Novel water course aeration device, mounting, using method and uses thereof

Abstract

The invention provides a novel river aerator, comprising an air inlet pipe, a main connection pipe, an air distribution trunk pipe, a changeable microporous aerator, a clump weight and an indication regulating rod. One end of the air inlet pipe is connected with the air outlet pipe of an oxygenation pump in a fixing part on the bank. The other end of the air inlet pipe is connected with the main connection pipe through a flexible joint. One end of each of the two air distribution main trunk pipes is separately connected with the main connection pipe at the same time through a tee joint. The other end of each of the two air distribution main trunk pipes is separately the dead end. Two air distribution main trunk pipes are separately and evenly provided with a plurality of air distribution holes. A plurality of changeable microporous aerators is correspondingly installed on the plurality of air distribution holes. The two clump weights and the lower parts of the two dead ends of the two air distribution main trunk pipes are separately and relatively connected and fixed. The indication regulating rod is installed on the main connection pipe. The upper end of the indication regulating rod is exposed on the water surface. The novel river aerator is easy to be installed and repaired, which can perfectly adapt the complicate application condition. The problems of low oxygenation transfer efficiency, poor flow pattern, large disturbance to the sludge on the bottom of the river, high failure probability and so on can be solved.

Description

technical field [0001] The invention relates to the technical field of water pollution control, in particular to a novel river channel aerator and its installation and use method and application. Background technique [0002] At present, the treatment technologies of polluted river water bodies that have been used or tested at home and abroad mainly include water diversion, river aeration and re-oxygenation, bioremediation, in-situ purification of polluted river water, and sediment dredging. Among them, the river aeration and reoxygenation technology has been applied to river management in many countries since the 1960s. Aeration and reoxygenation technology is based on the characteristics of hypoxia after the water body is polluted, artificially filling the water body with air or oxygen to accelerate the reoxygenation process of the water body, so as to increase the dissolved oxygen level of the water body, restore and enhance the vitality of aerobic microorganisms in the w...
