【 摘 要 】

In order to solve the problem of high-salt ballast wastewater treatment, Sequencing Biofilm Batch Reactor of new packing activated sludge process used to simulate an experimental study. When Chloride ion concentration is 202g/L, the impacts of reaction period and anoxic time (Ta) / aerobic time (To) on the effect of the treatment process and sludge activity were investigated. The results show the salt acclimation SBBR process can effectively remove organic contaminants; when the reaction period was 49h, the removal rates of Chemical Oxygen Demand (COD) reached more than 91.0%, and the removal rate of NH+ 4 -N was 83.3%, the removal rate of Total Nitrogen (TN) was 67.7%, and the effluent concentration of COD, NH+ 4 -N and TN were respectively 45.7mg/L, 7.8mg/L and 18.6mg/L. At this time, TF reached 43.6pg/ml. With the Ta / To increase, the degree of denitrification increased and the nitrification rate reduced. When Ta/To 1:3, the optimal nitrogen removal appeared, ammonia removal efficiency was 83.8%, the effluent concentration was 7.8mg / L, TN removal rate was 67.7%, and the effluent concentration was 18.6mg / L, to reach effluent standards. Technical support was also provided to solve the problem of coastal salt waste low phosphorus wastewater.
