Mine wastewater treatment is one of the main research topics facing the environmental protection of non-ferrous metal mines in China at present.

In this study, the wastewater treatment system of Zhuyuan 1000 t/d concentrator in Chenzhou polymetallic mine market, Hunan Province was taken as the research object. On the basis of previous studies, the present situation and existing problems of wastewater treatment and utilization in Shizhuyuan concentrator were studied and designed, and the selection of wastewater treatment technology and the design of sewage treatment plant were improved. In the process selection and improvement, in the process of limestone and in the process of-and-return, the final design of sewage treatment plant and the improvement of the use of limestone in the process, and in the process of limestone, the process of improving, settling, flocculation, clarification and sludge five treatment systems, through the control of various technical parameters, wastewater discharge standards. The main features of this process are:

The wastewater treatment system is designed as many small independent systems in unattended form. The wastewater treatment process also involves the balance control of chemical reaction, that is, the control of the lagging links of the system (such as the control of pH value), so there is still a lot of work to be done to make the system run stably and reach the wastewater discharge standard. According to the flow rate of the wastewater reactor, all kinds of chemicals added were calculated, and the chemical treatment was normal. Adjust the pH value of water by adding a water tank in the final HC 1. When the turbidity of water is unqualified, stop using the wastewater entering the system, and return the water in the water tank to the reaction tank for re-treatment. Sludge in clarifier is automatically discharged. The amount of sludge in the clarifier is measured by the sludge detector in the clarifier, and the control system controls the discharge of filtered sludge according to the height of sludge in the clarifier.

Finally, the sewage treatment plant is designed from the aspects of site selection, general layout, main building facade layout, equipment and investment estimation.
