The results of toxicity experiments showed that R32 would not cause acute, chronic, cumulative and genetical toxicity effect on algae, Allium cepa, Zebra, fish and mice before it absorbed Cr. The recovery and sterilization measurement in routine water treatment could reduce most of the R32 in effluent. This may ensure that the effluent would not cause any ill effect on all kinds of biology in the environment after it was discharged into the river.

After 2 hours, the effluent was still feculent. Once formed, the dynamic membrane would be so firm that it was hardly affected by the shock loading of flux. When the flux was 112.5 L/(m~2·h), no SS was found in the effluent at all.

动态膜在少数情况下会发生&泄漏&的情况，说明动态膜对SS的截留并没有固定膜那么&万无一失&，目前只能推广应用于一些对出水水质要求不是很高的场合。

The exothemicity of impregnated catalyst is not only little in air, but exothemicity is little and heat is dispersed during sulfurization. H2S concentration is much higher in effluent gas, if the effluent gas could be recycled, then sulfiding degree of catalyst is increased and resource is saved.

浸渍催化剂不仅在空气中保管时放热温升小，而且硫化时放热少且分散；尾气中H_2S浓度较大，如果能循环利用尾气，那么既能提高催化剂的硫化度又能节省能源。

Strong alkaline PS resin is first turned to the form of Cu-CL complex ions, and then free and complex cyanides in effluent could be removed effectively through ion exchanger and co- mplexation, with a result of CN~- content in effluent.5mg/L and Cu~(2+)mg/L, which conform to the requirements of discharge regulations.

将通常的苯乙烯强碱树脂先转变成铜氯络离子形态，利用离子交换和络合反应可有效地去除废水中游离的和络合的氰化物，使处理后的废水中氰离子含量小于O.5mg/L，铜离子含量小于1mg/L，达到了排放要求。

The optimal desalinating process based on the following condition: desalination was optimized at effluent pH 4.0, flow volume 4 BV/h. Under these conditions, the volume ratio of resin and effluent in which the concentration of Na+was less than 30mg/L was about 1:6,and the loss rate of malic acid was 18.94%.

最佳上柱条件为：pH4.0的果酸废液，体积流量选择为4 BV/h，Na+浓度低于30mg/L的料液与树脂体积比约为6：1，苹果酸损失率为18.94%。

The phosphorus removal experiment implies the increasing 100 mg/L MLSS concentrations can remove about 1 mg/L TP. The phosphorus removal efficiency can be improved by the increasing rate of MLSS concentrations. When everyday increasing rate of MLSS concentrations are about 500mg/L, the phosphorus removal efficiency would higher than 90%, effluent TP would be lower than 1 mg/L. When MLSS concentrations are fluctuating, effluent phosphorus would fluctuate correspondingly. Everyday the amount of discharging excess sludge can be prejudged by the amount of influent TP.

通过对反应器的除磷效果的研究，发现污泥浓度增长100 mg／L能去除将近1 mg／L TP；发现随着污泥浓度增长速率的增加，除磷效率相应提高；当污泥浓度的增长速率增加到每天500 mg／L时，磷的去除率将高于90％，并且出水TP浓度将低于1 mg／L；发现每天排放的剩余污泥量可以根据进水TP浓度来决定；发现最佳好氧与厌氧时间比T_是0.5；溶解氧冲击指数DO_I被首次提出，作为分析溶解氧DO影响的指标。

It takes about 50d for full-scale anoxic variable rate biofilter with microbe-catalyzed media to finish start-up at 22~28C. When influent flow varies between 485~737m3/d and HRT of biofilter between 7.7~5.0h (HRT of media layer between 3.9~2.6h), effluent COD is below 120 mg/L, SS is below 30 mg/L, and some of effluent BODs is slightly above 30 mg/L (the probability is about 40%) at normal temperature of 17~27C.
