屠宰场废水含有各种和大量的有机物质（例如，蛋白质、血液、脂肪和猪油）。为了产生适合于流排放的流出物，化学凝聚和电凝聚技术已经特别地在实验室中试规模上被探索用于从屠宰场流出物去除有机化合物。研究了化学混凝-电絮凝组合工艺处理屠宰废水的可行性，以达到废水达标排放的要求。考察了混凝剂投加量、电位和反应时间等操作参数对主要污染物去除率的影响。污染物去除率随PAC投加量和外加电压的增加而线性增加。投加100 mg/L PAC，外加电压40 V，COD和BOD_5去除率均在99%以上。实验表明，化学和电化学技术处理屠宰废水是有效的。因此，联合工艺被推断为是上级单独电凝聚去除有机和无机化合物从牛屠宰场废水。
Slaughterhouse wastewater contains various and high amounts of organic matter (e.g., proteins, blood, fat and lard). In order to produce an effluent suitable for stream discharge, chemical coagulation and electrocoagulation techniques have been particularly explored at the laboratory pilot scale for organic compounds removal from slaughterhouse effluent. The purpose of this work was to investigate the feasibility of treating cattle-slaughterhouse wastewater by combined chemical coagulation and electrocoagulation process to achieve the required standards. The influence of the operating variables such as coagulant dose, electrical potential and reaction time on the removal efficiencies of major pollutants was determined. The rate of removal of pollutants linearly increased with increasing doses of PACl and applied voltage. COD and BOD5 removal of more than 99% was obtained by adding 100 mg/L PACl and applied voltage 40 V. The experiments demonstrated the effectiveness of chemical and electrochemical techniques for the treatment of slaughterhouse wastewaters. Consequently, combined processes are inferred to be superior to electrocoagulation alone for the removal of both organic and inorganic compounds from cattle-slaughterhouse wastewater.
