Whole-process automatically controlled electrolytic manganese wastewater ion exchange treatment system

Abstract

The invention discloses a whole-process automatically controlled electrolytic manganese wastewater ion exchange treatment system. A water outlet of a wastewater storage tank (4) is connected with lower liquid accesses of an ion exchanger A (1) and an ion exchanger B (2) respectively, a water outlet of a regenerated liquid distribution tank (3) is connected with an upper liquid accesses of the ion exchanger A (1) and the ion exchanger B (2) respectively, the lower liquid access and the upper liquid access of the ion exchanger A (1) are also connected with a drainage port A (7) respectively, the lower liquid access and the upper liquid access of the ion exchanger B (2) are also connected with a drainage port B (10) respectively, and an electric valve is arranged on a pipeline and electrically connected with a PLC (programmable logic controller). The system has the beneficial effects that the PLC control program automatically runs in the whole process, so that the automation degree of equipment is improved, and the running efficiency of the system is improved; the two ion exchangers arranged in parallel ensure continuous adsorption of the equipment.

Description

technical field [0001] The invention relates to the technical field of ion exchange devices, in particular to an ion exchange treatment system for electrolytic manganese wastewater with automatic control over the whole process. 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 ar...

Problems solved by technology

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. , which makes the cost of ion exchange equipment high and occupies a large area

[0003] Most of the existing devices are operated by manual control or semi-automatic control, and there are many valves in the ion exchange system, and the operation process is cumbersome; the existing devices use online detection equipment to detect water quality to feed back the system for adsorption-regeneration process switching, and online equipment to detect water samples It takes a long time. If the information is not fed back in time and the adsorption-regeneration process is switched in time, the resin will be overloaded and the instantaneous value of the effluent will exceed the standard; existing devices often ignore the automatic control of the regeneration process, and cannot truly realize ion exchange adsorption-regeneration The whole process is automatically controlled; the existing device realizes fully automatic control, and its control parameters are various. The present invention only uses time for automatic control, supplemented by ammonia nitrogen online monitoring as a fully automatic control parameter, and the control method is simple and easy to operate
