Description
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 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.
Ecological restoring method has build and operating cost is low, maintenance is simple etc. compared with traditional secondary biochemical treatment
Advantage is suitable for not high technology management level, cities and towns of scale is smaller or rural sewage disposal.However engineering practice is found,
To ensure the removal of 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 by 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 same ecological water body cleaning system.This method has investment
Province, operational management are convenient, beautiful function are had both, especially suitable for the sanitary sewage and industrial wastewater using carbon nitrogen phosphorus as pollutant
Processing.
The content of the invention
The purpose of the present invention is for the problem that existing ecological water body purification techniques structure it is not compact, take up an area it is larger,
Provide a kind of inner guide type bacterium algae one microbiological fuel cell ecological water body purification method.
It concretely comprises the following steps：
First, an inner guide type bacterium algae one microbiological fuel cell ecological water body cleaning system is established, including water inlet pipe, double-deck pond
Body, porous collector pipe, water plant, rotatable elbow and U-shaped drainpipe；Double-deck pond body includes electricity production internal layer, non-electricity production outer layer
With free water layer；Internal layer is produced electricity with non-electricity production outer bottom to separate；
Electricity production internal layer bottom is connected with water inlet, middle part filling conducting particle fillers, is free water layer above conducting particle fillers, from
By there is water hole on water layer, hydrobiontic alga is grown in free water layer；Produce electricity inner layer conductive granular filler fill area and free 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 aquatic
Plant.
The conducting particle fillers be activated carbon, charcoal, coke and metal slag in one kind, grain size 1-10mm.
The non-conductive filler be quartz sand, lime stone, zeolite and volcanic rock in one kind, grain size 5-20mm.
The water plant is one kind in canna, reed and thaliadeabata.
The hydrobiontic alga is one or more of chlorella, spirulina, chrysophyceae, hydrodictyon reticulatum.
2nd, sewage, which initially enters, produces electricity internal layer area bottom, and the organic pollution in sewage is degraded by electricity-producing microorganism, is discharged
Electronics so as to become the anode of microbiological fuel cell, completes the efficient degradation of organic matter.
3rd, current flow up, air reaeration, water plant Radial Oxygen Loss from Root and hydrobiontic alga photosynthesis release oxygen,
Dissolved oxygen concentration is made constantly to raise, is the cathodic region of microbiological fuel cell to electricity production internal layer area top, nitrification, denitrification occurs
Denitrogenation.
4th, current enter 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 same ecological water body cleaning system.
