摘 要:本篇设计阐述了生产啤酒的各阶段废水以及其他污染物的产生源头,然后考虑了用厌氧生物处理和好氧生物处理联合起来的工艺设计,最终选取了UASB-CASS的联合工艺来对啤酒废水进行处理。此工艺可将BOD5从650~790mg/L降低至40mg/L,COD从1400~1700mg/L降到90mg/L以下,SS从550mg/L降至70mg/L以下,使最后排出的水遵守国家相关部门排水标准。33784 毕业论文关键词:啤酒生产废水;UASB反应器;CASS反应器;污泥浓缩池
5000m3/d Beer Wastewater Treatment Process Design
Abstract:This design describes the beer production of each stage of the wastewater and other pollutants origin,and then consider the aerobic biological treatment process design of combined with anaerobic biological treatment,and ultimately selected the UASB-CASS process to the brewery wastewater processing.This process can be BOD5 from 650 to 790mg/L reduced to 40mg/L,COD from 1400 to 1700mg/L drop to less than 90mg/L,SS from 550mg/L fell to below 70mg/L,the outlet water to comply with the relevant departments of the state standard of drainage.
