Abstract

The invention discloses a power plant industrial wastewater treatment system and method, relates to the technical field of power plant industrial wastewater treatment, and aims at solving the problems that the sludge yield is large when wastewater is treated by an existing activated sludge method, more heavy metal ions exist in the power plant wastewater, the pH value is unbalanced, and then the generated sludge cannot be reutilized. One side of the upper end of an adjusting tank is provided with an industrial wastewater inlet, a coarse screen is mounted in the industrial wastewater inlet, a fine screen is mounted below the coarse screen, slag discharge valves are mounted on one side of the upper surface of the coarse screen and one side of the upper surface of the fine screen, two settling tanks are arranged at the lower end of the adjusting tank, a waste discharge valve is installed at the lower end of the sedimentation tank, a waste discharge pipe is installed at the lower end of the waste discharge valve, a primary sedimentation tank is arranged on one side of the adjusting tank, a first mud valve is installed at the lower end of the primary sedimentation tank, and a mud discharge pipe is installed at the lower end of the first mud valve.

Description

technical field [0001] The invention relates to the technical field of power plant industrial wastewater treatment, in particular to a power plant industrial wastewater treatment system and treatment method. Background technique [0002] Industrial wastewater includes production wastewater, production sewage and cooling water. It refers to wastewater and waste liquid produced in the process of industrial production, which contains industrial production materials, intermediate products, by-products and pollutants produced in the production process lost with water. There are many types of industrial wastewater with complex components. For example, electrolytic salt industrial wastewater contains mercury, heavy metal smelting industrial wastewater contains various metals such as lead and cadmium, electroplating industrial wastewater contains various heavy metals such as cyanide and chromium, petroleum refining industrial wastewater contains phenol, and pesticide manufacturing i...
