摘要
制药废水一直是水处理领域所关注的热点和难点,经过对某医药中间体废水的分析与研究,在实际工程中进行分类、分步治理:含盐废水通过双效蒸发提取盐类物质;难生化的废水强化预处理,提高生化性;综合废水采用物化+生化+高级氧化处理工艺。调试及运行表明,总BOD5和COD的去除率分别达到99.5%和99.8%,出水水质稳定达到GB 8978-1996的Ⅱ级标准,并满足山东省小清河流域水污染物综合排放标准(DB 37/656-2006)表2一般保护区域最高允许排放浓度标准要求。
Pharmaceutical wastewater is one of the refractory wastewater with high concentration. After an analysis of pharmaceutical wastewater, step-by-step treatment was carried out ： Extraction of salts substances from high salinity water by the double-effect evaporation system ; Strengthen pretreatment of hard biodegradable wastewater and improve its biochemical; Transformation-Biochemistry-Advanced Oxidation Process to treat comprehensive wastewater. The results indicated that the removal rate for BOD5 and COD was over 99.5% and 99.8%respectively. The system operates steadily with the treated water quality up to Ⅱ -class criteria specified in the Integrated Wastewater Discharge Standard （GB 8978-- 1996） ,and satisfying Xiaoqing River basin in Shandong Province General water pollutant discharge standard （DB 37 / 656--2006） Table 2 general protection of the regional maximum allowable emission concentration standards.
