污水

Copolymerization of acrylamidewith(2methacryloyloxyethyl)trimethyl ammonium chlorideinitiated by plasma in aqueous solution was studied.

季铵盐型阳离子聚电解质在污水处理、造纸、采油等许多领域的应用越来越得到人们的认同。

Some water samples from intakes and outlets of 3 wetland pond beds growing Phragmites communis Trin, Typha angustifolia and Cyperus alternifolius were respectively taken for monitoring and contrasting 5 main water quality indexes including dissolved oxygen, chemical oxygen demand, biochemical oxygen demand in 5 days (BOD5), total nitrogen, and total phosphorus month by month all year around, so as to discover influences of different plant species on water purification efficiency.

摘 要：通过对成都活水公园人工湿地中的3种优势挺水植物所在塘床进出水口的5个主要水质指标：水中溶解氧（dissolved oxygen， DO）、化学需氧量（chemical oxygen demand， CODcr）、5日生化耗氧量（biochemical oxygen demand in 5 days， BOD5）、总氮（total nitrogen， TN）、总磷（total phosphorus， TP）的全年逐月对比监测，探索不同植物种类对污水净化效率的影响，并对湿地中不同植物塘净化效率产生差异的原因作了较全面的分析讨论。

Finally, by combining the transmission function for the Tubificidae system with FCASM3 (Fully coupled activated sludge model 3), a sub-microscopic mechanism model for the interaction of Tubificidae and microorganisms was established.

以全耦合活性污泥模型（FCASM3）为基础平台，结合水蚯蚓作用的传递函数，最终建立了污水厂&水蚯蚓-微生物共生系统&细观机理模型。

It was found that dilution ratio larger than 5: 1 was unadequate for measuring OUR variation because the sewage concentration was too low to obtain the accurate value of OUR.

由不同污泥之稀释比测试结果发现，当稀释比达5：1时OUR值已明显受到影响，因污水浓度过低不易测得准确OUR值。

The wandering solitary sage, uncomplacent, unshaken by praise or blame. Unstartled, like a lion at sounds. Unsnared, like the wind in a net. Unsmeared, like a lotus in water. Leader of others, by others unled: The enlightened call him a sage.

独来独往，勤勉努力，任凭褒贬，就象狮子不怕声响，风儿不怕罗网，莲花不怕污水，他指引别人，而不受别人指引，智者们称这样的人为牟尼。

Public sewers are being provided for 38 rural villages and areas that were previously unsewered.

当局正为未有污水设施的38条郊区乡村和地区，提供公共污水渠。

The official sewerage system does not cater to about 45% of Delhi's population, so their waste is illegal, untrapped and hence flows through various drains.

官方污水处理系统，并不能满足百分之45的德里居民，他们的废弃物是没有被阻止、是非法的，之后再流到不同的排水管里，22个排往亚穆纳河的排水管都没有被检验过。

The fresh dewater digested sludge of municipal wastewater treatment plant was suited for vaccinal sludge at the startup of anaerobic reactor and the concentration should not be less 10mg/L; the COD of feed wastewater should be lower than 5000mg/L, and VOL was 20 percent of total VOL; the alkalinity of effluent should be more than 3000mg/L; on the condition of the COD removed 80% can the VOL be elevated.

反应器启动时接种污泥可以选用城市污水处理厂新鲜的脱水消化污泥，浓度不低于10mg/L；进水有机物浓度不高于5000mg/L，容积负荷为满负荷的20％；出水碱度要高于3000mg/L，温度稳定；在有机物的降解率达到80％后再提高负荷。

1 M,with dominant helophyte of Zantedeschia aethiopica ,one kind of fancy and economical helophyte,for low concentration agricultural wastewater treatment is reported here.

报道了以观赏性和经济性植物马蹄莲为主要植物的人工湿地中试床(5 m×1 m×1.1 m)处理低浓度农村污水的研究。

Constructed wetland pilot system (5 m×1 m×1.1 m), with dominant helophyte of Zantedeschia aethiopica, one kind of fancy and economical helophyte, for low concentration agricultural wastewater treatment is reported here.

报道了以观赏性和经济性植物马蹄莲为主要植物的人工湿地中试床(5m×1m×1.1m)处理低浓度农村污水的研究。

Plunder melds and run with this jewel!

掠夺melds和运行与此宝石！

My dream is to be a crazy growing tree and extend at the edge between the city and the forest.

此刻，也许正是在通往天国的路上，我体验着这白色的晕旋。
