摘要
松香基桥联剂使石蜡基熔模的涂挂性发生了质的改变和提高。用破乳 - Fenton氧化法联合处理高浓度有机物松香乳化液废液。 COD去除率高达 99% ,出水达到排放标准。文中讨论了 H2 O2 、Fe2 + 加入量及 p H值对去除 COD的影响。
The slurring ability of the waxpattems was improved effectively by coating the rosin solution as cross-liking agent.Organic wastewater containing high concentration of rosin and other organic compounds was treated using emulsion-breaking combined with fenton catalytic,a rate of COD removal was up to 90%,the outflow quality reached the discharge standards.Effects such as the amounts of H 2O 2?Fe 2+ added and pH on COD removal were discussed.
