Description

Technical Field

[0002] With the continuous upgrading and transformation of electroplating enterprises, the standardization of management, and the elimination of backward production processes, the quality of wastewater discharged by enterprises has improved. However, in order to save production costs, some business owners secretly discharge some concentrated liquids and waste liquids that are not allowed to be discharged into the sewage station into the wastewater, and flow into the sewage station together with the wastewater. The discharge of concentrated liquids and waste liquids greatly increases the difficulty and cost of treatment at the sewage station, and in serious cases directly affects the normal and stable operation of the entire sewage treatment system.

[0003] In the prior art, the raw wastewater is usually guided to the water inlet of the collection barrel through a special pipe, and water quality detection equipment (such as pH value, conductivity, heavy metal content, etc.) is installed inside the barrel. The monitoring device is usually connected to the data recording and analysis system, which can display data in real time, record changing trends, and issue an alarm when necessary so that timely measures can be taken. When the wastewater in the collection barrel reaches a certain amount or needs to be treated, the wastewater can be discharged to the designated treatment system or discharge point through the outlet and the matching valve.

[0004] However, there are impurities and suspended particles in the wastewater raw water. When they enter the collection barrel, they are easily attached to the inner wall of the collection barrel, causing corrosion of the barrel body or blockage of the outlet pipe. The pollutants in the wastewater raw water entering the collection barrel are unevenly distributed, forming a concentration gradient or stratification in the barrel, resulting in inaccurate monitoring and sampling results and deviations.
