Direct Reuse Technics Research On Municipal Sewage

Aimed at the "blind area" of the municipal reuse water pipeline, this paperpresents a new way named the direct reuse technology of wastewater from municipalsewer, that is to say, to intercept wastewater in the municipal wastewater pipeline andto treat and reuse it on the spot. Considering the characteristic of the sewage from municipal sewer, this papermainly researchs how to intercept wastewater and treat it to the virescence demand inthe water quality standard of municipal sundry water. The main content concludes twoparts, one is to examine the feasibility of intercepting wastewater in municipal sewer;the other is to research wastewater treatment appliance which has the trait ofminiaturization, stable run, easy operation and convenient manage. In this paper we presents the interception project of wastewater. we know themunicipal sewage's water quality trait through looking up data, study and test. Then,we choose the treatment technology according to the wastewater qualitycharacteristics. After that, based on studying the main reactor, the operation parameterand condition of each unit are confined through the enlarged experiment. Last, thedynamics of the reactor developed by ourselves is studied and it gives much help tothe productive design. The results indicate that the technology can meet the need thatmunicipal sewage reuse to virescence, and the technics is feasible. The application of the technics can reduce the build cost of the long pipeline ofreuse water, and especially it has practicality value in the area where there is greenbeltbut no irrigated water. Additionally, the application of the technics makes up the shortof water resource in much extent and reduces the pollute load of the water body, so ithas definite environmental, economic and social benefits.
