The processes of the wastewater treatment plant (WWTP) open up options to influence the composition of the effluent. These options will be used to design the effluents composition such that the conditions for ecotechnology in the receiving waters are supported. The basis for this investigation is to identify the decisive control parameters in the receiving water (project P2). The process water treatment will be a central object of investigation. Due to high ammonia concentration of the process water, high sludge concentration and high temperature, it can be a source for accumulation of compounds and micro-organisms. The idea is to dose either compounds or micro-organisms from the sludge process water reactor to the effluent of the WWTP, depending on the requirements from river water quality and resilience. The investigations will focus on the options of (i) nitrate dosing after nitrification of sludge process water, (ii) nitrifyers dosing, since nitrifyers are highly concentrated in a sludge process water unit, and (iii) accumulating specific micro-organisms able to degrade polluting organics, to be dosed on demand. Last, temperature patterns of effluent and river will be analysed with regard to the potential of heat exchangers in the effluent.

污水处理厂（WWTP）的工艺为影响污水成分提供了多种选择。这些备选方案将用于设计污水成分，以便支持接收沃茨的生态技术条件。本次调查的基础是确定受纳水体中的决定性控制参数（项目P2）。 工艺水处理将是调查的中心对象。由于工艺用水的高氨浓度、高污泥浓度和高温，它可能是化合物和微生物积累的来源。这个想法是根据河流水质和恢复力的要求，将污泥处理水反应器中的化合物或微生物加入到污水处理厂的出水中。调查将集中在以下选项：（i）污泥工艺水硝化后的硝酸盐投加;（ii）硝化剂投加，因为硝化剂高度集中在污泥工艺水单元中;以及（iii）积累能够降解污染有机物的特定微生物，按需投加。最后，将分析污水和河流的温度模式，以及污水中热交换器的潜力。
