Abstract

This paper present the experiences gained from the study of ten up flow anaerobic sludge blanket (UASB) based sewage treatment plants (STPs) of different cities of India. Presently 37 UASB based STPs were under operation and about 06 UASB based STPs are under construction and commissioning phase at different towns. The nature of sewage significantly varied at each STP. Two STP were receiving sewage with high sulfate and heavy metals due to the mixing of industrial waste. The treatment performance of all UASB reactors in terms of BOD, COD and TSS were observed between 55 to 70% respectively. The post treatment units down flow hanging sponge (DHS) and Aeration followed by activated sludge process (ASP) at two STPs were performing well and enable to achieve the required disposal standards. Results indicate the effluent quality in terms of BOD and SS were less than 30 and 50 mg/L and well below the discharging standards.

摘要

本文介绍了从研究印度不同城市的十个上流式厌氧污泥床（UASB）污水处理厂（STP）中获得的经验。目前，有 37 个基于 UASB 的 STP 正在运行，约有 06 个基于 UASB 的 STP 正在不同城镇进行建设和调试阶段。每个 STP 的污水性质差异很大。由于工业废物的混合，有两个 STP 接收含有高硫酸盐和重金属的污水。所有 UASB 反应器在 BOD、COD 和 TSS 方面的处理性能分别在 55%到 70%之间。在两个 STP 中，采用下流式悬挂海绵（DHS）和曝气后活性污泥法（ASP）的后续处理单元运行良好，能够达到所需的处理标准。结果表明，BOD 和 SS 的出水质量分别小于 30 和 50mg/L，远低于排放标准。
