摘要:
针对东北高寒地区某浅水型水库在夏秋季发生蓝藻水华后，以其为水源的D水厂现有工艺无法满负荷运行、处理难度大的问题，分析了原水蓝藻特性及已有处理工艺现状，并采用一体化水平管沉淀分离中试设备进行试验，探求在该水质条件下对相关水质指标的去除效能。结果表明，当聚硅氯化铝(PASC)投加量为3 mg/L、处理水量为8 m3/h、水平管沉淀池的过流负荷为20.05 m3/（m2·h）时，中试设备对浊度的去除率为98%、对CODMn的去除率为49%、对UV254的去除率为89%、对藻密度的去除率为95%；同时该中试装置的特殊结构和材质可有效避免藻类的附着及生长，对水厂安全平稳度过蓝藻水华期具有重要借鉴意义。
Abstract:
When cyanobacteria bloom occurs in a shallow reservoir in the alpine region of Northeast China in summer and autumn, the existing process of D water treatment plant with the reservoir as water source could not operate at full capacity and the treatment effect was difficult to be guaranteed. Characteristics of cyanobacteria in raw water and operating status of the existing treatment process were analyzed. A pilot integrated horizontal tube sedimentation separation plant was applied to investigate the removal efficiency of related water quality indexes under the condition of cyanobacteria bloom. When dosage of poly-aluminum silicate chloride (PASC) was 3 mg/L, water treatment capacity was 8 m3/h and hydraulic loading was 20.05 m3/(m2·h), removal efficiencies of turbidity, CODMn, UV254 and algae density by the pilot plant were 98%, 49%, 89% and 95%, respectively. Moreover, the unique structure and material of the pilot plant could effectively avoid the attachment and growth of algae, which has important reference significance for the water treatment plant to safely and smoothly pass the cyanobacteria bloom period.
