Domestic and municipal sewage treatment plant development survey: urban sewage treatment since the industrial revolution 200 years ago, Jinshan address environmental companies, 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 technology) and other technology, 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 sunshine environmental company address, must be combined with China's development, especially local environmental companies address the actual situation, to explore suitable for China's actual urban sewage treatment system. Sewage pumps with design principles: Sewage pumps designed to consider acid, alkali corrosion, motor housings, pump housings and coupling device to have a reliable anti-corrosion measures. Design and construction of sewage treatment pump should have a certain foreign body capacity, and not because of urban sewage, sludge and other common rag fiber material and cause blockage or wound, pump flow rate does not drop the long run. Sewage pumps should be able to automatically and securely coupler connection, and the pump should be able to at least two parallel guide rods from the pump pit at the top of the boot to the coupler slide freely. Stir the bottom end of a pump sediment unit. Sewage pump unit and the coupler should be completely sealed metal to metal contact, and do not accept film, O-ring seal or gasket in the form of drainage, the full weight of the pump / motors to bear Changsha environmental Address drain trap by the pump No part of the pump / motor is not in direct contact with or on the pump and pump bearings Bottom plate Bottom plate. Pump and motor are the same production equipment manufacturers and providers. Sewage pump motor must be sufficiently rated power, when the pump is running at any point on its characteristic curve, the motor is not overloaded. Sewage Pump "HQ" tangent at any point on the characteristic curve, which should be directed along the tangent direction of increasing the flow rate decreases the maximum flow rate from the closed to the runtime.
