Abstract

Despite of the positive effect of the growth of Batik industry in Yogyakarta to economy, the waste water pollution of dying process of Batik industry has negative impact to environment. Initial measurement of COD, BOD and TSS of waste water resulted from dying process of Batik that implemented Naphtolat and Diazo Salts were exceeded the threshold. Hence, this study implemented electrocoagulation for processing Batik wastewater. The results showed that the range of the electrodes and the voltage are give effect to the reduction in COD, BOD, and TSS in liquid sewage electrocoagulation process in dye wastewater in batik industry "Rara Djonggrang". The optimum electrode range on TSS and BOD reduction in the optimum is  a range of 2 cm with 85.71% of TSS decrease and 7.02% of BOD reduction, while the optimum COD reduction in a range of 4 cm with a decrease of 92.18%. The voltage give effect to decrease in TSS and COD are 15 V, with 85.71% of TSS decrease and 92.18% of COD reduction. The most optimum of BOD value is ​​using voltage variation 10 V and a range of 6 cm. Electrocoagulation process with using aluminum electrode is the most appropriate for treating Diazol Salt sewage.
电絮凝对降低蜡染工业废水COD、BOD和TSS的影响
尽管日惹蜡染工业的发展对经济产生了积极的影响,但蜡染工业染色过程中的废水污染对环境产生了负面影响。采用萘酚盐和重氮盐处理蜡染废水,初始测定COD、BOD和TSS均超过阈值。因此,本研究采用电絮凝法处理蜡染废水。结果表明,电极和电压的选择范围影响了“拉仲让”蜡染工业染料废水电絮凝工艺中COD、BOD和TSS的降低。最佳电极对TSS和BOD的最佳还原范围为2 cm, TSS降低85.71%,BOD降低7.02%,而COD的最佳还原范围为4 cm,降低92.18%。降低TSS和COD的电压为15 V, TSS降低85.71%,COD降低92.18%。最佳的BOD值是使用电压变化10 V,范围为6 cm。铝电极电絮凝法是处理二氮唑盐废水的最佳工艺。
