Background

In recent years, the lead smelting industry in China has been developed greatly, and China becomes the largest lead-refining producing country in the world and the second largest lead-refining selling country next to the United states. The lead smelting process is complex, the waste water generation amount is large, and the discharge problem of the production waste water gradually becomes a research subject which needs to be solved urgently along with the increase of the environmental protection pressure. At present, most non-ferrous metal smelting enterprises directly discharge the production wastewater into a production drainage system, and because the water quantity of the part is large, the influence on water balance and environment is great if the part is directly discharged. If the part of the production wastewater can be recycled, a large amount of valuable water resources can be saved, so that the whole production process is more energy-saving and environment-friendly. At present, the main recycling treatment processes for the production wastewater generated in the smelting process in the prior art comprise an electrochemical treatment technology, a steam evaporation crystallization technology, a membrane filtration technology and the like.

The mixed liquid is supplied to a PCF mechanical filter by utilizing the residual pressure, the produced water passing through the PCF mechanical filter enters a PCF water producing pool, the water in the pool is sent to the mechanical filter by a water supply pump, the mechanical filter is used for further filtering the adjusting wastewater on the basis of the filtration of the PCF mechanical filter, the produced water of the mechanical filter is discharged into a low-pressure RO reverse osmosis device, the product water subjected to the step-by-step filtration treatment is stored in a product pool, and the water in the product pool is softened water which can reach the recycling standard and can be pumped to a factory for use; however, there are some fine impurities in the mechanically filtered waste water, which will increase the workload of the reverse osmosis membrane, so the mechanically filtered waste water needs to further remove the fine impurities therein.
