| At present Aerobic treatment is widely used in Urban Domestic Sewage treatment, such as Activated sludge process, Oxidation ditch and SBR etc. But the expenditure of this treatment is very high which is not suitable for our developing country suffering from the capital. So, the choose of develop the technology which is low cosU low energy demand and simply management is necessity.The text with UASB+ Trickling Filter / Solids Contact Process is the research target, comparing with traditional treatment process ,the costs of construction and operation of it is much lower, the effect is high. And it is a well application foreground in the southern area.The content of the study includes the performance of UASB+ Trickling Filter/ Solids Contact Process for domestic sewage treatment ,the effects of theoperation parameters, switched on the normal temperature, steady operatingcharacteristic, the season operational performance, and the ability of bearing highimpact loads.Result showed that UASB+ Trickling Filter / Solids Contact Process can work steadily,have low sludge production and excellent ability of bearing high impact loads .The general removal rate of COD,BOD5,TP,NH3-N,SS are found to be 84.7%,86.2%,85.8%,82.3%,88.6%. The effluent concentration can up to national primary emission standard of ion standard of sewage (GB8978-1996). |
