With the rapid development of social economy, the discharge of various industrial production wastes and agricultural and animal husbandry compounds has caused significant environmental pollution to water sources, causing water sources to contain various residues, bacteria and viruses. However, most water plants in my country adopt simple sedimentation filtration and traditional tap water disinfection processes, which cannot remove toxic and side-effect pollutants and algae in the water source, and the effluent water body cannot be qualified.
In order to ensure the quality of the water produced, it can be solved in the form of traditional processing +3. According to the basic concrete, sedimentation, filtration and disinfection of the water plant, the ultrafiltration system can basically be improved, the residue can be removed rationally, and bacteria and viruses such as Escherichia coli, flagellates, and phages can be intercepted. Stabilize the produced water body and reach the new standard of municipal engineering drinking water treatment.
1. Detailed introduction of uf membrane use application steps technology
a. Original water storage tank: store water source, used to settle large fine sand particles and chemical substances in the water. At the same time, the impact of unstable pressure of the original pipeline on ultrafiltration water filter is buffered;
b. Adding coagulant and sedimentation: Large suspended solids are easy to precipitate under the action of heavy capacity, while tiny floating particles and colloidal solution residues can indeed keep separated and float in the water for a long time, making the water turbid. The function of concrete is to condense the fine particles into solid particles to facilitate precipitation;
c. Activated carbon filter: Select an activated carbon filter to absorb point-degraded positive ions for ion exchange absorption. In addition, because the adsorption function increases the content of the surface being adsorbed and replicated, it has a catalytic reaction and rationally removes the melanin and odor in the water. Many biochemical organic compounds and other pollutants;
d. Add disinfectant: eliminate germs and harmful microorganisms in the water;
e. Ultrafiltration system filtration: rationally remove residual residues in the water and hydrogen generated by disinfection, intercept bacteria and viruses such as Escherichia coli, flagellates, and use water to specify domestic water purification treatment index values.
2. Advantages of using uf membrane use in water plants
a. It can fully remove germs, algae, and virus infections in the water environment, and ensure the safety factor of microbial strains in domestic water;
b. Can greatly reduce the total output of disinfection by-products;
c. The effluent body is stable and adaptable, and the turbidity of the produced water is stable below 0.1NTU;
d. The controllable module construction of the water plant, the expansion project is very easy, and the construction period is short.
Three, the main purpose of uf membrane use
For water plant construction, reconstruction, water plant upgrade, expansion, transformation, expansion, water plant production, manufacturing, sludge recovery, municipal engineering domestic water purification treatment, etc.
