  influent
The results showed that when acetate was used as the sole carbon resource in the influent, the sludge acclimatized under anaerobic/aerobic operation had good phosphorus removal ability.
      
Under deficient influent alkalinity, when compared to OAA, the AAA process improved treatment efficiency and effluent quality with NH4+-N in the effluent below the detection limit.
      
If the lack of alkalinity in the influent was less than 1/3 of that needed, there is no need for external alkalinity addition and treatment efficiency was the same as that under sufficient influent alkalinity.
      
Even if the lack of alkalinity in the influent was more than 1/3 of that needed, the AAA process was an optimal strategy because it reduced the external alkalinity addition and saved on operational cost.
      
The results showed that NPEOs and its metabolites existed in all the samples of the influent, effluent, and sludge.

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.

我们采用经过改进的、体积为10升的上流式厌氧过滤器,对以石蜡为原料用氧化法制取脂肪酸时排放的酸性有机废水处理进行了研究。试验表明,在35℃下采用适宜的培养基进行菌种驯育,经二个多月就可使菌种具有较高的处理能力,产气率由初始的0.28米~3/米~3·天提高到2.81米~3/米~3·天。当废水的有机负荷从5克/升·天逐渐增至20克/升·天时,产气率也相应由3.3米~3/米~3·天提高至9.5米~3/米~3·天,所产沼气中甲烷含量在60%以上,热值稳定在5000千卡/米~3。 废水在过滤器中滞留时间为1天,COD去除率可达70%,该装置已运转了10个月,未发现堵塞现象。 本研究中废水进料时pH值控制在4.5左右,而出料的pH值仍能维持在中性范围。当过滤器的高与直径的比值为2时,处理效果较好。

It was effective applying acidic hydrolysis to the treatment of omethoate waste-water under Lower pressure. Almost 51-55 percent and 76-82 percent of phosphorous in a crude and synthetie ester influent were transformed from a state of organic into inorganic compound respectively . Then the hydrolyzed liquid was treated by the addition of enough lime milk to pH 9 and a complex precipitated calcium phosphate was obtained. The total removal of phosphorous from influent including inorganic and organic amounted to more than 85 percent. For example, the influent containing organic phosphorous 126.2, COD 266000 and BOD 93800 was reduced to 10.95 g/l 82300 mg/l and 70000 mg/l respectively. The precipitate can be used as a fertilizer, the application of the dried Product to the paddy bowl gave increased crops.

In the paper, two different processes, granular activated carbon adsorption ("C"process) and Ozonation-activated carbon adsorption ("O_3 + C"process), were studied experimentally for removal of three forms of nitrogen from potable water on a comparative way. The results indicate that the ozonation is capable of oxidizing organic nitrogen into NH_3-N, and NO_2~--N into NO_3~--N, thus resulting in the increase of their content in the effluent. It was also found out that the ammonium nitrogen was effectively removed...

In the paper, two different processes, granular activated carbon adsorption ("C"process) and Ozonation-activated carbon adsorption ("O_3 + C"process), were studied experimentally for removal of three forms of nitrogen from potable water on a comparative way. The results indicate that the ozonation is capable of oxidizing organic nitrogen into NH_3-N, and NO_2~--N into NO_3~--N, thus resulting in the increase of their content in the effluent. It was also found out that the ammonium nitrogen was effectively removed in the activated carbon beds by the mechanisms of microbiological assimilation and nitrification. However, in the"C"process, the nitrification process was dominated by the nitrite forming stage, and consequently the nitrite concentration of the effluent from the carbon bed is much higher than that of influent. Meanwhile, the carbon bed of the "C"process exhibited considerably high removal efficiency for nitrate. This is considered to be due to the mechanisms of biological denitrification and reduction of nitrate by a biodegradation product, alcoholic cthyl acid, into N_2 under the oxygen deficient condition in the carbon bed. In the "O_3 + C"process, the nitrification process was carried to the end with formation of nitrate under oxygen-sufficient conditions in the carbon bed. As a result, the nitrate concentration in the effluent increased markedly over the influent. The increased hydrogen ions, H~+ resulted from nitrification can be neutralized by the hydroxide ions, OH~+ dissociated from the carboxide groups on the activated carbon surface, thus preventing the effluent pH from dropping significantly.

本文对粒状活性炭吸附法和臭氧一活性炭吸附法两种处理流程(简称“C”流程和“O_3+C”流程)进行了从饮用水中去除三态氮的对比试验。结果表明,臭氧化能够将有机氮氧化成氨氮;亚硝酸盐氮氧化成硝酸盐氮,从而使它们在出水中的含量增加。试验还发现,在活性炭滤床中通过生物同化和硝化作用等机理有效地除去了氨氮。但是在“C”流程中硝化过程以亚硝化阶段为主,使出水中亚硝酸盐浓度远大于进水浓度。同时,“C”流程具有相当的硝酸盐去除率。
