Integrated sewage treatment device

Abstract

The invention provides an integrated sewage treatment device. The integrated sewage treatment device structurally comprises a first chemical-adding reaction tank, a second chemical-adding reaction tank, an inclined pipe precipitating tank and an active carbon filter which are successively communicated with each other, wherein stirrers are arranged at the top ends of the first chemical-adding reaction tank and the second chemical-adding reaction tank; a water inlet is formed in the top of the first chemical-adding reaction tank; anticorrosion layers are arranged on the inner walls of the firstchemical-adding reaction tank, the second chemical-adding reaction tank and the inclined pipe precipitating tank; precipitated sludge hoppers are arranged at the lower part of the inclined pipe precipitating tank; a sludge discharging pipe is mounted at the bottom of each precipitated sludge hopper; an intermediate water tank is arranged between the active carbon filter and the inclined pipe precipitating tank; chemical storage areas are arranged between the intermediate water tank and the active carbon filter; the top of each chemical storage area is connected with a chemical preparing area;the chemical preparing areas are in pipeline connection with the first chemical-adding reaction tank and the second chemical-adding reaction tank; a PLC control cabinet is arranged on one side of theactive carbon filter. The integrated sewage treatment device has the advantages that the device is compact in layout, simple in process and convenient in transportation management, the equipment investment is reduced, a good treatment effect is ensured, the chemical cost is controlled, the secondary pollution is avoided, the service life of the device is prolonged, and the device is convenient andflexible in operation management.

Description

technical field [0001] The invention relates to integrated sewage treatment equipment, specifically designs groundwater and sewage treatment equipment, and belongs to the technical field of groundwater and sewage treatment. Background technique [0002] With my country's continuous emphasis on environmental protection, how to improve the purification effect of sewage to meet the discharge standards, and how to improve purification efficiency, reduce energy consumption, and simplify equipment have become the top priority of sewage treatment. According to the status quo of the existing sewage treatment technology, through the integration of different process technologies, the equipment is improved, and the modern sewage treatment technology is continuously developed and improved, so as to realize the efficient and low energy consumption treatment of sewage. [0003] Physical, chemical and biological methods are commonly used sewage treatment methods. Among them, the chemical ...
