2. considering the stable and safe operation of the system, the water retaining quantity is at least 4000 cubic (2500 cubic water in the pool and 1500 cubic water in the pipeline), after the system is cleaned, the pre-membrane can be carried out by replacing at least two to three times with water, and sewage generated in the process is at least 10000 cubic. Most of the water after pre-filming needs to be discharged out of the system, and needs to be replaced at least twice, and at least 6000 cubes of sewage are generated in the period;

3. the sewage generated by one-time cleaning of the pre-film reaches 16000 cubic, and the difficulty is heavy if the sewage is directly discharged to a sewage treatment plant.

For this reason, it is desirable to find a better way of treating sewage to reduce the amount of sewage.
