Abstract
The invention discloses a method for purifying domestic sewage by using biological membrane band aerator pipe plant filtering frame wetland. A biological membrane band aerator pipe plant filtering frame wetland purifying pond consists of a wetland pond body, a biological membrane band, a micropore aeration mechanism and a plant filtering frame. The domestic sewage enters into the wetland pond body and is attached with the biological membrane band in aerobic environment to form micro-biosphere; oxygen is supplied evenly in water in the pond by the micropore aeration mechanism to recover the ecological balance of the water body and fully bring the degradation of natural living creatures into play, thereby purifying and improving the water quality. The plant filtering framework can further strengthen the sewage purifying function of a system. Filter materials in the plant filtering frame has the physical filtering action on the suspended materials in the domestic sewage and can biochemically degrade pollutant as the growth carrier of microorganism. The root system of wetland plants has very good absorption to substances in the sewage, such as nitrogen, phosphorus, heavy metals, and the like; as the growth carrier of microorganism, the wetland plants also have the landscape action on a sewage disposal system.
Description
Technical field
The present invention relates to the method for artificial swamp purifying domestic sewage, particularly a kind of method that adopts the biological membrane band aerator pipe plant filtering frame wetland purifying domestic sewage.
Background technology
The general method of traditional artificial swamp purifying domestic sewage is: as matrix, plant wetland plant by rubble, gravel, soil etc. therein, form artificial swamp, by matrix absorption, microbiological deterioration and the plant absorbing realization purification to sanitary sewage.The shortcoming of aforesaid method is low to the purifying treatment efficient of sanitary sewage, and the artificial swamp floor space is big, and system management complexity, management amount are big.And, cause the purifying domestic sewage load of wetland excessive, the easy blockage problem of recycle pump owing to the suspended substance of not removing effectively in the wetland sanitary sewage.
Summary of the invention
The present invention is directed to above-mentioned shortcoming, develop a kind of method that adopts the biological membrane band aerator pipe plant filtering frame wetland purifying domestic sewage, bottom at the biological film zone of artificial swamp setting is provided with micropore aeration pipe, to evenly oxygen supply in the pond water of artificial swamp, build good environment for purification of water quality, water body biosphere, recover the water ecology balance and improve water quality.Simultaneously in the middle of the ranks of biological film zone, increase plant filtering frame, and in plant filtering frame, plant wetland plant, for building good environment in purification of water quality, water body biosphere, remove the suspended substance in the wetland sanitary sewage effectively, and give full play to the natural biology Degradation, and can play biodegradable effect to organic pollutant in the water body, recover the water ecology balance and improve water quality.
The objective of the invention is to realize as follows:
1, builds the biological membrane band aerator pipe plant filtering frame wetland treating pond

C, micro-pore aeration mechanism
Micro-pore aeration mechanism is made up of micropore aeration pipe, air main and gas blower.Gas blower is arranged on the outside of wetland pond body, and gas blower is connected with air main, and air main stretches in the body of wetland pond, is provided with micropore aeration pipe on air main.The diameter of micropore aeration pipe is 18 to 50 millimeters, and micropore aeration pipe can be straight tube, bend pipe, spiral tube, round tube or metal tube.Periphery at micropore aeration pipe is provided with micropore, and the diameter of micropore is 0.5 to 2 millimeter.Gas blower is transported to micropore aeration pipe with air through air main, improves oxygen in water concentration by aeration, strengthens the metabolic activity of microorganism, improves system handles efficient.Biological film zone and micropore aeration pipe are arranged in parallel, and help contacting of air and biological film zone, improve the utilization ratio of oxygen, and the flow shear that produces of aeration helps renewals that come off of biological film zone surface biological film, maintenance processing efficiency simultaneously.
D, plant filtering frame
Plant filtering frame is the cubes filter frame, can be made of plant roots and stems, plastics or metal material, and the shape of plant filtering frame, size can be generally long 1 to 2 meter, wide about 0.5 to 1 meter, dark about 0.7 to 1 meter rectangle cubes the best according to determining on the spot.Fill filtrates such as rubble, sand grains, slag in the plant filtering frame, and plant wetland plants such as Canna generalis Bailey, cyperus alternifolius, cattail, reed.Filtrate in the plant filtering frame has the effect of physical filtering to the suspended substance in the sanitary sewage, and can be used as the microorganism growth carrier, and pollutent is carried out biochemical degradation.The root system of wetland plant has good sorption to materials such as the nitrogen in the sewage, phosphorus, heavy metals, and makes Sewage treatment systems have landscape function.Plant filtering frame can be dismantled separately, conveniently carries out management and operations such as filter residue cleaning, vegetation pruning replacing.
2, adopt the flow process of biological membrane band aerator pipe plant filtering frame wetland purifying domestic sewage
Sanitary sewage enters in the body of wetland pond, in the environment of aerobic, adhere to formation microorganism circle with biological film zone, microorganism is to the biological purification of sanitary sewage in the body of pond, by evenly oxygen supply in the micro-pore aeration mechanism pool water within, recover the water ecology balance, give full play to the natural biology Degradation, realize the improvement of purification of water quality and water quality.Further consolidation system is to the purification function of sewage for plant filtering frame, and the filtrate in the plant filtering frame has the effect of physical filtering to the suspended substance in the sanitary sewage, and can be used as the microorganism growth carrier, and pollutent is carried out biochemical degradation.The root system of wetland plant has good sorption to materials such as the nitrogen in the sewage, phosphorus, heavy metals, and can be used as the microorganism growth carrier, and wetland plant also makes Sewage treatment systems have landscape function.
Adopt purifying domestic sewage of the present invention, biological film zone can increase the biomass of microorganism greatly, and micro-pore aeration mechanism strengthens microbic activity, the processing efficiency height, and floor space is much smaller than traditional artificial swamp.Simultaneously,, be easy to administer and maintain, overcome the shortcoming that traditional artificial swamp stops up easily because biological film zone, plant filtering frame are removed suspended substance in the wetland sanitary sewage effectively to pollutent.
