摘要
景区污水排放量增加且进水NH3-N含量过高,导致出水NH3-N严重超标。改造工程在充分利用原有构筑物的基础上,增加了曝气硝化池、污泥浓缩池和污泥回流系统,改造后出水水质达到《污水综合排放标准》(GB 8978—1996)新改扩一级标准。
The effluent NH3 - N could not meet the discharge standard, because of the discharge quantity increase and high content of NH3 - N in the influent. Based on the former treatment system, aerated nitrification tank, sludge thickening tank, sludge return system were added in reconstruction project. After the reconstruction, the effluent quality meets the first class criteria of Integrated Wastewater Discharge Standard （ GB 8978 - 1996）.
