我国沿海城市海洋渔业资源丰富，近年来水产加工市场不断扩大，相应的水产品加工的规模也在不断扩大，水产品加工产生废水的排放量越来越大，而环保部门要求一定规模的水产品加工企业都必须建立专门的废水处理站。由于水厂品加工废水具有有机物含量比较高，可生化性比较好的特点，选用生物处理方法进行处理。
针对烟台市鳕鱼加工废水的特点，本设计主要介绍用水解酸化+气浮+曝气生物滤池处理工艺。本设计从计算，运行，技术，经济分析，从而表明水解酸化+气浮+曝气生物滤池对乳品废水处理的可行性。本设计中乳品废水的处理主要构筑物组成为：调节池、水解酸化池、气浮池。曝气生物滤池，污泥均化池等。利用水解酸化+气浮+曝气生物滤池工艺处理乳品废水的特点是占地面积小、运行费用低、出水稳定。其设计出水可达到《国家污水排放综合标准》（GB8978—1996）中的二级标准。

China's coastal city of rich marine fishery resources, aquatic products processing market in recent years constantly expanding, the corresponding size of aquatic products processing is also growing, and aquatic produce processing wastewater emissions increasing, and environmental protection departments require a certain amount of aquatic product processing Enterprises must be the establishment of specialized waste water treatment station. As water plant for processing waste water with high content of organic matter, chemical and biological characteristics of a better choice biological treatment method for p
