再生水甲醇投加成本运算

再生水资源是水资源的一种特殊形式，它的价格是影响污水回用的重要因素之一。再生水价格有多种形式，其中甲醇的投加是一笔不小的成本。以污水处理厂二级出水为水源进行深度处理以实现污水资源化的过程中，存在着总氮含量高、有机物含量低的水质特点。再生水处理中反硝化阶段需要有机物，也就是碳源。碳源影响脱氮效果，投加甲醇为外碳源可以促进反硝化水平。

Reclaimed Water Methanol Additive Cost Computation

Renewable water is a special form of water resources, its price is one of the important factors influencing the wastewater recycling. Reclaimed water price there are a variety of forms, including methanol additive is a not small cost. With secondary sewage treatment plant as the water depth processing in order to realize the wastewater reuse in the process, there is a high total nitrogen content, low organic matter content of the water quality characteristics. Regeneration of denitrification stage need to organic matter in water treatment, namely carbon source. Carbon source influence denitrification effect, adding the methanol as external carbon source can promote the level of denitriflcation.
