Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

In the description of the present utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," "outer," and the like indicate or are based on the orientation or positional relationship shown in the drawings, merely to facilitate description of the present utility model and to simplify the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present utility model.

Examples:

referring to fig. 1, the present utility model provides a technical solution: the combined industrial sewage treatment structure comprises an adjusting tank 2, wherein an outlet of the adjusting tank 2 is connected with an inlet of a hydrolysis acidification tank 3, an outlet of the hydrolysis acidification tank 3 is connected with an inlet of an anaerobic tank 4, an outlet of the anaerobic tank 4 is connected with an inlet of an anoxic tank 5, and an outlet of the anoxic tank 5 is connected with an aerobic tank 6;

the hydrolysis acidification tank 3 is arranged on the right side of the regulating tank 2, the anaerobic tank 4 is arranged on the right side of the hydrolysis acidification tank 3, the anoxic tank 5 is arranged on the right side of the anaerobic tank 4, and the aerobic tank 6 is arranged on the right side of the anoxic tank 5.

Preferably, the combined industrial sewage treatment structure further comprises an accident pool 1, and an outlet of the accident pool 1 is communicated with the regulating pool 2 through a pipeline. By setting the accident pool 1, a temporary emergency can be handled. An accident pool (accident water collecting pool) is one of structures required in the sewage treatment process, and is generally arranged when treating high-concentration wastewater discharged by some factories such as chemical industry, petrochemical industry and the like. The reason is that when the factories produce accidents, a large amount of high-concentration organic wastewater with large pH value fluctuation is discharged in a short time, and if the wastewater directly enters a sewage treatment system, the wastewater can bring high impact load to the running biological treatment system, and the influence caused by the high impact load needs a long time to recover and sometimes causes fatal damage. In order to avoid the influence of accident water on the sewage treatment system, accident pools are arranged in many sewage treatment plants for storing the accident water.

Preferably, a one-way valve for the accident pool 1 to the regulating pool 2 is arranged on a pipeline communicated between the accident pool 1 and the regulating pool 2. By the arrangement of the one-way valve, sewage in the accident pool 1 can flow into the regulating pool 2, and sewage in the regulating pool 2 can not flow into the accident pool 1 reversely.

Preferably, the internal volume of the accident pool 1 is 4-6 times that of the regulating pool 2.

Preferably, a partition plate is arranged in the aerobic tank 6, and the partition plate divides the interior of the aerobic tank 6 into S-shaped flow channels. Adding sewage into the aerobic tank 6

Preferably, the number of the hydrolysis acidification tank 3, the anaerobic tank 4, the anoxic tank 5 and the aerobic tank 6 is the same, and the number of the hydrolysis acidification tank 3, the anaerobic tank 4, the anoxic tank 5 and the aerobic tank 6 is not less than one. A group of treatment systems are formed among the hydrolytic acidification tank 3, the anaerobic tank 4, the anoxic tank 5 and the aerobic tank 6,

working principle: sewage enters the regulating tank 2, the sewage is regulated in the regulating tank 2, industrial wastewater changes along with the change of production conditions in the discharge process, and the conditions of uneven water quality and unstable water quantity exist. Particularly when accidents occur in production or rainwater is particularly high, the quality and quantity of the wastewater are changed more, the wastewater treatment process is abnormal due to the change, the treatment effect is reduced, and the design load of treatment equipment cannot be fully exerted. In order to make the treatment process work normally, the wastewater is not influenced by the change of the peak flow or the peak concentration of the wastewater, and the wastewater is required to have a relatively stable water quantity and uniform water quality before being treated, and the water quality and the water quantity must be regulated. The setting of the regulating reservoir 2 can meet this requirement.

The water in the regulating tank 2 sequentially enters the hydrolysis acidification tank 3, the anaerobic tank 4, the anoxic tank 5 and the aerobic tank 6 for corresponding treatment.
