Automatic defoaming device for sewage treatment biochemistry pool

An automatic defoaming device for a sewage treatment biochemistry pool comprises a biochemistry pool, a treatment water pool and a recycling water pipe, wherein the biochemistry pool is connected with the treatment water pool which is connected with the recycling water pipe. The automatic defoaming device for the sewage treatment biochemistry pool is characterized by comprising a water spraying pipe which is connected with the recycling water pipe and is arranged in the biochemistry pool. The automatic defoaming device is simple for manufacturing, low in construction cost, and is simple, convenient and fast in practical operation; extra power and water resources are not needed for defoaming during high-pressure atomization, and good defomaing effect can be achieved without defoamer, so that the production cost is lowered, and the sewage treatment efficiency and the treatment effect are improved.
