Problems solved by technology

However, the chemical defoaming method generally has the following problems: secondary pollution to the environment, low defoaming efficiency, high price, etc.
Most of the above-mentioned mechanical defoamers have the following problems in practical application: the processing efficiency is low during use, the foam drop is limited, and the foam with high water content cannot be processed; the liquid produced after foam separation cannot be removed in time, resulting in secondary Foaming, resulting in a more stable secondary foam; poor universality; stirring or centrifugal defoaming process often requires high energy consumption, etc.

Abstract

The invention relates to the technical field of sewage treatment and relates to an assemblable biochemical pool defoaming device and a defoaming method. The defoaming device comprises a defoaming unit; a foam collecting device and a stirring defoaming device are arranged in the defoaming unit; the defoaming unit is designed into a polyhedral structure; a propeller is mounted at the driving end ofthe defoaming unit; the foam collecting device is arranged on the side wall of the defoaming unit; the stirring defoaming device is arranged in an inner cavity of the defoaming unit; the foam collecting device comprises a plurality of foam collecting pipes; a plurality of built-in foam collecting through holes are formed in the side wall of the defoaming unit; a stirring motor is arranged on the stirring defoaming device; a stirring rod is installed at the driving end of the stirring motor; a plurality of stirring paddles are installed on the stirring rod; and a foam warning line is arranged in the defoaming unit. Any chemical defoaming agent does not need to be added, the foam content of a biochemical pool can be effectively reduced, the oxygenation efficiency is improved, and the water purification efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an assembleable biochemical pool defoaming device and a defoaming method. Background technique [0002] When biochemical treatment of sewage, due to various factors such as sludge residence time, PH value, dissolved oxygen, temperature, etc., a large amount of foam will be generated in the water treatment tank. These foams will have a certain viscosity and will hinder oxygen from entering the exposure. The mixed liquid of the gas pool will reduce the oxygenation efficiency, increase the content of suspended solids in the effluent, and cause many hazards such as deterioration of the effluent quality. At present, the countermeasures to control foam mainly include: spraying water to increase surface agitation, adding bactericide or defoamer, but the effect of the agent can only reduce the growth of foam, but cannot eliminate the formation of foam and reduce the sludge age. ...
