Inhibition to biological treatment process by seven naphthalene derivatives was investigated with Rank Cell respirometer, and all the test chemicals were proved to be potential inhibitors to both activated sludge process and nitrification at different level.

用Rank Cell呼吸仪研究了2-萘酚、1-萘胺、5-氨基-1-萘酚、1-氨基-4-氯萘、2-萘磺酸、2-氨基-1-萘磺酸和7-氨基-4-羟基-2-萘磺酸等七种萘系列有机化合物对生物处理过程的抑制，证明被测化合物对活性污泥过程和硝化过程均有不同程度的抑制作用。

In this study, aerobic biodegradability of 26 different kinds of dyes was tested, using static flask screening test, Warburg respirometer and semi—continuous activated sludge system; then biodegradability of 22 of the dyes under anaerobic condition was investigated by batch and continuous—flow anaerobic digesters; anaerobic metabolic substances of some dyes were analysed by several methods and the pathway of anaerobic degradation of C.

本文用静置烧瓶筛选试验法、瓦勃氏呼吸仪试验法和半连续活性污泥法对26种不同化学结构类型的染料的好氧生物降解性能进行了测定评价；对其中22种染料用间歇厌氧消化反应器和连续流厌氧反应器进行了厌氧生物降解性能的试验，采用多种仪器对部分染料的厌氧降解产物进行检测，对1种蒽醌染料的厌氧降解途径作了推测。

Inhibition to activated sludge process by 2-naphthol was also investigated by Warburg respirometer to verify the conclusion drawn from Rank Cell respirometer test. 2-Naphthol in low concentration was biodegradable, hence resulted in the acceleration of respiration, while in higher concentration 2-naphthol would dramatically inhibit microorganisms respiration on account of high K〓 and electron density.

用Warburg呼吸仪研究了2-萘酚对活性污泥过程的抑制作用，验证了RankCell呼吸仪的研究结论，发现低浓度下2-萘酚自身能被生物降解而使活性污泥中微生物呼吸速率升高；浓度增加后2-萘酚因良好的脂溶性和强亲核能力而对活性污泥过程产生强抑制。

试验发现，按照ERP-SBR方式运行可以大大减小化学除磷池的规模，而且石灰总耗量仅为城市污水后置沉淀系统的4.5%～9%，产生化学污泥含磷率为17%，相当于含73～83%磷酸盐，使化学沉积物具有较明显的回收价值。

The underwater enclosure was built along the boundary of target water body and the lake bottom sludge was filled into the enclosure by twisting-suction dredging ship according to designing elevation for the purpose of formation of slope riffle, which will improve natural condition of littoral zone of lake, and create favorable habitation condition for ecological restoration in littoral zone of lake.

文章介绍最新开发的湖滨陡坎沿岸水域基底修复技术，主要采用人工方法在需要进行大型水生植物群落恢复的湖滨陡坎沿岸的水域实施基底修复工程措施，在目标水域边界构筑水下围埝，采用绞吸式挖泥船将疏浚的湖泥按设计高程要求吹填至基底修复工程区内，形成缓坡浅滩，改善湖泊沿岸带自然条件，为湖泊沿岸带生态修复创造良好的生境条件。

However, if you swim in outdoor natural river, lake and sea, you must pay attention to the followings: water must be clean running water without any infectious disease; river bottom must be sand bottom without any sludge, riprap, growing float grass, submerged rock, sharp plants and fishes injuring human; zone must be one without busy transportation with smooth water flow.

经过卫生防疫部门检查合格的开放游泳池当然是比较理想的游泳场所，但如果在户外天然的江河湖海中游泳则必须注意：水必须是清洁、无传染病的活水；河底必须是无淤泥、乱石、丛生水草、暗礁、尖利植物及伤人的鱼类的沙底；水流平缓而非交通频繁地带。
