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%。%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% .
