A²O工艺活性污泥黏性膨胀原因及控制措施

Gongye shui chuli
污泥黏性膨胀问题一直是A2O工艺运行控制的难点。郑州市某污水处理厂在运行过程中出现污泥黏性膨胀问题，造成污泥沉降性能变差，SVI逐渐提升至240 mL/g左右，二沉池泥位持续升高。从进水水质、水温、曝气量、浮渣等多方面综合分析引起污泥膨胀的原因，及时从剩余污泥排放量、污泥龄、溶解氧、回流比、水力停留时间等工艺参数调整运行工艺，使污泥膨胀问题得到一定程度的缓解。为彻底消除生物池浮泥，又通过在二沉池配水井精准投加40 mg/L的阳离子高分子絮凝剂，经过一段时间的药剂助沉，明显提高了污泥沉降性能 ...

絮凝调理强化疏浚淤泥脱水固结的工程应用研究进展

Gongye shui chuli
疏浚淤泥的处理处置与资源化利用是当前清淤疏浚工程亟需解决的重要问题，而实现淤泥的有效脱水固结则是解决该问题的必要前提。基于絮凝调理强化疏浚淤泥脱水固结效果的技术路线，已经走在了疏浚工程应用的前沿。针对疏浚淤泥脱水减量这一关键技术，首先梳理并辨析了底泥、疏浚淤泥、污泥等在疏浚领域易混淆的概念以及含水率、含水量等关键参数的本质差异。其次，结合真空预压、土工管袋和机械压滤3种典型脱水工法，系统分析了其在工程应用层面的技术现状及主要瓶颈，并就如何利用絮凝调理技术提升不同工法的脱水效率进行了归纳总结。最后 ...
