Based on the experience of McCartyi of the U.S.and Chen Ru-chen of China,u-sing an improved up-flow anaerobic filter of 10 litres,we have succeeded in the treatment of the waste water produced in making fatty acids.The filter is made of organic glass.The temperature of the treatment is 35℃ The detention time is one day.Investigations have been made on the cultivation conditions of the organism,the influence of the pH value and the organic load on the gas production,and the relationship between the organic load and the COD removal rate of the waste water.The strain in the filter cultivated with a proper culture medium can maintain its high ability to digest organic matter in the waste water in more than a month.Its gas production rate has risen from 0.2m3/m3.day to 2.8m3/m3.day.When the organic load in the waste water goes up from 5g/l to20g/l,the gas production rate increases sharp from 3.3m3/m3.day to 9.5m3/m3.day.The proportion of methane in the bio-gas produced is normal.The extra-COD removal rate in the waste water still can be maintained at 70 per cent.What's more important is that the pH value of the influent is always below 5.0 and that of the effluent is neutral.We have also studied the relationship betweem the COD removal rate in the waste water and different height of the filter.

The experiment of fhe fluid waterfilm which in rotation the biomass on the contactor carries into the air has proved that waterfilm is treated considerably well in a few or several ten seconds. At a organic loading of approximately 9.2g/m~2.d, in a three-stagesystem, it is apparent that the BOD_5-Value of the first stage-waterfilm is always lower than that of the second stage effluent, and only a little higher than that of the third stage effluent. Compared with the first stage-waterfilm, up to 35% of COD is removed from the same stage tankwater. In the third stage nitrification process the waterfilm also has a higher NH_4 removal and Nox/N percentage than the same stage tankwater. The NH_4 removal from the third stage tankwater is like the COD removal from the first stage tankwater, i.e. 35% also. The removal of the contaminant and the waterflow which biomass has carried, depend on the biosurface form and structure and rotational speed of the biological contactor. The shaggy biosurface with many macroscopic filaments is more effective than without them. While the rotational speed of the biological contactor slows down, the carried waterflow slows down, too, and the waterquality becomes more better.

通过对旋转生物转盘生物膜表面上形成的流动水膜的本试验研究,清楚地证实了,在十几秒到几十秒的极短时间内此水膜已得到相当好的处理。在有机负荷BOD_59.2克/米~2天时,一个三级转盘系统,其第一级盘上水膜的BOD_5值始终低于二级出水,只比三级出水BOD_5值略高些。与同级槽水比较,该水膜COD平均减少35%,在第三级硝化过程中,其水膜的氨氮去除率和N_(ox)/N百分数也比同级槽水高得多,其氨氮减少情况类似第一级的COD,即也在35%左右。生物膜携带的膜水量和其对污染物的去除程度与生物膜的形状和构造及转速等有关。具有较明显的毛状生物膜比一般无毛的凹凸膜效果要好。转速减少时,携带水量有所下降,但膜水水质变得好些。本试验还证实了,水膜不仅迅速从空气中吸收氧,而且由于迅速将水中CO_2吹脱到空气中而使水膜PH值有所提高。
