Development of ceramic membranes inorganic ceramic membrane also called GT membrane is asymmetric membrane inorganic ceramic materials prepared by a special process, the tubular or multi-channel shape. Dense ceramic membrane wall micropores, the integration of the device in the water treatment under pressure, the raw material liquid in the membrane tube or the outer membrane fluidity household water treatment equipment, small molecules (or liquid) through the membrane, macromolecules (or solid particles, liquid droplets) retained by the membrane so as to achieve a solid-liquid separation, concentration and purification purposes. In the field of membrane science and technology development and application of the earlier organic film, this film is easy to prepare, easy to shape, good performance, low price, has become the most widely used type of microfiltration membranes. But with the development of membrane separation technology and its applications, the conditions for the use of films made increasing demands extreme conditions require developed a solid-liquid separation membrane system, and the organic film, compared with a high temperature ceramic membrane , good chemical stability, acid and alkali resistant to organic solvents, high mechanical strength, can reverse flush, anti-microbial capability, washable and strong, narrow pore size distribution, penetration of large water treatment equipment, membrane flux high, good separation performance and long service life. Inorganic ceramic membrane application in water treatment biggest obstacles are mainly two aspects, one is the manufacturing process is complicated and costly, expensive; the second is the flux problem, only to overcome the membrane fouling and improved filtration flux membranes, in order to truly promote the application to various fields of water treatment. Urban rainwater utilization, regulation by soil infiltration and surface (including the roof) runoff regulation, implement rainwater resources, thus enabling the hydrological cycle toward the direction of city life in favor of the development. There are several aspects of urban rainwater utilization functions: (1) water-saving features. Using rainwater for toilet flushing, sprinkling the road, watering the lawn, water features water, even for circulating cooling water and fire water, water reuse, saving the city water; (2) Water and ecological restoration capabilities. Strengthening rainwater soil infiltration increase soil moisture, and even enhance the use of rainwater recharge groundwater level, can improve the water environment and the ecological environment; (3) stormwater regulation. Increase soil infiltration of rainwater and stormwater runoff storage will reduce the flow into the stormwater system excluded, thereby improving the reliability of the city's drainage system, reduce urban flooding.
