摘要:
将降解酚类化合物的高效工程菌固定在活性炭上,采用臭氧-固定化生物活性炭(O3-IBAC)工艺处理煤气废水。研究证明:在臭氧投量为18mg/L ,接触时间为2 0min时,臭氧可以改变水中有机物的结构,但是有机物的总量没有明显的变化。当煤气废水进水COD、酚类的质量浓度分别为5 0 0mg/L、95mg/L左右时,采用O3-IBAC工艺对两者的去除率可以分别达到80 %、92 %以上。系统运行6个月后,IBAC上工程菌分布均匀,炭数量可达6 .1×10 3cfu/g ,而且工程菌在种类上仍然占优势。同时,运用生态位理论解释了工程菌可以长期稳定存在,且保持较高的生物活性的原因
Abstract:
When engineering bacteria that can effectively degrade phenol are immobilized on activated carbon, immobilized biological activated carbon( IBAC) comes into being. A combinatorial process of ozone and IBAC is applied in treating coal gas wastewater. Under the condit ion that the ozone dose is 18 mg/ L and the ozone oxidation time is 20 min, the oxidation contributes litt le to the removal of total organic carbon ( TOC) , w hile it changes the characteristics and the structure of the organic substance in the wastewater. Making use of ozone- IBAC t reatment, w hen the inflow contains 500 mg/ L COD and 95 mg/ L phenol, their removal rates are higher than 80 % and 92 %. After 6 months of operat ion, the engineering bacteria density keeps above 6. 1 @ 103 cfu/ g carbon and in dominant status, moreover, the engineering bacteria distribute uniformly on the activated carbon. The longterm steady viability and high biodegradat ion efficiency of the engineering bacteria are discussed in terms of the theory of ecological place.
