Sewage sampling equipment and method for sewage treatment

Abstract

The present invention discloses sewage sampling equipment and method for sewage treatment. The equipment comprises an equipment body, wherein a sampling opening is formed in the middle of the equipment body, a sampling pipe is arranged in the sampling opening in a penetrating mode, mounting grooves are formed in the two sides of the sampling pipe, driving mechanisms are fixedly mounted in the mounting grooves, and a floating ring is fixedly mounted on the outer wall of the lower end of the equipment body; a rotary disc is fixedly installed at the top end of the equipment body and rotationallyconnected with the equipment body, a plurality of sampling bottles are detachably installed at the top of the rotary disc, liquid inlets are formed in the top ends of the sampling bottles and connected with sampling pipes through pipelines; exhaust ports are formed in the upper ends of the side walls of the sampling bottles and connected with the output end of a vacuum pump through pipelines; andthe vacuum pump is fixedly installed in the equipment body. According to the ivnention, the driving mechanism drives the sampling pipe to move up and down, so that water can be sampled at different depths, and the accuracy and stability of sewage quality monitoring are improved.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a sewage sampling device and method for sewage treatment. Background technique [0002] Among the water pollution caused by human production activities, the water pollution caused by industry is the most serious. Such as industrial wastewater, which contains many pollutants and complex components, not only is not easy to purify in water, but also difficult to deal with. Industrial wastewater is the most important cause of water pollution caused by industrial pollution. [0003] In the process of sewage treatment, sewage needs to be sampled. At present, sewage sampling is generally carried out on the surface water, and water at different depths cannot be sampled deep into the water. There are shortcomings such as difficult sewage extraction, poor detection stability, and low accuracy. Therefore, there is an urgent need to develop a sampling device for sewage water quality detecti...

[0003] In the process of sewage treatment, sewage needs to be sampled. At present, the sampling of sewage is generally carried out on the surface water, and it is impossible to sample water at different depths deep into the water. There are shortcomings such as difficult sewage extraction, poor detection stability, and low accuracy. Therefore, there is an urgent need to develop a sampling device for sewage water quality testing that can go deep into the water to sample water at different depths, which is easy to extract sewage, has good stability in sewage detection, and high accuracy
