- 摘要:
- 汕头市某混合废水处理厂设计规模为6×104 m3/d，进水为印染废水和生活污水（比例7∶3），出水执行《城镇污水处理厂污染物排放标准》（GB 18918—2002）一级A标准和广东省《水污染物排放限值》（DB44/26—2001）中城镇二级污水处理厂第二时段一级标准的较严值。因辖区内印染工业废水处理厂的建设，该混合废水处理厂升级改造为生活污水处理厂，出水执行原标准与《练江流域水污染物排放标准》（DB44/2051—2017）的更严值。通过分割原水解酸化池为厌氧池或缺氧池进行生化系统改造，并增加内回流功能，将原水解酸化池+A/O工艺改造为A/A/O微曝氧化沟工艺；通过管线迁改及配套设备更换进行深度处理改造，利旧原高效沉淀池+回转精密滤池工艺。改造完成后，COD、BOD5、SS、NH3-N、TN与TP去除率分别提高约6%、1%、5%、3%、30%和8%，出水指标均稳定优于设计出水标准。工程在不增加污水处理设施的情况下对污水处理厂进行原位提标改造，可为类似项目提供参考。

The effluent quality must meet the stricter values of the first level A limit specified in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002) and the first level limit during the second phase of urban secondary wastewater treatment plants specified in Discharge Limits of Water Pollutants (DB44/26-2001) of Guangdong Province.

2015年广东省环境保护厅印发的《练江流域水
环境综合整治方案（2014—2020年）》提出综合整治
流域水环境，集聚工业产业，建设环保基础设施，对
流域内工业废水治理及城镇污水处理厂排放限值
分别提出新的要求。由于治理效果欠佳，广东省环
境保护厅于2017年8月30日发布《练江流域水污染
物排放标准》（DB44/2051—2017），要求流域范围内
城镇污水处理厂出水自2020年12月31日起执行此
标准。汕头市某混合废水处理厂原进水为印染废
水和生活污水（比例7∶3），出水执行《城镇污水处理
厂污染物排放标准》（GB 18918—2002）一级 A 标准
和广东省《水污染物排放限值》（DB44/26—2001）中
城镇二级污水处理厂第二时段一级标准的较严值，
为响应地区水污染防治政策，势必对其进行提标
改造。

水质提升为一级 A 的升级改造和二期工程的扩建。
一期改造后主体工艺为“水解酸化池+中沉池+A/O
池+斜管沉淀池+回转精密滤池”，二期扩建工程主
体工艺采用“初沉池+水解酸化池+A/O氧化沟+高效

1. 2 运行现状及存在问题
因2019年产业集聚计划的实施，辖区范围内所
有印染企业均迁移至当地印染园，工业废水统一由
园区新建的工业污水处理厂处理，该污水处理厂进
水由以印染废水为主的混合废水转变为生活污水，
故现状实际进水水质与原设计水质差异较大。
改造前，该污水处理厂 2020年 1月—10月平均
进水量为 4. 15×10

对比表1可知，现状实际进水除SS、TN和TP浓度在
设计值范围内，COD 和 BOD

NH

-N 浓度超出设计值。现状实际出水指标均优
于原设计出水标准，并已达到 DB44/2051—2017 要
求，但参考近几年污水处理厂的运行数据发现，出
水TP偶有超标。
