对聚硅酸锌絮凝剂(PZSS)中硅锌物质的量比、投加量、水样pH值、絮凝慢搅时间及搅拌强度、沉降时间等因素对其絮凝性能、处理后清液和滤液残锌量的影响进行了研究,同时通过光子相关光谱法(PCS)、紫外吸收(UVA)扫描法对其粒径分布、Zn2+和Zn2+水解聚合物与聚硅酸的作用进行了进一步证明。结果表明,硅锌比1∶1、投加量1 mL/L、水样pH 7.0、慢搅时间10 min,沉降10 min的条件下,即可得到浊度和溶液中残锌量符合国家生活饮用水卫生标准的处理液。
The results showed that the flocculation performance, the concentration of silicon and zinc in polysilicate zinc flocculant (PZSS), the dosage, the pH value of water sample, the time of flocculation, the stirring intensity, the settling time, The effect of Zn2 +, Zn2 +, Zn2 + and polysilicic acid was further studied by means of photon correlation spectroscopy (PCS) and ultraviolet absorption (UVA) scanning. The results showed that turbidity and residual zinc content in the solution were in line with national life when the ratio of silicon to zinc was 1: 1, the dosage of 1 mL / L, the pH of water sample 7.0, the time of slow stirring 10 min, and the sedimentation time 10 min. Drinking water sanitation standard solution.
