Energy-saving ultrafiltration system control method and ultrafiltration system

Abstract

The disclosure relates to the technical field of sewage treatment, in particular to an energy-saving ultrafiltration system control method and an ultrafiltration system. The control method includes starting the ultrafiltration system; monitoring and judging the liquid level in the water inlet pool, when the liquid level in the water inlet pool is greater than the first preset value, the liquid in the water inlet pool is discharged into the ultrafiltration water inlet pipeline, and the monitoring and recording The change value of the liquid level in the water inlet pool; calculate the average flow difference; adjust the filtration flow to reduce the liquid level change in the water inlet pool. In the method provided by the present disclosure, the time required for the filtration flow to reach the preset value and the change value of the liquid level in the water inlet pool are monitored, so as to obtain the average flow difference in the water inlet pool, and the water inlet flow rate of the water inlet pool is reduced by adjusting the filtration flow rate The difference between the water flow rate and the outlet water flow, thereby reducing the liquid level change of the water inlet pool, making the liquid level of the water inlet pool relatively stable, ensuring continuous filtration of the filtration membrane group, reducing water consumption during shutdown and flushing, and reducing water production costs. Realize system energy saving and consumption reduction.

Description

Technical field [0001] The present disclosure relates to wastewater treatment technology, and particularly relates to an energy-saving control method, and an ultrafiltration system ultrafiltration system. Background technique [0002] During treatment, particularly in relation to water when mentioned standard transformation are common UF membrane separation process. However, membrane systems typically run with variable level, constant flow, constant backwash method of operation timing of accumulation. When the flow rate change is large inflow, into the ultrafiltration tank large level changes, in this method of operation, it will lead to frequent starts and stops ultrafiltration system with filter backwash, backwash water resulting in unnecessary consumption, increased operation energy consumption, and not conducive to a good and stable equipment operation and maintenance. Inventive content [0003] In order to solve the above problems, or at least partly solve the above problem...

AI Technical Summary

Problems solved by technology

When the flow of incoming water changes greatly, the liquid level of the ultrafiltration inlet pool changes greatly. Under this operating method, the ultrafiltration system will be frequently started and stopped for filtration and backwashing, resulting in unnecessary backwashing water consumption and increased The energy consumption of the system operation is not conducive to the good and stable operation and maintenance of the equipment
