Investigate On Current Situation Of Rural Domestic Sewage&waste And Treatment Technology Selection

Along with the rural economy make a spurt of progress, the integration of urbanand rural areas continue to advance, rustic appearance and the farmer living standardhas undergone changes can turn the world upside down, but the problem such asenvironmental pollution is not optimistic. In particular, rural domestic sewage and wastelead to water, atmosphere, soil pollution, and serious pollution damage on the ruralecological environment, make rural environment problem increasingly become a focusin China’s environmental protection work, has already aroused the attention fromvarious circles of society.This topic through the method of combining select typical farmer, generateemission investigation, continuous sampling survey, field analysis and laboratoryanalysis, to master the system of rural domestic pollution emission characteristics. Onthis basis, analysis the treatment technology of domestic sewage and waste in the studyarea, draw the following main conclusions:â‘ The domestic sewage emission characteristics: domestic sewage emissioncapacity per capita was19.49L/cap·d^-1, pH average of sewage was6.29, concentrationsaverage of COD, TAN, TN and TP in domestic sewage respectively were1360.91mg·L^-1,18.16mg·L^-1,62.51mg·L^-1and6.66mg·L^-1; Domestic sewage contaminantsthat COD, TAN, TN and TP daily capacity per capita respectively were22.967g/cap·d^-1,0.347g/cap·d^-1,1.241g/cap·d^-1,0.119g/cap·d^-1.â‘¡The domestic waste emission characteristics: domestic waste emission capacityper capita was0.328kg/cap·d^-1, domestic waste unit weight was324.01kg/m3, andmoisture content was58.24%. Organic component, recyclable component, harmfulcomponent, other component in domestic waste respectively were56.88%,12.54%,0.42%,30.16%, TN component, TP component, in organic waste respectively were0.90%,0.12%; Organic waste, recyclable waste, harmful waste, other waste, TN inorganic waste, TP in organic waste per capita respectively were0.197kg/cap·d^-1,0.043kg/cap·d^-1,0.002kg/cap·d^-1,0.081kg/cap·d^-1,0.713g/cap·d^-1,0.095g/cap·d^-1.â‘¢The influence between income level and sewage daily generation per capita wassignificant. The influence between income level and COD, TAN, TN, TP daily capacityper capita in domestic sewage was not significant. The influence between income leveland waste, TN, TP daily generation per capita was not significant. On this basis, this topic makes a analysis of treatment countermeasure of domesticsewage and waste in the study area, conclusions are as follows:â‘£This topic combines of rural domestic sewage emission characteristics and ruraltechnical and economic conditions, puts forward: Individual farmer should adopt thefermentation clarification pool/anaerobic biological contact pool/digesters treatingprocess;2¹0inhabited farmers should adopt the small even door anaerobic pondprocess;11²0inhabited farmers should adopt the anaerobic biologicalcontact&waterfall aeration channel process;21³0inhabited farmers should adopt theanaerobic biological contact&waterfall aeration channel&artificial wetland treatmentprocess.⑤This topic also combines of rural domestic waste emission characteristics,comparatives analysis by “Unified Collection, Centralized Treatment”,“ClassifiedCollection, Separated Treatment”, and “Situ reduction, Regular Removal”, conclude:“Situ reduction, Regular Removal” domestic waste treatment model is most helpful forrural domestic waste management, this model not only reduces the processing cost, savelandfill land, prolong landfill service life, but also products agricultural value compost,has high rate of resource utilization.
