The regeneration water research based on the characteristics of jiangnan water in the green ecological building area

The recycled water is the important way to solve the shortage of water resources. In China the recycled water use in the jiangnan region is still in start level, rare setting up reclaimed water system inside the village. According to designing water system in jiangnan area, using the high quality miscellaneous drainage for raw water, filtering the all sizes of particle in water, and adopting the biological membrane system decompose the organic therein, the water after disinfection can be as the non potable water. This water system is simple in technology, not occupying the land, four years of recyclable cost and the operation maintenance costs are low.
