摘　　要：针对现代煤化工废水生化处理系统运行不稳定,抗负荷能力差等诸多问题,通过将煤化工固废复合物改性使其成为生物载体,从而增强生化系统的稳定性,提高生化的出水水质。利用不同酸(盐酸和柠檬酸)改性得到的生物载体,对比微生物在有无投加载体的情况下对COD的降解去除效果。试验表明,煤化工固废复合物在经过改性之后,是一种良好的微生物载体,可有效提高生物的稳定性及其去除污染物等效果。Due to the unstable operation and poor load resistance of the biochemical treatment system of modern coal chemical industry wastewater,the solid waste compound of coal chemical industry is modified to become a biological carrier,so as to the stability of the biochemical system is enhanced and the biochemical effluent quality is improved.The biological carriers modified by different acids(hydrochloric acid and citric acid)were used to compare the degradation and removal effects of COD by microorganisms with or without loading agents.The test shows that the coal chemical solid waste complex is a good microbial carrier after modification,which can effectively improve the biological stability and the pollutant removal effect.
