【摘要】：通过对微波协同二次负载改性活性炭工艺处理模拟印染废水的研究及在微波连续流中的初步应用,为下一步该工艺应用于微波连续流反应器中提供理论依据.主要考察了改性活性炭的投加量、微波辐照时间、微波功率、废水pH和废水初始质量浓度的变化对处理效果的影响.结果表明:色度的去除率随改性活性炭的投加量增加而增加,随微波时间增长而增加,随微波功率的上升而增加;对TOC的去除率总体维持在80%左右;脱氮率随着条件的变化有增有减;除磷效果在碱性条件下明显优于在酸性条件下.该工艺用于连续流中效果良好,TOC和色度去除率达75%.
[Abstract]:Through the study on the treatment of simulated printing and dyeing wastewater by microwave assisted secondary loading modified activated carbon process and its preliminary application in microwave continuous flow, the theoretical basis is provided for the further application of this process in microwave continuous flow reactor. The effects of the dosage of modified activated carbon, microwave irradiation time, microwave power, pH of wastewater and initial mass concentration of wastewater on the treatment effect were investigated. The results showed that the removal rate of chroma increased with the increase of the dosage of modified activated carbon, increased with the increase of microwave time, and increased with the increase of microwave power, and the removal rate of TOC was about 80%. The nitrogen removal rate increased and decreased with the change of the conditions, and the phosphorus removal effect was obviously better in alkaline than in acidic conditions. The process is used in continuous flow with good TOC and chromaticity removal efficiency of 75%.
