Abstract

The invention discloses a heavy metal zero discharge treatment system which comprises a pretreatment system, a low-concentration cleaning wastewater pretreatment system and a high-concentration wastewater treatment system, the low-concentration cleaning wastewater pretreatment system comprises a sterilization and ultrafiltration unit and a multi-stage RO concentration unit, and the output end of the pretreatment system is connected with the water inlet end of the sterilization and ultrafiltration unit; the output end of the sterilization and ultrafiltration unit is connected with the multi-stage RO concentration unit, and the output end of the multi-stage RO concentration unit is connected with the input end of the high-concentration wastewater treatment system. The heavy metal zero-discharge treatment system is simple in structure, reasonable in design and easy to produce, the structure of the discharge system is optimized, multi-stage purification treatment is achieved, the sewage treatment effect is greatly improved, zero discharge is achieved, and therefore the heavy metal zero-discharge treatment system better meets the production requirement.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a heavy metal zero discharge treatment system and a working method thereof. Background technique [0002] Heavy metal wastewater treatment refers to the process of purifying the heavy metals contained in sewage to meet the water quality requirements of a certain water body for drainage or reuse. [0003] Although the existing heavy metal wastewater treatment system can treat sewage to a certain extent, due to the difference in its equipment and treatment methods, the treatment will not be thorough enough and the problem of residual discharge will occur. Therefore, the existing heavy metal wastewater treatment technology is still There is room for improvement. Contents of the invention [0004] Purpose of the invention: In order to overcome the above disadvantages, the purpose of the present invention is to provide a heavy metal zero-discharge treatment sys...
