Precision integrated treatment management system for electroplating wastewater and its realization method

Abstract

The invention discloses a precise comprehensive treatment management system for electroplating wastewater, which includes a front-end regulation unit, a wastewater treatment unit, a monitoring unit, and a control terminal. Treatment and biochemical treatment, the control terminal controls the wastewater that does not exceed the standard to be discharged into the corresponding collection pool, the wastewater that meets the standard is discharged into the biochemical pool, and the qualified supernatant is discharged back to the factory area. The present invention also provides a method for realizing the precise comprehensive treatment management system of electroplating wastewater; the present invention realizes the quality-based collection and classified treatment of electroplating wastewater in each workshop, realizes automatic and intelligent control in the whole process, and greatly reduces the treatment cost.

Description

technical field [0001] The invention belongs to the technical field of electroplating wastewater treatment, and in particular relates to an electroplating wastewater precise comprehensive treatment management system and an implementation method thereof. Background technique [0002] Electroplating wastewater is mainly discharged from electroplating factories or workshops. Due to many types of plating and cumbersome processes, its water quality is complex and its composition is difficult to control. Electroplating wastewater mainly contains heavy metal ions such as phosphorus, nickel, copper, and cyanide. These electroplating wastewater are carcinogenic , teratogenic, mutagenic highly toxic substances, direct discharge will cause great harm to the environment. [0003] The existing treatment methods of electroplating wastewater are generally for one of the above-mentioned ones. The wastewater treatment technology mainly includes three parts: electroplating wastewater collecti...

[0002] Electroplating wastewater is mainly discharged from electroplating factories or workshops. Due to many types of plating and cumbersome processes, its water quality is complex and its composition is difficult to control. Electroplating wastewater mainly contains heavy metal ions such as phosphorus, nickel, copper, and cyanide. These electroplating wastewater are carcinogenic , teratogenic, mutagenic highly toxic substances, direct discharge will cause great harm to the environment

[0003] The existing treatment methods of electroplating wastewater are generally for one of the above-mentioned ones. The wastewater treatment technology mainly includes three parts: electroplating wastewater collection, wastewater pretreatment and wastewater biochemical treatment. Different treatment methods or devices are often designed for different types of wastewater. Processing, unable to carry out intelligent system control processing, high cost and low efficiency

[0004] For example, in Chinese patent 201110431946.X, a method for treating electroplating wastewater containing heavy metals and recycling heavy metals, the steps are: passing the low-concentration electroplating wastewater containing heavy metal ions through an ion exchange resin to completely remove the heavy metal ions contained in the electroplating wastewater Adsorbed on the ion exchange resin and separate clean water until the adsorption of the ion exchange resin reaches saturation, adding an eluent to separate the heavy metal ions adsorbed on the ion exchange resin from the ion exchange resin to produce high-concentration electroplating wastewater, and then to high Concentration electroplating wastewater is added with a reducing agent for reduction reaction to obtain insoluble reduction products containing heavy metal ions, adding flocculants to speed up the coagulation of the reduction products, and finally the precipitates are separated by filtration or centrifugation, and heavy metals are recovered by high-temperature calcination Substances are useful industrial raw materials; however, the whole process of the present invention cannot realize accurate classification and collection first, and then classification treatment, especially in the wastewater treatment and recycling of multiple electroplating workshops in large-scale factory areas, the efficiency is low, and automatic feedback information, independent monitoring and control process
