混凝、絮凝和滤池反冲洗产生的污泥负荷废水 在排放或回收方面给许多水供应商带来了很大的问题 可能性。德国德累斯顿的水厂霍斯特维茨（Hosterwitz）对此进行了调查 在选择生物处理之前，污泥循环利用的各种选项，以及 复垦。此外，还有不同的待遇 研究了各种技术，以评估由此产生的污泥优势 戒断和治疗。所考虑技术的可行变体（间接 现有技术的排放、修改和补充，紧凑型 凝固和膜过滤）的设计允许 性能、空间需求和由此产生的资本支出（资本支出）的比较 以及运营费用（OPEX）。经过调查和经济比较， 通过外部设备直接从混凝/沉淀池中提取污泥的选项 选择了一个污泥储存库作为水池或储罐。从沉淀池中提取污泥是最具经济效益的解决方案，但该方案的低成本面临技术挑战 缺点，因为水和污泥处理不能完全分离 因此，不能排除相互作用。提供额外的污泥储存 体积和处理似乎在技术上更有利，但占用空间。 一般来说，对现有技术的修改和补充似乎是可行的 从经济角度来看，这是最好的解决方案。最好在现场储存和处理污泥， 如果所需空间可用。如果没有，则采用紧密凝固和膜过滤 是减少污泥产量的更有希望的替代方案。包括5个参考文献、图表。

The sludge burden wastewater from coagulation, flocculation and filter backwashing may create large problems for many water suppliers concerning discharge or recycling possibilities. The approach taken by the Waterworks Hosterwitz in Dresden, Germany, investigated various options for sludge recycling before selecting biological treatment and subsequent recycling in recultivation. Further, different treatment technologies have been studied to evaluate the resulting advantages concerning sludge withdrawal and treatment. Feasible variants of the considered technologies (indirect discharge, modification and supplementation of the present technology, compact coagulation, and membrane filtration) have been designed to allow for a comparison of performance, space requirements and resulting capital expenses (CAPEX) and operating expenses (OPEX). Following investigation and economical comparisons, the option of direct sludge withdrawal from coagulation/sedimentation basins by an external company, and construction of a sludge storage volume as basin or tank was selected. Sludge withdrawal from sedimentation basins presented the most economically beneficial solution, but the low costs of this option faces technological shortcomings, since water and sludge treatment cannot be completely separated, and therefore, mutual interactions can not be excluded. Providing additional sludge storage volume and treatment appears to be technologically more beneficial but is space consuming. Generally, modification and supplementation of the present technologies appeared to be economically the best solution. Onsite sludge storage and treatment would be preferable, if the required space is available. If not, compact coagulation and membrane filtration are the more promising alternatives to reducing sludge production. Includes 5 references, figures.
