摘要:
为深度分析预氯胺、预氯化和预臭氧对低浊地表水处理效果的影响，针对江苏X市水源水开展三种预氧化中试，对比了中试各工艺段出水水质主要指标。结果表明，三种预氧化在常规处理和深度处理工艺段对浊度的去除效果均比较明显，其中预氯胺较为突出；预臭氧投加量对UV254去除率影响不大，而预氯胺和预氯化对UV254的去除率均随着投加量的增加而升高，但经深度处理后三种预氧化总体处理效果相当；在预氯化和预臭氧投量分别为2.0和1.5 mg/L时，对CODMn的去除率相对较高。因此，针对低浊水的预氧化工艺选择应根据原水水质、季节变化、水厂处理工艺及运行成本进行综合考虑和动态调整。
Abstract:
A pilot-scale study was conducted using the raw water from X city, Jiangsu Province, to comprehensively evaluate the influence of three pre-oxidation methods, namely pre-chloramination, pre-chlorination, and pre-ozonation, on the treatment efficiency of low-turbidity surface water. The effluent quality parameters across each process stage were systematically monitored and comparatively analyzed. The turbidity removal efficiency of the three pre-oxidation methods was relatively evident in both conventional and advanced treatment processes, with pre-chloramination demonstrating particularly notable performance. The dosage variation of pre-ozonation exerted minimal influence on the UV254 removal efficiency. In contrast, both pre-chloramination and pre-chlorination exhibited increased UV254 removal efficiencies with higher dosages. Nonetheless, following advanced treatment, the overall performance of the three pre-oxidation methods remained comparable. The higher CODMn removal efficiency was achieved when 2.0 mg/L of pre-chlorination and 1.5 mg/L of pre-ozonation were applied, respectively. Therefore, the selection of pre-oxidation processes for low-turbidity water should be comprehensively evaluated and dynamically adjusted according to raw water quality, seasonal variations, treatment processes, and operational costs.
