Description

technical field [0001] The invention belongs to the field of detection methods for ion exchange water production systems, in particular to a method for optimizing the operation of an ion exchanger desalination system that can diagnose the failure end point of an anion and yang bed in real time and obtain a scientific and reasonable regenerant consumption. Background technique [0002] The ion exchange water production system is widely used in various fields of enterprises because of its stable water quality and mature technology. System water consumption is related to raw water quality, and raw water quality fluctuates greatly with changes in external conditions such as seasons and temperatures, which in turn affects the effect of system water production.

The water consumption of the system is related to the quality of raw water, and the quality of raw water fluctuates greatly with changes in external conditions such as seasons and temperatures, which in turn affects the effect of system water production

Since the current unitary ion exchange desalination system usually uses relatively fixed operating data for regeneration, generally adopts the method of monitoring the conductivity of the negative bed or the silicon leakage of the negative bed, and relies on the periodic water production and water production to roughly judge the operating conditions of the system. The defect is that the original operation method cannot fully adapt to the changes in operating conditions caused by changes in the salinity of raw water and system resin conditions, so that the consumption of regenerants cannot be adjusted in time, and the system failure caused by the first failure of the shade bed due to water quality changes cannot be timely adjusted. Effectively control the leakage of silicon in the produced water, which brings great difficulties to normal production activities

[0003] Disadvantages of existing ion exchange water production system operation detection methods: real-time diagnosis is not possible, regenerant consumption control is unreasonable, resource waste, high operating cost, silicon leakage in produced water, large amount of regenerated sewage, high consumption of neutralized regenerated wastewater
