Baffling device and method for treating return water in chlorohydrocarbon-containing sewage

Abstract

The invention discloses a baffling device for treating return water in chlorohydrocarbon-containing sewage. A rotating wheel comprises a wheel motor, a compressor, a shaft cooler, a wheel disc, a brake pad, an angle turning instrument and a scale needle; the wheel motor located at the upper part is in driving connection with a wheel shaft, the shaft cooler is attached to the surface of the wheel shaft, the shaft cooler is made of red copper material and a circumferential coil is wound on the periphery of the wheel shaft, and the shaft cooler is connected with the compressor; the wheel disc isfixedly connected to one side of the wheel shaft and makes contact with a rail; the brake pad is arranged in the wheel disc; the angle turning instrument is arranged at the end part of the brake pad;the scale needle is arranged on one side of the angle turning instrument; the scale needle and the wheel disc rotate coaxially, the angle turning instrument is always kept non-rotating through a gravity center balance method, and the scale needle and the angle turning instrument are jointly used for calculating the rotating angle of the wheel disc. The baffling device for treating the return waterin the chlorohydrocarbon-containing sewage is novel and reasonable in structure, high in pollutant removal efficiency and wide in application range.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to a backwater deflection device and method for treating sewage containing chlorinated hydrocarbons. Background technique [0002] Chlorinated hydrocarbons are colorless toxic liquids, organic compounds that are immiscible with water, and contain Cl in their chemical formula. It can dissolve many substances such as fat and paint, and has a slightly sweet smell of chloroform. Due to the low boiling point of chlorinated hydrocarbons, the liquid chlorinated hydrocarbons are easily volatilized into gaseous states through simple heating and shaking. Chlorinated hydrocarbons have small molecular weight, low density at normal temperature and pressure, low vapor pressure and low vapor density, and are liquid under standard conditions. It is used in the production of DDT and pesticides. Now chlorinated hydrocarbons are mainly used as solvents for ethyl cellulose and man...
