Metallurgical wastewater mainly includes cooling water, washing wastewater, slag flushing water, pickling wastewater, etc. Its characteristics are large water volume, relatively complex water quality and a wide variety of types. If online water quality monitoring of such wastewater is to be conducted, it is essential to first understand the specific water quality conditions and then install the corresponding water quality monitoring equipment.

How can Metallurgical Wastewater be Treated? It can be Viewed from the Following Aspects:

1.Develop and adopt unused or less used water, as well as new processes with no or little pollution, such as dry quenching and direct desulfurization and de-cyanidation from coke oven gas, etc.

2.Comprehensive technologies should be developed, such as: recovering useful substances and thermal energy from wastewater to reduce the loss of material dyes;

3.Additionally, based on the different water quality requirements, a comprehensive balance should be achieved, and the water should be used in series. At the same time, the measures to stabilize the influent water quality should be changed to continuously improve the water recycling rate.

4.Develop zinc treatment process technologies suitable for the characteristics of metallurgical wastewater, such as using magnetic methods to treat steel wastewater. It has the advantages of high efficiency, small land occupation and convenient operation and management.

It should also be noted that no matter what industry it is, real-time monitoring of the discharged wastewater is indispensable! Try to minimize the pollution of originally healthy water sources! There are water process monitoring, drinking water monitoring, sewage monitoring, etc.
