The removal rates of Phenol were 85％, 90％, the removal rates of TOC reached 80％, 86％ respectively when the phenol wastewater at 350mg/L was treated for 35 hours. The weight of biofilm formation on MPPE was 64％ and 34％ higher than that on PPE at this two wastewaters.

质量浓度为120mg/L的含苯酚废水在好氧生物填料柱中处理14 h后，PPE和MPPE对苯酚去除率分别为82％和93％，TOC去除率分别为78％和89％；质量浓度为350mg/L的含苯酚废水处理35h后苯酚去除率分别为85％和90％，TOC去除率分别为80％和86％；两种不同质量浓度的含苯酚废水降解后MPPE上微生物挂膜量分别比PPE提高约64％和34％。

In a traditional total quantity distillation setup or a half micro-distillation setup, the separation and absorption of ammonia and constant volume must be done separately, so the analyzing program is complex and needs long analysis time. By the rapid azotometer (Type: NC2), the ammonia in the waste water could be analyzed through one step which includes separation, absorption and titration. Compared with the tradition analysis methods, the ammonia-N in waste water can be analyzed more quickly.

含氨废水通过NC2定氮装置将氨分离，吸收，滴定集为一体，克服了传统全量蒸馏装置或半微量蒸馏装置将废水中的氨分离，吸收，定容分步进行的复杂，耗时缺点，从而达到快速测定废水中氨氮含量的目的。

Organic and compound cation garrulous coagulates the agent is to use chemical law compound a kind of new-style cation garrulous coagulates agent, belong to domestic and international initiate, with other and groovy drug photograph comparing has 5 big advantages: The photograph such as aluminium of as aggregate as commonly used drug chloridize, aggregate and vitriolic iron, vitriolic aluminium is compared, coagulate with garrulous of polypropylene acyl amine the agent is used jointly, medical dose is little, reduce useless water treatment to expend about 20 ％ thereby, 30 ％; Effect of processing liquid waste is good, garrulous is round settling speed is fast, make liquid waste can second birth is used, managing water natural resources; Its garrulous group is sedimentary filterability can be good, slime can reclaim inside entire plant, namely energy-saving be helpful for protecting an environment again; Corrode to equipment small; Have muti_function, have agglomeration effect already, again garrulous coagulates action and the action that aid filter, can serve as filter aid.内容来自www.ch-water.com

有机复合阳离子絮凝(使液体中悬浮微粒集聚变大或形成絮团，从而加快粒子聚沉，达到固-液分离的过程)剂是利用化学法合成的一种新型阳离子絮凝(使液体中悬浮微粒集聚变大或形成絮团，从而加快粒子聚沉，达到固-液分离的过程)剂，属国内外首创，与其他常规药剂相比具有五大优点：与常用药剂聚合氯化铝、聚合硫酸铁、硫酸铝等相比，与聚丙烯酰胺类絮凝(使液体中悬浮微粒集聚变大或形成絮团，从而加快粒子聚沉，达到固-液分离的过程)剂联合使用，药剂量少，从而降低废水处理(通过物化方法去除水中一些物质的过程)费约20％—30％；处理废水效果好，絮团沉降速度快，使废水能再生利用，节约水资源；其絮团沉渣过滤性能好，煤泥可全部厂内回收，即节能又有利于保护环境；对设备腐蚀小；具有多功能，既有凝聚作用，又有絮凝(使液体中悬浮微粒集聚变大或形成絮团，从而加快粒子聚沉，达到固-液分离的过程)作用和助滤作用，可作为助滤剂。
