摘　　要：目前,我国大多数城市污水处理厂出现了进水COD浓度偏低的现象,致使污水厂运行效果较差。在感潮河地区,由于受不规则半日潮的潮汐规律影响,这一现象尤为严重。分析表明COD浓度偏低的污水进入污水厂处理,不但加重了污水厂的运行负担,而且给节能减排工作带来严重后果。以南方某镇污水厂为例,分析了造成污水处理厂进水COD浓度偏低的主要原因,有针对性地提出了解决措施,以供污水处理厂提高进水浓度作为参考。At present, the phenomenon of low influent COD concentration appears in most of the municipal sewage treatment ptants in China, which causes a poor operation effect. The phenomenon is particularly serious due to the irregular semi-diurnal tidal regime effects in tidal river zone. Once the low influent COD concentration sewage flows into a sewage treatment plant, it not only increases the operation burden of sewage treatment plant, but also brings serious consequences of energy conservation. The main reasons for the low influent COD concentration in a sewage treatment plant in southern China were ana- lyzed, and the targeted solutions were proposed to provide reference for improving influent concentration of sewage treatment plants.
