There are two filtration methods of flat ceramic membrane, which are positive pressure terminal filtration and negative pressure suction filtration. Positive pressure terminal filtration carries out positive pressure through external pressure; bottom aeration can be used to reduce membrane surface pollution during filtration. The negative pressure suction filtration is the negative pressure formed to carry out the negative pressure suction filtration by the vacuum pump; when filtering, the bottom can be aerated to reduce the membrane surface pollution.
The content of organic matter, ammonia and nitrogen is high in domestic sewage, and the sewage also contains synthetic detergent, bacteria, virus, parasite eggs, etc. According to the characteristics of the sewage quality, the domestic sewage treatment equipment adopts the high-precision separation of flat ceramic membrane and biological treatment, and realizes the separation of mud and water by using the high-precision interception effect of flat ceramic membrane. The retention rate of flat ceramic membrane can reach more than 99% to bacteria, viruses and parasites. After treatment, the water quality is stable, clear and has no peculiar smell, and can be reused to realize sewage Resource utilization.
Flat ceramic membrane is a new configuration of ceramic membrane. It is also a non opposite membrane sintered by α-Al2O3 with purity of 99% at high temperature. The upgrading and reconstruction of sewage treatment plant is a highly comprehensive system engineering, involving many disciplines and related departments. Any unreasonable link will affect the project transformation and cause different degrees of losses.
