Problems solved by technology
[0004] When using activated sludge to treat eutrophic water bodies, because the microorganisms in the activated sludge will proliferate in large quantities, the volume of the activated sludge itself will also increase accordingly, so it is usually necessary to stop working after working for a period of time in the exposure pool. Treat excess sludge to avoid too much activated sludge in the exposure pool, which will not easily affect the sewage treatment effect of activated sludge. The exposure pool cannot work continuously, which will have a certain impact on the sewage treatment efficiency

Embodiment 1
[0035] See Figure 1-7 , A self-regulating activated sludge municipal sewage treatment device, comprising an exposure tank 1 and a reaction well 2 matched with each other, and the reaction well 2 is sleeved in the exposure tank 1, and the exposure tank 1 and the reaction well 2 are fixedly connected The reaction well 2 connects the two parts of the atmosphere reaction tank 3 and the sewage tank 4 in the exposure tank 1. The reaction tank 3 is located inside the reaction well 2, the sewage tank 4 is located outside the reaction well 2, and the bottom plate of the exposure tank 1 is fixedly connected with the inlet Water pipe 5, one end of the water inlet pipe 5 runs through the exposure tank 1 and extends into the reaction tank 3. The other end of the water inlet pipe 5 is connected to the water pump located in the sewage tank, and the sewage is continuously injected into the reaction tank 3 through the water pump. The cultivation embankment 9 that matches with itself is fixedly ...

The invention discloses a self-adjusting activated sludge municipal sewage treatment device and belongs to the field of municipal sewage treatment, the invention discloses a self-adjusting activated sludge municipal sewage treatment device. When the exposure pool and the reaction well work normally, the water inlet pipe can continuously inject sewage into the reaction tank; when passing through cultivation embankment, the sewage is divided by the cultivation column, so that the contact area between the culture column and sewage is greatly increased; as the sewage treatment process proceeds, the activated sludge bacterial colony can continuously proliferate, wherein the bacteria gradually overflow out of the inner cultivation tank and grow into the outer cultivation tank; at the moment, thesurface of the cultivation dike is flushed by sewage, so that activated sludge colonies located in the outer cultivation tank easily fall off from the cultivation dike and are discharged into the treatment tank together with sewage through the through holes and the blow-off pipe to be treated, so that the exposure tank can be promoted to continuously work. According to the treatment device, the exposure tank does not need to be stopped to specially perform activated sludge treatment operation, and the negative influence on the sewage treatment efficiency is not easily caused.
Description
Technical field [0001] The invention relates to the field of urban sewage treatment, and more specifically, to a self-regulating activated sludge urban sewage treatment device. Background technique [0002] Urban sewage mainly refers to domestic sewage, industrial waste water and runoff sewage within the scope of urban areas. During the construction of factories, sewage treatment facilities need to be constructed and inspected before they can start. Therefore, most of the industrial sewage is generally produced by the factory itself. To solve the problem, domestic sewage and runoff sewage are different from industrial sewage. Generally, they do not contain too many heavy metal ions. On the contrary, they contain a large amount of organic matter and form a eutrophic water body. [0003] The most commonly used method for treating eutrophic water bodies containing a large amount of organic matter is the activated sludge method. The complex microorganisms in the activated sludge and th...
