Abstract
Description
technical field
[0001] The invention relates to a water body purification treatment device, in particular to a self-moving aeration device for increasing the dissolved oxygen content of the water body. Background technique
[0002] About 80% of the urban rivers in our country have been polluted to varying degrees, the floating garbage on the surface is seriously polluted, and the landscape effect is poor, causing serious urban ecological environment problems. The Department of Pollution Control of the National Environmental Protection Agency conducted a survey on urban river sections, and found that about 87% of the river sections were polluted to varying degrees, of which 11% were heavily polluted, 16% were seriously polluted, 15% were moderately polluted, and 33% were slightly polluted. Only 23% of urban river sections have good water quality. Based on the status quo of pollution, the State Council issued the "Water Pollution Prevention and Control Action Plan" (referred ...
