Macroporous adsorbing resin automatic regeneration device

Abstract

The invention relates to a macroporous adsorbing resin automatic regeneration device, which comprises a regeneration resin tank, a spectrograph, a conductivity meter, a blowdown electromagnetic valve, a sewage collecting tank, a regeneration liquid electromagnetic valve, a regeneration liquid storage tank, a backflushing water electromagnetic valve, a backflushing water tank, a control box, a backflushing water guide pipe, a regeneration liquid guide pipe and a water drain pipe, wherein the regeneration resin tank is used for containing macroporous adsorbing; the spectrograph is an online spectrum COD (chemical oxygen demand) detection device, and is used for detecting the COD concentration in real time, and transmitting the data to the control box; the control box is used for controlling the blowdown electromagnetic valve, the regeneration liquid electromagnetic valve and the backflushing water electromagnetic valve. The macroporous adsorbing resin automatic regeneration device has the advantages that the COD concentration of regeneration liquid at an outlet of the regeneration resin tank is detected in real time; meanwhile, the control box can adjust the flow rates of the regeneration liquid and backflushing water according to the concentration, so as to prevent the excessive use of the regeneration liquid and the backflushing water, and reduce the operation cost.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a macroporous adsorption resin automatic regeneration device. Background technique [0002] Chemical oxygen demand (COD) is the amount of oxygen consumed by the oxidation of reducing pollutants in water by strong oxidants, and is an important comprehensive index for evaluating the pollution of water. With the rapid development of industry and agriculture, a large amount of wastewater containing COD needs to be treated. For example, chemical industry, electroplating, and agricultural livestock and poultry houses all produce a large amount of wastewater with high COD content. [0003] In wastewater COD treatment technology, macroporous adsorption resin method has high removal efficiency, simple equipment and easy operation. Compared with activated carbon, macroporous adsorption resin can be regenerated and used repeatedly. However, when the resin is regenerated, due ...

AI Technical Summary

Problems solved by technology

The above-mentioned device cannot detect the content of pollutants in the regeneration liquid at the outlet of the regeneration container in real time, and cannot quantitatively confirm whether the regeneration of the resin is completed. It can only judge whether the regeneration is complete based on the total use time or experience. Excessive use of regenerative chemicals and backwash water, thereby increasing operating costs and poor regeneration effect
