Installation method of integrated domestic sewage collection and recycling treatment box

Abstract

The invention discloses an integrated domestic sewage collection and recycling treatment box installation method, which comprises a front plate, a rear plate, side plates, a bottom plate and separation plates, the side plates, the front plate and the rear plate form a cavity, the front plate, the rear plate and the side plates are all welded on the bottom plate, the separation plates are fixed on the front plate, the rear plate and the bottom plate, and the cavity is divided into a settling zone, a water inlet zone and a water outlet zone; the settling zone is used for removing insoluble suspended solids and floating substances in the sewage; and the first biodegradation area is used for degrading pollutants in the sewage conveyed by the settling area. The adjusting area is used for increasing the dissolved oxygen amount of the sewage conveyed by the first biodegradation area. The second biodegradation area is used for degrading pollutants in the sewage conveyed by the adjusting area again. The water storage area is used for storing the water conveyed by the second biodegradation area, and the water treated in the water storage area can be reused. Therefore, the sewage is treated, the relevant water quality standard issued by the state is met, and the collected water source can be recycled.

Description

technical field [0001] The invention belongs to the technical field of domestic sewage treatment, and in particular relates to an installation method of a treatment box for integrated domestic sewage collection and recycling. Background technique [0002] The domestic sewage treatment process generally determines the degree of sewage treatment and the corresponding treatment process according to the utilization or discharge of domestic sewage and considering the natural purification capacity of the water body. The treated sewage, whether used in industry, agriculture or recharge to supplement groundwater, must meet the relevant water quality standards issued by the state. [0003] Modern sewage treatment technology can be divided into primary, secondary and tertiary treatment processes according to the degree of treatment. The primary treatment of sewage applies physical methods, such as sieving, sedimentation, etc., to remove insoluble suspended solids and floating substan...

AI Technical Summary

Problems solved by technology

The tertiary treatment is advanced treatment, the effluent water quality is better, even can meet the drinking water quality standard, but the treatment cost is high, except in some countries and regions that are extremely short of water, it is rarely used
