摘要
为了缓解畜禽粪污带来的日益严重的环境问题,本文从“以废止废”的资源化利用角度出发,采用微波法制备了牛粪/钢渣复合活性炭,同时对养殖废水进行降解研究,探究了不同反应条件下养殖废水中化学需氧量(COD)的降解率。结果表明:适量的钢渣掺混比可以提高COD降解率,以抵消复合炭比表面积降低带来的消极影响;COD的降解率随微波功率和微波时间的增加会呈逐渐上升的趋势;在最优反应条件下,养殖废水的COD降解率最高为55.4%,处理单位体积养殖废水的运行成本约为384.98 CNY。
In order to alleviate the increasingly serious environmental problems caused by livestock and poultry waste,this paper adopts the microwave method to prepare the composite activated carbon of cow dung/steel slag from the perspective of resource utilization of"Treating waste of waste",and at the same time conducts degradation research on farm wastewater to investigate the degradation rate of chemical oxygen demand(COD)in farm wastewater under different reaction conditions.The results showed that:the appropriate amount of steel slag mixing ratio can improve the COD degradation rate to offset the negative impact of the reduction of the specific surface area of composite carbon;the degradation rate of COD with the increase of microwave power and microwave time will show a gradual increase in the trend;in the optimal reaction conditions,the COD degradation of aquaculture wastewater was up to 55.4%,and the operating cost of treating the unit volume of aquaculture wastewater was about 384.98 CNY.
