本实验采用小型CASS反应器对某厂的难降解农药生产废水和某厂的合成制药废水进行处理实验研究，重点研究了污泥回流比、进水历时、CASS池各区比例、有机负荷等因素对CASS系统去除废水COD和氨氮效果的影响。

The sewage flows from pool to plant, passing through retention reservoir to adjust PH value, into removing ammonia with temperature increasing to 20℃,into UASB reactor with temperature increasingto 35℃ to remove off COD and ammonia under the function of anaerobia, then into SBR reactor to remove BOD under the function of aerobia. When the biochemical disposal is completed, the processed sewage will come into the UF system to remove adsorbed solid, organic matter, bacteria, and pathogens in waterand finally come into the RO system to remove off dissolvable salinity, colloid, organic matter, and microbe in water.

垃圾渗滤液经储存池进入污水处理厂，经调节池调整PH值，经1#加热器升温到20℃进入氨吹脱塔脱氨氮，再经2#加热器升温到35℃进人UASB生物反应器，在厌氧菌的作用下降解COD和脱氮，再进入SBR生物反应器，在好氧菌的作用下降解BOD，完成生化前处理后转入UF超滤中空纤维膜系统进行分离处理吸附固体、有机物、细菌、病原体等；最后经高压泵送入进口的RO返渗透中空纤维膜系统中，进行分离处理可溶解盐分、胶体、有机物、微生物等。

If Sequencing Batch Reactor was used directly to treat anaerobically digested effluent, the treatment efficiency was very poor, with only 8.31% for COD removal rate, and 78.7% for NH 3 N.

采用序批式活性污泥法工艺直接处理厌氧消化液，污染物的去除效果很差，COD仅去除8.31%，NH3-N去除7 8.7%。

Results showed that internal electrolysis pre-treatment of yeast-producing wastewater were effective on the removal of COD and colority.What is more important is that the biod...

The purpose of this technical bluebook is to 1 provide background information on oxygen demand testing, and 2 discuss the comparative advantages of methods currently available, including the new Hach Manganese III COD Method designed to eliminate hazardous heavy metals waste.

而这份技术报告的目的在于：1）提供测需氧量的背景信息，2）讨论现在流行方法的优点比较，这当然也包括新的设计以消除有害重金属废物的哈希高锰酸盐III COD方法。

When chloric ion was 8 500 mg/L and salinity was 1.6％,the anaerobic activated sludge could degrade organic materials normally in the wastewater after the acclimation, and the COD removal is over 85％.

在氯离子浓度为8 500 mg/L，含盐量为1.6％，经过驯化，污泥能够正常降解废水中的有机物，COD去除率在85％以上。

The microorganism method to solves the landscape hydrophila group entrophication has the good function,is obviously degenerate the water body COD,also can suppress the growth of the chlorophyceae plant effectively;④Chemistry method maintenance water quality may oxidize effectively, degenerate the pollutant and some organic matter in water,can effective kill the algae;⑤The clear silt can eliminate the death algae and each kind of organic and inorganic substance,thoroughly eliminate the environment which the algae grow,therefore the clear silt to algaes government is the very thorough means.

微生物法对解决景观水体的富营养化有较好的作用，对水体COD的降解作用较明显，能够有效抑制绿藻类植物的生长；④化学方法维护水质可以有效氧化、降解水中污染物和一些有机物质，能够有效的杀灭藻类；⑤清淤能够把死亡的藻类和各种有机和无机物质清除掉，彻底清除藻类生长的环境，所以清淤对藻类的治理是很彻底的办法。
