异养菌对不同极限黏度无磷聚合物稳锌稳磷性能的影响

研究了不同极限黏度无磷聚合物AA/AMPS/HPA在含异养菌循环水中对Zn2＋和PO3-4的稳定性能，结果表明：极限粘度不同AA/AMPS/HPA对Zn2＋和PO3-4的稳定性能差别不大；在Ca2＋1000mg/L、碱度280mg/L条件下，异养菌对AA/AMPS/HPA稳定锌盐性能的影响较小，46d后稳锌率为75％左右；该条件下异养菌对AA/AMPS/HPA稳定磷酸盐性能的影响较大，46d后稳磷率仅为65％左右；当配水碱度增加到900mg/L后AA/AMPS/HPA对Zn2＋和PO3-4的稳定效果均较差，稳锌率和稳磷率分别为45％和40％。

Effects of Heterotrophic Bacteria on Stability of Non -phosphorus Copolymers with Different Limiting Viscosity to Zn2＋ and PO3 -4

This article studies the stabilities of non -phosphorus polymers AA/AMPS/HPA with different limiting viscosity to Zn2＋ and PO3 -4 in high heterotrophic bacteria circulating water .The results show that the stabilities of AA/AMPS/HPA with different limiting viscosity to Zn2＋ and PO3 -4 are almost the same .In the circulating water with Ca2＋ 1000 mg/L and alkalinity 280 mg/L ,the effect of heterotrophic bacteria on the stability of AA/AMPS/HPA to Zn2＋ is little .After 46d the steady rate of Zn2＋ is about 75% .In the circulating water with Ca2＋ 1000mg/L and alkalinity 280 mg/L ,the effect of heterotrophic bacteria on the stability of AA/AM PS/HPA to PO3 -4 is great . After 46d the steady rate of PO3 -4 is about 65% .When the alkalinity is 900mg/L ,the stabilities of AA/AM PS/HPA to Zn2＋ and PO3 -4 are bad ,w hich are respectively about 45% and 40% .
