Electrolytic manganese wastewater ion exchange treatment system adopting aeration type ion exchange devices

Abstract

The invention discloses an electrolytic manganese wastewater ion exchange treatment system adopting aeration type ion exchange devices. The electrolytic manganese wastewater ion exchange treatment system is characterized in that a wastewater storage pond (4) is connected with lower liquid feeding and discharging holes of an ion exchanger A (1) and an ion exchanger B (2) respectively; a regeneration liquid preparation pond (3) is connected with upper liquid feeding and discharging holes of the ion exchanger A (1) and the ion exchanger B (2) respectively; a valve is arranged on a pipeline; both the ion exchanger A (1) and the ion exchanger B (2) are the full-contact aeration type ion exchange devices. The electrolytic manganese wastewater ion exchange treatment system has the beneficial effects that the system operating efficiency is improved, the continuous adsorption of equipment is ensured, a process is realized by controlling the valve to be opened and closed, a control process is simple and stable, a control mode is simple and easy to operate, the adjustment is quick, and the outlet water quality can meet the standard; the full-contact aeration type ion exchange devices are adopted, so that resin can be in full contact with water to be treated and full adsorption is ensured.

Description

Technical field [0001] The invention relates to the technical field of ion exchange devices, in particular to an electrolytic manganese wastewater ion exchange treatment system adopting an aeration type ion exchange device. Background technique [0002] Ion exchange technology has a very wide range of applications in the field of water treatment. Through ion exchange, inorganic salts in water can be removed more thoroughly. Ion exchange equipment is widely used in the fields of medicine, chemical industry, electronics, coating, beverage and high-pressure boiler water supply. 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 standby methods for processing. , Which makes the ion exchange equipment costly and covers a large area. [0003] Most of the ...

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 adsorbed, and the instantaneous value of the effluent will exceed the standard.
