矿化垃圾反应床处理印染废水系统驯化效果

摘要

为开发廉价的吸附剂和生物载体，将矿化垃圾资源化利用，在实验室建立矿化垃圾反应床处理模拟染料废水，考察容积负荷及水力负荷渐增法对反应床内微生物的驯化效果。训化结束时，容积负荷渐增法出水中COD，NH3-N，TP，MB浓度分别为49.81，3.06，0.45，1.09 mg·L-1，驯化时间越长出水效果越稳定，去除率维持在98%以上。水力负荷渐增法驯化结束时出水COD，NH3-N，TP，MB分别为81.00，4.39，0.15，1.38 mg·L-1。结果表明两种驯化方法均可取得较好的驯化效果，容积负荷渐增法去除效果优于水力负荷渐增法。在矿化垃圾反应床处理染料废水应用中，将选用容积负荷渐增法对矿化垃圾进行驯化，同时需保证一定的训化时间。%For the development of low-cost adsorbent and biological carrier, and the mineralized waste resource utilization, this study established the aged refuse reactor with simulated dyeing wastewater in the laboratory to in⁃vestigate increasing volume loading and hydraulic loading method for acclimated microorganisms inside the reac⁃tor. At the end of the training, effluents of COD, NH3-N, TP, MB were 49.81, 3.06, 0.45, 1.09 mg·L-1 respectively for the increasing volume loading method. The effluent was more stable with the time being longer, and removal rate of the pollution remained above 98%. Effluents of COD, NH3-N, TP, MB were 81.00, 4.39, 0.15, 1.38 mg·L-1 at the end of increasing hydraulic loading method. The results showed that the two methods can achieve better ac⁃climation effect, and it is better for the increasing volume loading than the hydraulic loading method. For the appli⁃cation of aged refuse reactor on dyeing wastewater, volume loading method can be chosen and a certain degree of training time is needed.
