Abstract

Abstract Wastewater treatment in semi-natural systems, such as a hydroponic lagoon operating as the third stage of treatment, is becoming more and more popular because of the efficiency of organic matter and nutrient removal. The article presents an analysis of the efficiency of pollutant removal at the mechanical-biological wastewater treatment plant in Gronów with a capacity of Qd = 1125m3/day and a load of 9375 PE. The wastewater treatment plant operates on the basis of activated sludge and biomass settling technology on submerged flow beds. The treatment plant is characterized by a very high variability of wastewater inflow during the year due to periodic inflow of wastewater from tourist resorts in Łagów. The average efficiency of removing pollutants from wastewater was: BOD5 - 98.5%, COD - 92.8%, total suspended solids - 93.2%, total nitrogen - 86.1% and total phosphorus - 69.5%. The study showed that the use of a hydroponic lagoon in the technological system improved the efficiency of wastewater treatment by 1.7% for BOD5, 0.9% - COD, total suspended solids by 4.3%, 6.4% for total nitrogen and total phosphorus- 3.3%.

污水处理厂水培泻湖对污染物的去除效果

半自然系统的废水处理，如水培泻湖作为第三阶段的处理，由于有机物和营养物质的去除效率越来越高，越来越受到人们的欢迎。本文分析了Gronów处理能力为1125m3/d、负荷为9375 PE的机械-生物污水处理厂的污染物去除效率。该污水处理厂以活性污泥和生物质沉降技术为基础，在淹没式流化床上运行。由于Łagów旅游胜地的废水定期流入，该处理厂的特点是一年中废水流入的变异性非常高。平均去除率为:BOD5 - 98.5%， COD - 92.8%，总悬浮物- 93.2%，总氮- 86.1%，总磷- 69.5%。研究表明，在工艺系统中采用水培泻湖，BOD5处理效率提高1.7%，COD处理效率提高0.9%，总悬浮物处理效率提高4.3%，总氮处理效率提高6.4%，总磷处理效率提高3.3%。
