Problems solved by technology

However, conventional filtration methods have basically no effect on the removal of dissolved pollutants in water bodies, and dissolved pollutants will accumulate in water bodies
The biological aerated filter system uses the biofilm method to treat pollutants in water, and has a good removal effect on both soluble and

Abstract

The present invention belongs to the field of rain water/sewage treating environment engineering and ecological engineering technology, and is especially one rain water/sewage purifying biological and ecological filtering system and its operation process. The system consists of biofilters as environment engineering units and ecological filters as ecological engineering units. The biofilters can eliminate organic pollutant, ammonia nitrogen, suspended solid, etc from sewage and needs no aerator. The serially connected ecological filters have high treating effect, front settling tank to reduce the load of the subsequent ecological filters, and plant growing to further purify water. The present invention has the features of obvious water purifying effect, low running cost, environment friendship, water saving, etc. The treated rain water/sewage may be used in irrigation or for other purpose.

Description

technical field [0001] The invention belongs to an integrated technology for treating rain / sewage by using environmental engineering technology and ecological engineering technology, and in particular relates to a biological-ecological filter system and an operating method for purifying rain / sewage. Background technique [0002] Urban non-point source pollution is one of the main reasons for the deterioration of water environment quality. From the point of view of time, the non-point source pollution of cities has discontinuous emissions from pollution sources. Pollutants accumulate on sunny days and are discharged on rainy days; from the perspective of pollutant types, urban non-point source pollutants include total suspended solids, total nitrogen, total phosphorus, COD cr , Escherichia coli, petroleum hydrocarbons, heavy metals, pesticides, etc. The types of pollutants and emission intensity are closely related to factors such as the degree of development of the city, the...
