Electrolytic manganese waste water ion exchange treatment system under automatic control in whole process and adopting aeration type ion exchange device

Abstract

The invention discloses an electrolytic manganese waste water ion exchange treatment system under automatic control in a whole process and adopting an aeration type ion exchange device. The electrolytic manganese waste water ion exchange treatment system is characterized in that a waste water storage tank (4) is respectively connected with lower liquid inlets / outlets of an ion exchange A(1) and an ion exchange B(2), a regenerated liquid preparation tank (3) is respectively connected with upper liquid inlets / outlets of the ion exchange A(1) and the ion exchange B(2), an electrically operated valve is arranged on a pipeline, the electrically operated valve is electrically connected with a PLC (programmable logic controller), and the ion exchange A(1) and the ion exchange B(2) are both full contact aeration ion exchange devices. The electrolytic manganese waste water ion exchange treatment system has the beneficial effects that the PLC controls the program to perform automatic operation in the whole process, automation degree of equipment is improved, and the operating efficiency of the system is improved; two ion exchanges which are arranged in parallel guarantee continuous adsorption of the equipment; the full contact aeration ion exchange devices are adopted to ensure that resin comes into full contact with water to be treated to guarantee full adsorption.

Description

technical field [0001] The invention relates to an ion-exchange treatment system for electrolytic manganese wastewater with automatic control over the whole process and an aeration-type ion-exchange device. Background technique [0002] Ion exchange technology is widely used in the field of water treatment, and the inorganic salts in water can be removed more thoroughly through ion exchange. Ion exchange equipment is widely used in the fields of medicine, chemical industry, electronics, coating, beverage and high-pressure boiler feed water. The exchange resin added to the ion exchange device will fail after the equipment runs for a period of time, and needs to be regenerated, and the system needs to run continuously for 24 hours. Therefore, many domestic ion exchange systems mostly use one set of operation and one set of backup methods. , making the cost of ion exchange equipment high and occupying a large area. [0003] Most of the existing devices are operated by manual ...

AI Technical Summary

Problems solved by technology

At present, ion exchange columns are mostly used, but due to the large mass of resin loaded during use, the resin cannot completely contact the solution, and the resin utilization rate is low; the working state of the resin in the ion exchange device is not balanced, which accelerates the deterioration of the performance of some resins and shortens the time. The service life of the device is shortened; air pockets in the resin bed are generated due to untimely exhaust or unbalanced pressure, which will lead to poor water discharge, increased pressure on the tank body, and increased water head loss; the existing ion exchange resin device, backwashing Due to uneven water distribution, uneven pressure and other factors, the resin bed cannot be effectively loosened, resulting in a decrease in resorption efficiency.
