The design of sewage produced by The ********* for processing, to make it up to the standard of water reuse water quality requirements,according to actual condition, to eventually achieve the goal of saving water and wastewater reuse. This design according to the graduation design of ****** “******** Feasibility analysis of water reuse” in the parison of the advantages and disadvantages of various treatment processes, because the advantage of the CASS technological process is simple, cover an area of an area small, low investment, so we finally choose the CASS process as the main processing the process of grating, horizontal flow grit chamber, pre aeration basin, pump room, disinfection, and gray water recycle pool aand the equipment to carry on the design calculation and selection, draw the plane and vertical arrangement.
