Embodiment 1

[0027] Embodiment 1, the bypass treatment of river sewage

[0028] 1. Establishment of bypass purification system for river sewage

[0029] Taking the Daqing River, the inflow river of Dianchi Lake in Yunnan, as an example, a bypass purification system for river sewage was established to conduct a sewage treatment test. On the riparian belt on one side of the river, use the idle wasteland and ponds for reconstruction, and establish a bypass treatment system that diverts the river sewage. The structure diagram of the purification system for the river sewage treatment is as follows Figure 1-4 As shown, the purification system is composed of a grit chamber 1, a biological contact oxidation pond 2, a sedimentation pond 3 and an aquatic plant purification pond 4; the outlet of the grit chamber 1 is connected to the water inlet of the biological contact oxidation pond 2, and the biological contact oxidation The water outlet of pond 2 is connected with the water inlet of sedimenta...

Abstract

The present invention discloses river sewage treating process and system. The river sewage treating system is one biological contact oxidizing pond with one or several anaerobic / aerobic treating units, each of which consists of one anaerobic pond and one aerobic pond with aerator connected together and provided with microbe enriching stuffing. River sewage is treated in the river sewage treating system. The present invention is suitable for treating river sewage with different kinds of pollutant, and has high water quality and weather adaptability, high treating effect, great treating capacity, low cost and other advantages.

Description

technical field [0001] The invention relates to a method for treating river sewage and a special purification system thereof. Background technique [0002] In recent years, with the rapid growth of my country's economy, my country's river systems have followed the trend of "pollution first and then treatment" in developed countries. According to the "2005 China Environmental Status Bulletin", among the 411 surface water monitoring sections of the seven major river systems of the National Environmental Monitoring Network, the proportion of sections IV and below reached 59%. The water quality of the Yellow River, Songhua River is poor, and the Haihe River is seriously polluted. Big rivers and big rivers have huge water environmental capacity, but the tributaries and small rivers, especially the river sections that flow through cities, receive domestic sewage and industrial and agricultural production wastewater that exceed their self-purification capabilities, and the water q...
