Abstract
The invention provides a method for treating sewage of an artificial wetland, which utilizes plants, microorganisms and plant roots inhabiting in an underground artificial medium and physical and chemical characteristics of the medium to purify the sewage and consists of a step-shaped multi-stage sub-wetland bed formed by overlapping from top to bottom, wherein each stage of the sub-wetland bed is provided with one or more water outlets to flow the treated sewage into the next stage of the sub-wetland bed.
Description
Technical field
The present invention relates to a kind of method of sewage disposal, especially the method for artificial swamp sewage disposal.
Background technology
Continuous acceleration along with China's Development of China's Urbanization, river course or waterhead area near the community life sewage of a lot of cities and towns periphery enters, caused serious pollution, therefore, disperse point-like source of sewage widely for these, sewage water treatment method with routine is improper, constructed wetland waste water treatment technology is to utilize the root arteries and veins of plant and its surrounding soil microorganism to unite sewage is handled, and outstanding feature is to have overcome that the floor space of other artificial swamp technology is big, polluted underground water, stop up and the problem of passing the winter.
Summary of the invention
The method that the purpose of this invention is to provide the high artificial swamp sewage disposal of a kind of efficient of disposing of sewage.
For realizing that technical scheme provided by the present invention is:
A kind of method of artificial swamp sewage disposal, it is characterized in that sewage through grid in advance at heart the unit remove foreign material and suspended substance, suitably introduce certain clear water, water down the nitrogen in the sewage, phosphoric, by water inlet continuously in undercurrent artificial wetland in sequence batch mode, periodically falling to doing process purifies waste water, water distribution system is evenly distributed in sewage in the artificial swamp section of being made up of hypothallus, sewage flows downward, hypothallus is in dried state, sewage fully contacts with air between matrix pores, and and microorganism, matrix and root system of plant effect, sewage constantly flows into, free-water level forms in the hypothallus, and lifting gradually, and the following water of free-water level continues and microorganism, the root system effect takes place in matrix and plant.
Present method is with respect to the traditional wastewater treatment technology, has ecology, garden style, advantages such as running cost is low, maintenance is simple, non-secondary pollution, is particularly useful for the processing of sanitary sewages such as park, rural area, sub-district.
Embodiment
In the actual treatment, sewage through grid in advance at heart the unit remove foreign material and suspended substance, suitably introduce certain clear water, water down the nitrogen in the sewage, phosphoric, by water inlet continuously in undercurrent artificial wetland in sequence batch mode, periodically falling to doing process purifies waste water, water distribution system is evenly distributed in sewage in the artificial swamp section of being made up of hypothallus, sewage flows downward, hypothallus is in dried state, and sewage fully contacts with air between matrix pores, and and microorganism, matrix and root system of plant effect, sewage constantly flows into, free-water level forms in the hypothallus, and lifting gradually, and the following water of free-water level continues and microorganism, the root system effect takes place in matrix and plant.
Treatment process of the present invention is following steps:
Sewage through grid in advance at heart the unit remove foreign material and suspended substance, suitably introduce certain clear water, water down the nitrogen in the sewage, phosphoric, by water inlet continuously in undercurrent artificial wetland in sequence batch mode, periodically falling to doing process purifies waste water, water distribution system is evenly distributed in sewage in the artificial swamp section of being made up of hypothallus, sewage flows downward, hypothallus is in dried state, sewage fully contacts with air between matrix pores, and and microorganism, matrix and root system of plant effect, sewage constantly flows into, and free-water level forms in the hypothallus, and lifting gradually, when the water surface rises to preset height, water emptying in the hypothallus between the negative pressure-pumping air admission hypothallus space that produces by water, realizes air reaeration in rapid decline process, the cycle of operation finishes, with the continuous heaving and dipping of current wetland phreatic line, the suction atmosphere is a feature to the matrix reoxygenation, can strengthen the oxygenation capacity of wetland, ammonia nitrogen removal efficient is improved more than 3 times, significantly alleviate wetland simultaneously and stop up stifled phenomenon, reduce the wetland area.
Below in conjunction with embodiment content of the present invention is described further:
Embodiment one
Equipment: equalizing tank, flocculation agent pipe, pressure filter;
Treatment process:
Sewage through grid in advance at heart the unit remove foreign material and suspended substance, suitably introduce certain clear water, water down the nitrogen in the sewage, phosphoric, by water inlet continuously in undercurrent artificial wetland in sequence batch mode, periodically falling to doing process purifies waste water, water distribution system is evenly distributed in sewage in the artificial swamp section of being made up of hypothallus, sewage flows downward, hypothallus is in dried state, sewage fully contacts with air between matrix pores, and and microorganism, matrix and root system of plant effect, sewage constantly flows into, and free-water level forms in the hypothallus, and lifting gradually, when the water surface rises to preset height, water emptying in the hypothallus between the negative pressure-pumping air admission hypothallus space that produces by water, realizes air reaeration in rapid decline process, the cycle of operation finishes, with the continuous heaving and dipping of current wetland phreatic line, the suction atmosphere is a feature to the matrix reoxygenation, can strengthen the oxygenation capacity of wetland, ammonia nitrogen removal efficient is improved more than 3 times, significantly alleviate wetland simultaneously and stop up stifled phenomenon, reduce the wetland area;
Embodiment two
Batching: aluminum chloride hydrocarbon complex, polyacrylamide, its treatment process is with embodiment one.
The present invention utilizes plant, microorganism, the root system of plant of perching in the underground artificial dielectric, and the physics that medium had, chemical property are with sewage purification, constitute by the overlapping stepped multistage son that forms is wetland bed from top to bottom, each grade is wetland bed, and all to have one or more water outlets that the sewage of treated mistake is flowed into next stage wetland bed, has that floor space is little, characteristics of applied range, good purification.
