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 insoluble pollutants, but requires aeration equipment, high energy consumption, complicated operation management and high noise

Embodiment 1
[0041] See Figure 1. The system for the treatment and reuse of dispersed small point source sewage of the present invention is composed of an environmental engineering unit, a sedimentation adjustment tank, a biological filter tank and an ozone oxidation unit.
[0042] A sedimentation adjustment tank I is connected with the biological filter II through the pipeline; the biological filter II is connected with the clear water tank III through the pipeline;
[0043] A clean water pool III has two water outlets, one of which is connected to the ozone oxidation unit IV through a pipeline.
[0044] The biofilter II is shown in Figure 2. The filter material in the biofilter is ceramsite filter material, and the sewage enters the biofilter II evenly through the perforated water inlet distribution pipe 6 by means of falling water.
[0045] The system of the present invention is used to treat the sewage in the hippopotamus hall of Wuhan Zoo.
[0046] The hippopotamus pavilion in Wuhan...

The present invention discloses integrated spot source sewage treating technology in environmental engineering technology, and is especially dispersed spot source sewage treating and graded reusing system and its operation process. The spot source sewage treating and graded reusing system includes settling regulation pond, biofiltering pond, clear water pond and ozone oxidizing unit combined together. The settling regulation pond can eliminate partial suspended pollutant and regulate water quality; the biofiltering pond can eliminate organic pollutant, ammonia nitrogen, suspended particle, etc effectively; and the ozone oxidizing unit can further eliminate organic pollutant and sterilize water. The returned water may be used for different purposes. The present invention has the features of obvious treating effect, low running cost, environment friendship, etc.
Description
technical field [0001] The invention belongs to an integrated technology for treating scattered point source sewage by using environmental engineering technology, and in particular relates to a system for treating and separating and recycling scattered small point source sewage and an operation method thereof. Background technique [0002] Due to the high proportion of impermeable urban land, the characteristics of urban non-point source pollution are: it is produced with heavy rain and runoff, and it is sudden. Non-point source pollutants are accumulated in sunny days and discharged in rainy days, and the periodicity of pollution is obvious. Compared with urban areas, the land use types of tourist areas are different from cities, the proportion of impermeable surface is much lower than that of urban areas, and the proportion of green area is higher than that of urban areas. Therefore, in addition to the general characteristics of urban non-point source pollution, non-point...
