中國(guó)工程院院士錢易表示，現(xiàn)有成熟技術(shù)能使污水處理標(biāo)準(zhǔn)從一級(jí)A提高到地表水四類，每噸處理成本只需增加1至2毛錢。但當(dāng)前污水處理費(fèi)價(jià)格形成機(jī)制尚未完善，加上一些地方政府承諾的污水處理補(bǔ)貼長(zhǎng)期拖欠難到位，污水處理廠連日常運(yùn)營(yíng)資金都難以維系，加大投入改造工藝技術(shù)的積極性不高。

　　違規(guī)成本低導(dǎo)致偷排現(xiàn)象高發(fā)。湖南株洲、江蘇南通等地多處污水處理廠屢現(xiàn)出水水質(zhì)異常，經(jīng)檢查發(fā)現(xiàn)為上游企業(yè)偷排工業(yè)廢水，導(dǎo)致進(jìn)水遠(yuǎn)超處理能力所致。潘安君說(shuō)，偷排工業(yè)廢水被查明后罰款的上限不過(guò)3萬(wàn)元，有的僅罰款幾千元，現(xiàn)有法規(guī)政策對(duì)違法偷排行為的震懾力遠(yuǎn)遠(yuǎn)不夠。

聚丙烯酰胺---造紙工業(yè)

聚丙烯酰胺在造紙領(lǐng)域廣泛用作助留劑、助濾劑、均度劑等以提高紙張的質(zhì)量。其主要應(yīng)用在兩方面，一是提高填料，顏料等的存留率；二是提高紙張的強(qiáng)度。還可用于造紙生產(chǎn)的廢水處理和纖維回收。

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.

非離子聚丙烯酰胺 Nonionic Polyacrylamide 

產(chǎn)品特性Product Features

該產(chǎn)品是丙烯酰胺單體的均聚物，經(jīng)造粒、干燥、粉碎而成，離子化程度低。產(chǎn)品外觀呈白色顆?；蚍勰┕腆w狀。絮凝性能受水pH值和鹽類波動(dòng)的影響小。在酸性條件下優(yōu)于陰離子型，絮凝強(qiáng)度比陰離子型高分子絮凝劑的強(qiáng)。

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.
