology management level is not high, the lesser cities and towns of scale or rural sewage treatment.However engineering practice is found,
For the removal for guaranteeing carbon, nitrogen in water, it usually needs larger area completes organic carbon removal and nitrification, denitrification process, limits
The engineering of the technology is promoted.
For this problem, the present invention passes through inner guide type bacterium algae one microbiological fuel cell ecological water body purification method,
Using electricity-producing microorganism and the synergistic effect of hydrobiontic alga, by organic carbon metablism, Microbial denitrogenation and the sorption-coprecipitation in sewage
Dephosphorization process compact control in shallow lake realizes efficiently removal in the same ecological water body purification system.This method has investment
Province, operational management are convenient, beautiful function are had both, especially suitable for using carbon nitrogen phosphorus as the sanitary sewage of pollutant and industrial wastewater
Processing.
Summary of the invention
It is not compact the purpose of the present invention is being directed to existing ecological water body purification techniques structure, take up an area larger problem,
Provide a kind of inner guide type bacterium algae one microbiological fuel cell ecological water body purification method.
Specific steps are as follows:
One, an inner guide type bacterium algae one microbiological fuel cell ecological water body purification system is established, including water inlet pipe, double
Layer pond body, porous collector pipe, water plant, rotatable elbow and U-shaped drainpipe;The double-deck pond body includes electricity production internal layer, non-electricity production
Outer layer and free water layer;It produces electricity internal layer and non-electricity production outer bottom separates;
Electricity production internal layer bottom is connected with water inlet, and conducting particle fillers are filled at middle part, is Free water above conducting particle fillers
Layer, there is water hole on free water layer, grows hydrobiontic alga in free water layer;Produce electricity inner layer conductive granular filler fill area and freedom
Water layer height ratio is 10:1-3:1;
Non-conductive filler is filled in non-electricity production outer layer, is planted on conducting particle fillers and non-conductive filler
Water plant.
The conducting particle fillers are one of active carbon, charcoal, coke and metal slag, partial size 1-10mm.
The non-conductive filler is one of quartz sand, lime stone, zeolite and volcanic rock, partial size 5-20mm.
The water plant is one of canna, reed and thaliadeabata.
The hydrobiontic alga is one or more of chlorella, spirulina, chrysophyceae, hydrodictyon reticulatum.
Two, sewage initially enters electricity production internal layer area bottom, and the organic pollutant in sewage is degraded by electricity-producing microorganism, discharged
Electronics completes the efficient degradation of organic matter to become the anode of microbiological fuel cell.
Three, water flow flows up, and air reaeration, water plant Radial Oxygen Loss from Root and hydrobiontic alga photosynthesis discharge oxygen,
It increases dissolved oxygen concentration constantly, is the cathodic region of microbiological fuel cell to electricity production internal layer area top, nitrification, denitrification occurs
Denitrogenation.
Four, water flow enters non-electricity production outer layer by the water hole above free water layer, U-shaped by adjusting rotatable elbow change
The inclined degree of drainpipe, can control it is non-electricity production skin granulate filler in water level, make its present table/saturation/
Reoxygenation is accelerated in unsaturated state;Non- electricity production outer layer retains the hydrobiontic alga in free water layer by the filtration of filler, simultaneously
Further remove water pollutant.
The present invention by microbiological fuel cell technology and Traditional Ecological water body purification Integration ofTechnology, and by electricity-producing microorganism with
The purification function of algae is coupled, and has given full play to advantage of each factor in pollutant metabolic process, by efficient organic carbon generation
It thanks, the compact control of removal of nitrogen phosphorus is in the same ecological water body purification system.
