I. Introduction: Chinese name: polyacrylamide English name: PAM Executive Standard: GB17514-2008 Specification: anionic, cationic, nonionic, amphoteric as flocculants for sewage and organic wastewater treatment such as alcohol wastewater, wastewater, monosodium glutamate factory waste water, sugar water, feed water, textile printing and dyeing wastewater. For urban sewage and meat, poultry and food processing wastewater treatment process and sludge dewatering sludge sedimentation. Polyacrylamide starch factory wastewater treatment plant starch present situation of our country sewage: polyacrylamide is not used before the performance, starch wastage France SNF cationic pam, difficult to recycle, and after discharge will bring environmental pollution. Its water comes mainly from starch washing process - filter press - enrichment and other technology segments. According to the study wastewater contains large amounts of dissolved organic pollutants pam cationic flocculants, such as starch - - protein - carbohydrate -) Carbohydrates - Fat - cationic amino acids and other sludge dewatering pam, followed including N-- P inorganic compounds, and in the technical department learned also contains a certain amount of volatile acids - ash, is a biochemistry better high concentration organic wastewater, but due to the high salt content of ammonia and more intractable. These organic wastewater discharged into water bodies to consume large amounts of oxygen, such as direct discharge without treatment, it will cause serious pollution to the environment. France SNF cationic pam, purifying agent pam (Figure), Ma'anshan cationic pam provided by the Hubei Environmental Protection Engineering Co. Spirit. Environmental Engineering Co., Ltd. Hubei Spirit (hbsshb.com) is a leader in Wuhan, water treatment chemicals, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
