The invention discloses an intelligent control system of processing of electroplated chrome plating waste water. A problem is solved that the environment is damaged caused by the fact that the discharged liquid still contains Cr6+ since it is difficult to control the Cr6+ in the discharged liquid. The system is characterized in that the system comprises a main control terminal, an original liquidcollection module, an original liquid transportation module, an acid liquid transportation module, a reducing agent transportation module, a first reaction module, a second reaction module, and a liquid discharging module; a first reaction reference signal and a second reaction reference signal are preset in the main control terminal; when the first reaction signal is larger than the first reaction reference signal, transportation is achieved through the acid liquid transportation module; and when the second reaction signal is larger than the second reference signal, transportation is achievedthrough the reducing agent transportation module. According to the invention, by controlling the acid liquid and the reducing agent, processing ability for the original liquid is improved; the systemis quite intelligent; and pollution to the environment is reduced.
Description
technical field [0001] The invention relates to a waste water treatment system, in particular to an intelligent control system for electroplating and chrome plating waste water treatment. Background technique [0002] When the product is processed in the factory, a large amount of wastewater will be generated, and the wastewater discharged from the factory workshop needs to be discharged. [0003] In the process of discharge, it is necessary to filter the discharged liquid to reduce the pollution to the environment, but in the process of treating the discharged liquid, it is usually necessary to add other reagents for neutralization in order to discharge the qualified liquid , thereby reducing environmental pollution. [0004] In the prior art, there is a large amount of Cr in the wastewater discharged from the factory workshop 6+ Therefore, it needs to be reduced by acidic liquid and reducing agent, so that Cr 6+ Convert to Cr 3+ , and conduct reasonable discharge. How...
