Filtering device allowing activated carbon to be replaced through automatic program

Abstract

The invention provides a filtering device allowing activated carbon to be replaced through an automatic program.The filtering device comprises an electroplating liquid tank feed pump connected with an electroplating liquid tank, an activated carbon treatment device, a secondary filter, an activated carbon discharge tank, an activated carbon replacing tank, an activated carbon conveying pump, an intelligent control system, a solenoid valve assembly and a pipeline assembly connected with the solenoid valve assembly, wherein the electroplating liquid tank feed pump, the activated carbon conveying pump and the solenoid valve assembly are connected with a control module in the intelligent control system, an activated carbon separator is arranged at the outlet end of the activated carbon treatment device, and the activated carbon treatment device is connected with a pressure display meter.A traditional activated carbon electroplating liquid filtering system is improved, the effect of automatically replacing the activated carbon is achieved, all equipment operation is automatically controlled basically, the filtering device is easy and convenient to use and high in treatment efficiency, the efficiency is remarkably improved compared with an existing scheme of cleaning a filter, and a great deal of pure water for cleaning the filter is saved.

Description

technical field [0001] The invention relates to the technical field of environmental resources, in particular to a filtering device for replacing active carbon with an automatic program, which is suitable for purifying harmful COD produced in on-site electroplating baths, and can also treat organic wastewater with high COD. Background technique [0002] The electroplating cleaning sewage produced in the production of electroplating industry enterprises is a high-concentration wastewater due to its many types of heavy metals, high content, high toxicity, strong acidity, and refractory degradation. standard. In order to further deepen the treatment of the sewage environment in the electroplating industry, starting from October 2014, new standards have been implemented for the polluted water of electroplating enterprises. requirements. [0003] When activated carbon is used for treatment, from the liquid entering the treatment device to the outflow after treatment, most of th...

Problems solved by technology

[0003] When activated carbon is used for treatment, from the liquid entering the treatment device to the outflow after treatment, most of the traditional treatment equipment adopts long-term static precipitation, filter filter element filtration, and undercurrent method. The intermediate process is in a closed state, and the plating solution cannot be observed and tested. It is impossible to make timely adjustments according to the processing situation
