Liftable tubular microporous aeration system for river regulation

Abstract

The invention relates to a liftable tubular microporous aeration system for river regulation, which comprises an aeration main pipe, a submerged blower, an aeration branch pipe and an aeration membrane pipe, the submerged blower is connected with the aeration main pipe, one end of the aeration membrane pipe is connected with the aeration branch pipe, the other end of the aeration membrane pipe isprovided with a plug, and the aeration membrane pipe is placed at the bottom of a river, the aeration main pipe is connected with the aeration branch pipe through a flange, and a butterfly valve is arranged at a joint part. The system has the beneficial effects that when a certain aeration branch pipe needs to be overhauled, the butterfly valve can be closed at the aeration branch pipe under the condition that other aeration branches are not turned off, the aeration branch pipe is disconnected from the aeration main pipe at the flange joint, and the bottom aeration membrane pipe can be liftedout of the water surface after being lifted, so that the membrane can be overhauled, maintained or replaced; and the water level in the riverway does not need to be completely pumped in the maintenance process. The mode that the submerged air blower is arranged at the bottom of the riverbed does not occupy the occupied area beside the riverbed, water has the noise reduction function, noise is low,and life of surrounding residents is not affected.

Description

technical field [0001] The invention relates to the technical field of river channel water treatment, in particular to a liftable tube-type microporous aeration system for river channel treatment. Background technique [0002] With the development of industrialization and urbanization, more and more industrial wastewater and urban domestic sewage are discharged into rivers, coupled with the excessive discharge of rural sewage, a large amount of pollutants are directly discharged into the river, far exceeding the self-purification capacity of the river, As a result, the river course is seriously polluted, eutrophication or even black and smelly, which seriously restricts the sustainable development of the social economy. An economical, efficient and non-polluting method is urgently needed to treat the eutrophic water body. At present, many cities have carried out river management measures. The main river management measures include physical methods, chemical methods, biologic...

AI Technical Summary

Problems solved by technology

At present, surface aerators are mostly used in river aeration systems, which have low oxygen transfer efficiency, difficulty in fixing, and are easily affected by water flow; traditional underwater microporous aerators have high oxygen transfer efficiency, but are difficult to maintain, and the blower room occupies a large area. Loud noise, affecting the life of surrounding residents
