Embodiment Construction

[0025] The biological bag of the present invention and the method for treating sewage thereof will be further described in conjunction with the accompanying drawings.

[0026] See attached figure 1 , 3 . First of all, the biological package should be designed and constructed according to the total amount of sewage discharged from the rainwater discharge outlet and the type of sewage discharged, as well as the normal load of the composite filler 5, and the quantity of the composite filler 5 in the biological package should be determined. Since the amount of microorganisms in the river channel is relatively small, it should be increased by 10-30% on the basis of the designed amount of filler, and at the same time, composite filler 5 with filler bracket 6 should be selected as much as possible, so as to improve the rate and amount of film formation , It can also prevent local leakage caused by excessive water flow resistance in the biological bag. Secondly, the location, volum...

Abstract

The biological package treatment method for draining port to river is based on combined complex enzyme-biomembrane-aquatic life technology. In the draining port to river, biological package is set, which has composite stuffing favorable to restoring aquatic life and complex enzyme biopromoter to activate native microbe and promote its growth. The biological package can strengthen the attachment of microbe on the artificial carrier, reinforce the degradation and conversion of sewage, raise the natural reaeration capacity of water and treat the waste water and sewage before being drained into river. The present invention can maintain the self-cleaning capacity and excellent biological environment of river without affecting the flood discharging capacity and the biological landscape.

Description

【Technical field】 [0001] The invention relates to the technical field of environmental protection, in particular to a method for disposing a biological bag at a river channel rainwater outlet to treat disorderly discharged industrial waste water, domestic sewage and rainwater scours. 【Background technique】 [0002] With the development of manufacturing industry and the expansion of urbanization scale, a large amount of industrial wastewater and domestic sewage flow into urban rivers and surrounding water systems, causing the water environment to deteriorate. According to statistics, more than 90% of urban rivers in China are currently polluted to varying degrees. The 2004 China Environmental Status Bulletin shows that among the 412 water quality monitoring sections in the seven major river systems, the proportions of sections with water quality of Grade 1 to Grade 3, Grade 4 to Grade 5, and Grade 5 were 41.8%, 30.3% and 27.9%, respectively, and the wastewater discharge volume...
