Combined with China's actual situation, with reference to foreign advanced technology and experience, the construction of urban sewage treatment plant shall comply with the following directions: total investment, our country is a developing country, funding economic development is very large, and therefore strictly control the total investment great benefit to the national economy. Low operating costs, operating costs are an important factor in whether the normal operation of the sewage treatment plant is one of the key indicators to judge the merits of a process. An area of ??the province, China's large population, the per capita land resources is extremely scarce. Land resources is an important factor in many of our urban development and planning. Nitrogen and phosphorus removal. With the eutrophication of large water body environment, nutrient removal wastewater has become a pressing issue. China's latest national implementation of the "Integrated Wastewater Discharge Standard" (GB8978-1996) is also clear that the phosphate emissions standards and ammonia emissions standards apply to all sewage disposal units, very strict regulations. This means that in the future the majority of urban sewage treatment plants have to consider the problem of nitrogen and phosphorus removal. Combine modern advanced technology and environmental projects. Modern advanced technology, especially the emergence of computer technology and automatic control system equipment and perfect for the development of environmental projects to provide a strong support. Currently, foreign countries, most sewage treatment plants and the use of advanced computer-controlled system Taiyuan environmental management company address, to ensure the normal operation of sewage treatment plant effluent and stable qualified environmental District Address, while China is still relatively backward in this regard. Computer control and management will also be the direction of China's urban sewage treatment plant development. Reflux pump the sewage treatment process composition and maintenance: single-stage centrifugal pump sewage treatment pump Tianli environmental companies including addresses, pump cover, with the output shaft of the motor installed in the pump body of the pump shaft, bearing, impeller, mechanical seal and mechanical seal gland, characterized in that it comprises setting located between the motor output shaft and shaft couplings for clip-on, as well as auxiliary support shaft guide bearings installed in the sewage treatment bearing seat. Sewage treatment clamp couplings respectively motor output shaft and shaft rigid connection between the motor output shaft and shaft leaving facilitate mechanical seals and gland of assembly and disassembly of spatial distance. When the repair or replacement of mechanical seals, without removing the motor and pump cover. Sewage attention when using a single-stage centrifugal pump, to avoid shaft wear, at the site of the shaft through the packing chamber is equipped with protective sleeve, quasi O-ring between the sleeve and the shaft to prevent along with the surface of the intake or leaks . Sewage single-stage centrifugal pump drive is through lengthened flexible coupling with the motor connected, the direction of rotation of the pump from the drive end address environmental companies, clockwise rotation.
