Chemical dispensing device for sewage treatment

Abstract

The invention discloses a chemical dispensing device for sewage treatment, and belongs to the field of sewage treatment. The chemical dispensing device for the sewage treatment comprises a chemical dispensing cabinet, the interior of the chemical dispensing cabinet is fixedly connected with a processing cabinet, one end, far away from each material storage tank, of one corresponding material outlet pipe is arranged in the processing cabinet, and one end, far away from sliding rods, of each connection rod is fixedly connected with a sample taking sleeve. According to the device disclosed by theinvention, different chemicals are dispensed through a first chemical dispensing pipe and a second chemical dispensing pipe, a first material storage tank is an acidic material storage tank, a secondmaterial storage tank is an alkaline material storage tank, in the dispensing process, chemicals to be dispensed are conveyed into the processing cabinet through open and close of valves, the chemicals processed in the processing cabinet are discharged through a third chemical dispensing pipe and a fourth chemical dispensing pipe, so that sewage is processed; the chemicals are processed in the processing cabinet, so that quantitative dispensing is realized; and the sewage is sampled through a sample taking sleeve located on the bottom wall of the chemical dispensing cabinet, so that workers observe water quality conveniently, and adjustment of the amount of the chemicals to be dispensed is facilitated.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment dosing device. Background technique [0002] The country has strict standards for the quality of sewage discharge, and has strict numerical standards for PH value, turbidity, oxygen consumption, etc. after sewage treatment, because the sewage discharged from the factory will become acidic water or alkali due to the factory reagents. In the process of sewage treatment, sewage treatment dosing machines are generally used to treat sewage. [0003] The structure and performance of the existing sewage treatment device is relatively simple. During the use process, the correct medicine cannot be put in according to the acidity and alkalinity of the sewage, which leads to the substandard sewage treatment quality, which leads to the need for further treatment of the sewage, which increases the cost of sewage treatment. Therefore, a drug delivery device that ca...

Problems solved by technology

[0003] The structure and performance of existing sewage treatment devices are relatively simple. During use, the correct drug cannot be injected according to the acidity and alkalinity of sewage, resulting in the quality of sewage treatment not up to standard, which leads to the need for further treatment of sewage, which increases the cost of sewage treatment. Therefore, a drug delivery device that can be delivered accurately and quantitatively is particularly important
