Based on the success of that project prompted the government carried out a similar project in the sam ka tsuen typhoon shelter in 2004 鉴于该项工程成效理想，政府决定于2004年在三家村避风塘实施同类的生化处理。
Abstract : a potential immobilized microorganisms supporter - chitin is reported , and it has been used in the wastewater biochemical treatment 文摘:介绍了一种极具潜力的微生物固定化载体? ?甲壳素，并应用于豆制品厂及精细化工厂废水的生化处理。
Thus , oxidation pretreatment technology is needed to transform these substances into smaller molecules that can then be readily degraded biochemically 因此，有必要通过氧化方法对难生化降解的农药废水进行预处理，使废水中的难生化降解物质转化为易于生化处理的小分子化合物。
With the increase in pesticide wastewater of compounds that are difficult to biodegrade , conventional biochemical treatment methods cannot completely remove contaminants from wastewater 摘要随着农药废水中难生物降解化合物的增加，常规的生化处理方法无法完全去除水中的污染物。
Dyeing and printing wastewater was treated biologically and then by " fluidized activated carbon " in place of flocculation to lower the treatment cost , decrease the sludge quantity and raise the treatment to a very high level 摘要印染废水经过生化处理后，采用“流炭法”取代混凝沉淀，可节省处理费用，减少污泥生产量，同时可使废水达到很高的处理要求。
This was a particularly severe problem in the lower shing mun river in sha tin , but dredging and a bio - remediation project undertaken in 1997 made a huge difference to the smell of the river 沙田城门河下游以往曾有河水发出恶臭的问题。政府于1997年治理河道，在河床口进行挖掘污染沉积物工程及利用生化处理方法改善沉积物质素，难闻气味已较以前大幅度减少。
Sauce wastewater is characterized with great change in quantity and quality , complicated composition and high level in organic content and coloring this kind of industry wastewater is difficult to treat according to the of aerobic biological treatment 摘要酱油废水有机物浓度和色度都非常高，成分复杂，水质不稳定，生化处理工艺污泥产量高，是难处理的工业废水，采用单一好氧生物处理工艺很难达标。
The results show that the chitin has an excellent adsorption with microorganisms and that the microorganisms on the chitin are more effective in wastewater biochemical treatment compared with those on the activate carbon under the same condition 研究表明：甲壳素对微生物有着良好的吸附性能，保持它们高的生物活性，与活性炭为载体的微生物固定化方法在废水生化处理中的应用效果相比较，甲壳素固定化法有着更好的处理效果。
Bio - remediation can be achieved in different ways , but in the case of the shing mun river , it involved injecting calcium nitrate into the sediment , thus converting anoxic pollutants into odourless gases such as nitrogen or carbon dioxide , and in the process removing offensive odours 生化处理可以多种形式进行，以城门河为例，处理程序是将硝酸钙注入沉积物内，使缺氧的污染物转化为氮或二氧化碳等无臭气体，从而消减臭味。
Abstract : the less - biodegradable printing and dyeing wastewater has been pretreated by an iron chipping - filtration process . the results indicate that the pretreatment process can improve biodegradability of the wastewater and reduce cod and colority , resulting in the benefit to the follow - up biological treatment 文摘:采用铁屑过滤法预处理可生化性差的印染废水，能改善废水的可生化性，降低废水的cod和色度，有利于后续生化处理。
