Problems solved by technology

Generally, the water quality and quantity of the influent of sewage treatment plants fluctuate greatly. The treatment effect of traditional sewage treatment processes is easily affected by the water quality and quantity of upstream industrial wastewater. Affect the final effluent compliance rate of the sewage treatment plant
Therefore, it is necessary to optimize the sewage treatment plant, but the existing sewage treatment plant has inconvenient connections among the process areas and poor emergency support capabilities

Embodiment 1

[0018] In this sewage treatment plant, when valves F5 and F6 are opened in the pretreatment intelligent comprehensive pool, the sludge from the back-end biological system can flow back to the pretreatment intelligent comprehensive pool through the valve F5, realizing the external discharge of sludge from the sludge pool 8 And return, and realize the internal return of sludge through the valve F6.

Embodiment 2

[0020] The pretreatment intelligent comprehensive pool of this sewage treatment plant can realize homogeneous adjustment when opening valve F2, valve F3, and closing valve F1, valve F4, valve F5, valve F6, valve F7, valve Z5, valve Z8, and valve Z9 Homogeneous regulation in pool 2.

Embodiment 3

[0022] The pretreatment intelligent comprehensive pool of this sewage treatment plant opens valve F1, valve F3, valve Z2, valve Z8, and closes valve F2, valve F4, valve F5, valve F6, valve F7, valve Z1, valve Z4, valve Z6, When the valve is Z9, the dual operation of the homogeneous adjustment pool 2 and the accident emergency pool 1 can be realized.

Abstract

The invention discloses a sewage treatment plant pretreatment intelligent comprehensive pool. The intelligent comprehensive pool comprises an accident emergency pool, a homogenizing regulation pool and a sedimentation pool, and the accident emergency pool and the sedimentation pool are located on the two sides of the homogenizing regulation pool respectively. When the intelligent comprehensive pretreatment pool for the sewage treatment plant is used, according to the online detection result of the inflow water quality, reagents of different types and concentrations are added into different functional areas in an auxiliary manner, and the emergency and pretreatment effects of the sewage treatment plant are achieved; the whole pretreatment intelligent comprehensive pool is reasonable in structural design and high in adaptability to inflow water quality and quantity fluctuation, the influence of the water quality and quantity fluctuation on subsequent processes is reduced, the occupied area is reduced, the investment and operation cost is reduced, meanwhile, different process effects can be achieved by adaptively adjusting all valves according to requirements, and the emergency guarantee capacity is high.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a pretreatment intelligent comprehensive pool of a sewage treatment plant. Background technique [0002] With the increasingly prominent environmental problems in our country, the national and local governments pay more and more attention to the requirements of environmental protection, and put forward higher requirements for the discharge standards of sewage treatment plants. Generally, the water quality and quantity of the influent of sewage treatment plants fluctuate greatly. The treatment effect of traditional sewage treatment processes is easily affected by the water quality and quantity of upstream industrial wastewater. Affect the final effluent compliance rate of the sewage treatment plant. Therefore, it is necessary to optimize the sewage treatment plant, but the existing sewage treatment plant has inconvenient connections among the process areas and poor emerg...
