中国工程院院士钱易表示，现有成熟技术能使污水处理标准从一级A提高到地表水四类，每吨处理成本只需增加1至2毛钱。但当前污水处理费价格形成机制尚未完善，加上一些地方政府承诺的污水处理补贴长期拖欠难到位，污水处理厂连日常运营资金都难以维系，加大投入改造工艺技术的积极性不高。

　　违规成本低导致偷排现象高发。湖南株洲、江苏南通等地多处污水处理厂屡现出水水质异常，经检查发现为上游企业偷排工业废水，导致进水远超处理能力所致。潘安君说，偷排工业废水被查明后罚款的上限不过3万元，有的仅罚款几千元，现有法规政策对违法偷排行为的震慑力远远不够。

聚丙烯酰胺---造纸工业

聚丙烯酰胺在造纸领域广泛用作助留剂、助滤剂、均度剂等以提高纸张的质量。其主要应用在两方面，一是提高填料，颜料等的存留率；二是提高纸张的强度。还可用于造纸生产的废水处理和纤维回收。

PAM is widely used as retention agent, filter aid, regularity of agent in the field of papermaking in order to improve the quality of paper. It is mainly used in two ways, one is to improve the packing, pigments and other retention; the second is to improve the strength of paper. It can also be used for paper production wastewater treatment and fiber recycling.

非离子聚丙烯酰胺 Nonionic Polyacrylamide 

产品特性Product Features

该产品是丙烯酰胺单体的均聚物，经造粒、干燥、粉碎而成，离子化程度低。产品外观呈白色颗粒或粉末固体状。絮凝性能受水pH值和盐类波动的影响小。在酸性条件下优于阴离子型，絮凝强度比阴离子型高分子絮凝剂的强。

The product is the polymer of acryl amide monomer which formed after granulation, drying and crushing , with low degree of ionization. The product appears white solid particles or powder. Flocculation performance is affected little by the fluctuation of the water pH and salt. It is better than anionic under acid condition and flocculation strength is better than anionic polymer flocculants.
