| titleOfInvention | Treatment method of human waste and septic tank sludge |
| abstract | (57) [Summary] [Purpose] A rational treatment to obtain treated water from which BOD, COD, nitrogen, phosphorus, chromaticity, etc. have been highly removed by the mixing treatment mainly with septic tank sludge and human waste. The purpose is to provide a system. [Structure] After mixing septic tank sludge more than twice as much as human waste, it is dehydrated by adding an inorganic coagulant and a polymer coagulant, and the resulting dehydrated separated water is subjected to biological nitrification / denitrification treatment. . [Effects] By mixing septic tank sludge more than twice as much as human waste, phosphorus can be insolubilized by an inorganic coagulant, and 90% or more of phosphorus contained by dehydration treatment can be insolubilized and removed. become. Therefore, it is possible to obtain the treated water from which the phosphorus is highly removed by the rational treatment without providing the coagulation separation step after the biological treatment. Effects such as improvement of dehydration efficiency and reduction of load on biological treatment or subsequent steps are also exhibited, and a low water content dehydrated cake and high-quality treated water can be efficiently obtained. |
