Abstract:

The general existing low temperature problem in winter of north-city sewage treatment plant in the process of waste water treatment seriously affect the efficiency of the work. The research objective of this paper is to conduct investigate in the application of AICS method in Jilin Province, a sewage treatment plant engineering example has been employed to monitor the effluent of the indicators of sewage treatment under the low temperature condition during the winter the winter low temperature under the condition of sewage treatment plant effluent of the indicators; to understand the operation situation of sewage treatment plant, and to study the efficiency of hydrolysis - AICS processing waste-water. The result shows that: hydrolysis - AICS process works well in low temperature condition, the per TN removal rate is 76.79%, average removal rate of NH3 - N is 85.76%, average TP removal rate was 93.4%, the average COD removal rate was 90.6%. The effluent meet the national level A discharge standard requirements of "urban sewage treatment plant pollutant discharge standard". And through the retrenchment of the second pond and other ancillary equipment, Hydrolysis-AICS process could efficiently reduce the costs. Besides, the advantages of Hydrolysis-AICS process also include occupying small area, and operating easily and simply. Therefore Hydrolysis-AICS process is very helpful to achieve the sewage discharging standard in the northern towns.
