城市生活污水厂处理工业废水的运营管理对策
- Title:
- Suggestions on Operation and Management of Urban Domestic Sewage Treatment Plant Handled Industrial Wastewater
- 摘要:
- 以重庆市G污水处理厂为例，探讨接纳工业废水的生活污水处理厂运营管理对策。通过对比G污水处理厂进、出水水质与设计值，调查入网接管企业废水排放情况，分析污水处理厂运行情况，发现造成污水处理厂水质不稳定的主要原因是进水C/N/P比例失衡、可利用碳源少、缺少适宜工业废水的处理工艺、调控运行不当以及入网企业超允许浓度排放等。完善污水处理工艺，加强精细化控制，规范企业接管许可，实施多部门监管联动，提升风险防范和应急处置能力是改善此类污水处理厂出水不稳定的重要措施。
- Abstract:
- Taking G sewage treatment plant in Chongqing as an example, we discussed the operation and management countermeasures for a sewage treatment plant which treated industrial wastewater. We analyzed the influent and effluent quality and the operation of G sewage treatment plant, and investigated the industrial wastewater discharge. It was found that the main reasons for the instability of the water quality of the sewage treatment plant were unbalanced C/N/P ratio of influent, shortage of available carbon sources, lack of industrial wastewater treatment process, unreasonable regulation, and excessive allowable concentration discharge from enterprises. Important measures, such as perfecting sewage treatment process, strengthening detail control, standardizing corporate drainage pipeline connection license, implementing multi-department supervision linkage, improving the ability of risk prevention and emergency response were put forward to improve the instability of effluent from the similar sewage treatment plants.
