Domestic and municipal sewage treatment plant development survey: urban sewage treatment since the industrial revolution 200 years ago, more and more people's attention. Urban sewage treatment rate has become an important symbol of civilization of a region or not. Nearly 200 years, the urban sewage treatment from natural raw deal, simply to take advantage of a deal with the development of advanced surgery, advanced treatment of wastewater and reuse. Treatment process from conventional activated sludge process, oxidation ditch process development to A / O, A2 / O, AB, SBR (including CCAS process) and other processes of chemical wastewater treatment methods to achieve different water requirements. China's urban sewage treatment relative to developed countries, a late start, the current urban sewage treatment rate of only 6.7%. While we strongly cause foreign advanced technology, equipment and experience sewage treatment must be combined with China's development, especially in local conditions, to explore suitable for China's actual urban sewage treatment system. Precautions centrifugal sewage treatment equipment: Notes sewage treatment equipment centrifugal pump test run: After the unit installation and adjustment is completed, you can test run. Should do the following tasks before the test run: coaxial pump and motor after confirmation hand rotation coupling, empirically feel the severity of their rotation is uniform, any abnormal sound new sewage treatment methods, inspection of pumps and motors have all normal. (For example, after loosening jammed rotating parts, debris blockage, freezing the pump, packing or mechanical seal too tight or too loose, bent shaft bearings in oil and other issues.) Check the power supply system of sewage treatment equipment, power switch, instrument lines and other related equipment is in good condition. Water valve fully open (when the water valve), while closing the outlet valve and pressure gauge, to pump water (such as the use of vacuum valves bottomless water). Loosen the pump cover side bleed plugs urban sewage treatment, exhausted air may remain inside the pump and re-tighten. Re-check the centrifugal pump sewage treatment equipment is intact throughout the bolting. Confirm the water conditions are met (such as feed water height, intake pressure, etc.).
