序批式活性污泥法处理德士古气化废水

采用SBR(序批式活性污泥法)工艺对德士古气化工艺废水处理,结果表明:在碳、氮、磷比例理想的情况下,达到了既去除有机物又能脱氮的效果。当总停留时间控制在5～9 h、污泥负荷为0.41～0.96 kg BOD5/(kgMLSS.d)时,出水BOD5浓度为0～30 mg/L,去除率达88%～89%;出水COD浓度为10.7～32.2 mg/L,去除率达87%～89%;出水NH3-N浓度为2.83～9.23 mg/L,去除率达95%～97%。

Wastewater Treatment of Texaco Coal Gasification by Sequencing Batch Reactor

By the use of Sequencing Batch Reactor（SBR） to deal with the Texaco coal gasification wastewater,the result showed both of the organic and the nitrogen can be well removed with a good proportion of carbon,nitrogen and phosphorus.When the charge of sludge keeps 0.41~0.96 kg BOD5/（kgMLSS·d）,with the time of sedimentation 5~9 h,the water concentration of BOD 0~30 mg/L,the removal rate reached 88%~89%,COD removal rate can reach 87%~89%,water concentration of COD was 10.7~32.2 mg/L,as well as the removal rate of ammonia nitrogen was 95%~97% with a concentration of 2.83~9.23 mg/L.
