Y-type filter sewage treatment each technology has its advantages, the characteristics of the applicable conditions and lack of it is impossible to replace all other processes in a process, and it is not to leave the specific loca l conditions and the condition of our country. The same process in different influent and effluent conditions, access to the different design parameters, the selection of equipment is not static. Reasonable to determine the design of the sewage water and wastewater quality, directly involved in the project investment, running costs and cost-effectiveness. Many cities because of the urban sewers are not forming system, the lack of long-term accumulation of sewage water volume data is generally taken by the planning area, population and industrial development forecast to derive the amount of sewage, and raised the amount of sewage, industrial waste water, and public buildings the respective proportions of commercial quantity of sewage, the more uncertainty, the proposed design volume of sewage is often too great.air filter cartridge

In order to strengthen the urban sewage treatment, protection o f the water environment, the central increase the Y-shaped filter delivery efforts. Existing 668 cities in the country, only 123 cities have 307 different processing levels of urban sewage treatment plants, of which about 10% of secondary urban sewage treatment rate, 17,000 towns across the country, the vast majority did not drain and Y-type filter sewage treatment facilities. Throughout the world, the drainage system and the Y-shaped filter sewage treatment rate, there is a gradual development of and gradually improve the process. Required to achieve 25% of a country to 2000 China s sewage treatment rate reached 40% in 2010, and strive to achieve in all aspects of efforts. In fact, the amount of sewage calculated according to plan and the volume of sewage, the actual amount of sewage collected is different and based on the needs and possibilities for processing sewage, the amount of sewage in the design depends largely on the sewage pipe network penetration and possible to collect the actual amount of short and long term sewage, sewage treatment plant and construction phases.

Y-type filter on the choice of specific engineering requirements include: â'  reasonable. Advanced and mature technology, adaptable to changes in water quality, effluent standards and high stability, easy to handle sludge. â'¡ economic energy saving. Small power consumption, low cost, small footprint. â'¢ easy to manage. Easy operation and management, and reliable equipment. â'£ great importance to the environment. Equipment layout in harmony with the surrounding environment, attention to the factory noise control and odor governance, green, road and phased construction is a good combination. A city, to be based on the overall urban planning and drainage planning stages, the construction of the sewer network and sewage treatment plants, according to the water environmental protection objectives, implemented in phases, gradually put in place. Urban drainage proj ect construction is a systematic project involving the transformation of urban pipe drainage, sewage collection, transportation, use of sewage treatment and disposal, and the Y-shaped filter disposal of sludge and other issues; cities in river networks, the need to consider the upstream and downstream and water self-purification.
