1、专业资料摘要随着国家对环保问题的重视，水污染问题正被提出研究，目前水处理主要对象是高浓度有机废水和富营养化废水。而对含盐废水的处理研究还相对较少，本设计根据当地的情况结合自身所学的情况来设计，针对榨菜行业高盐、高COD、高BOD废水治理难度较大，工程量较大等特点，进行方案设计。榨菜生产废水COD高达3000mg/L，盐度、有机物浓度及氮、磷浓度均很高，直接排放严重影响了当地水体水质和生态环境，对当地民众的身体健康和生活带来不良影响。需对榨菜生产过程中产生的废水进行治理达标后排放。过程包括对处理设备的计算，最终达到国家的一级排放标准。尤其是含盐量要降到灌溉用水标准，因为这个问题正是困扰榨菜
2、厂发展的瓶颈问题。设计污水处理能力为10m3，属于小型污水处理厂。本设计采用A/O好氧厌氧法处理市污水，其特点是工艺流程简单，构筑物少；处理效果稳定，出水水质好；污泥产生量少，污泥的性质稳定。设计中对污水处理工艺和污泥处理方案进行了选择论证；对污水、污泥处理构筑物进行了工艺设计计算；对废水处理厂进行了平面、高程布置，并绘制了平面布置图、高程图。关键词含盐废水；两段式生物处理工艺；污水处理word完美格式专业资料AbstractWiththenation'sattentiononenvironmentalissues,waterissuesarebeingputonthemaintarge
