Gongye shui chuli, 2023 某城镇污水处理厂来水主要是工业企业处理后尾水，废水B/C在0.1左右，可生化性差，易造成氧化沟内污泥生长不佳、污泥浓度低，导致出水不能达标排放。针对该污水处理厂现存问题通过中试研究提出了添加碳源与运行调控相结合的技术方案。结果显示，以乙酸钠为补充碳源对氧化沟内的污泥增长、污水处理厂的出水水质以及运行成本等最为有利。经现场调控，确定污水处理厂最终技改方案：1）乙酸钠投加量为135 mg/L，投加位置为污水处理厂缺氧池进水口处；2）在缺氧池前1/3段底部敷设穿孔管，通过曝气使缺氧池内污泥的氧化还原电位 ...

Gongye shui chuli, 2015 以某机床厂污水处理工程为实例,介绍机床厂各类生产污水预处理及综合污水处理的工艺、工艺参数及效果。针对机床厂生产污水复杂的来源及成分,首先运用破乳、混凝、中和、气浮等方法对各类生产污水进行预处理,再利用水解酸化、生物接触氧化工艺完成对综合污水的处理。生产污水出水水质符合DB21/1627—2008《辽宁省污水综合排放标准》,综合污水出水可以进行厂内中水回用。该工艺利用自控系统,易于管理,处理效果稳定,实现了污水无害化处理。
