Streams sources dispersed by living sewage pool from remote residents ' daily life . The streams source often untreated sewage discharged into the environment , into the river , pollute the rivers . Currently , the governance of the stream source technology ecological ponds , artificial wetlands . In order to better governance streams source , the combined process of the hydrolysis acidification artificial wetlands . This test focuses on hydrolysis acidification pretreatment effect on the stream source , and to examine the impact of HRT, fillers , and trace amounts of dissolved oxygen . Streams sources and sewage sewage analog test , by the intermittent aeration contrast investigated trace amounts of dissolved oxygen on the hydrolysis acidification on the part of the reactor by adding two different filler ( a combination of fillers and homemade filler ) compared of visits filler treatment effect ; the influence ; trial set five different HRT (4h , 6h , 8h , 12h , 24h) , were investigated under different HRT the hydrolysis acidification of pollutant removal effect . The test results show that : the hydrolysis acidification of COD, SS has better treatment effect , which has a packing 1 ( a combination of fillers ) reaction device works best , its maximum removal of COD and SS in the HRT at 24h , 67.77% and 96.03% , respectively . Certain removal rate of the hydrolysis acidification of TP , which has a better packing 2 ( homemade filler ) , reactor phosphorus and relatively stable , the highest removal efficiency of 27.70% . The hydrolysis acidification nitrogen hardly removal. The test also examines the impact of HRT, traces of dissolved oxygen , packing . Found COD , SS removal effect overall with increasing the HRT increases , while the removal of TP HRT shorter better ; the presence of trace amounts of dissolved oxygen will reduce the effect of the SS removal , increase the COD and TP to In addition to the effect of the combination treatment effect filler greatest impact ; presence of filler to improve the pollutant removal efficiency , including a combination of fillers to promote COD removal of SS , homemade packing TP removal better .
