摘　　要：通过光催化的基础实验,确定光催化降解染料的工艺条件是:光源为低压汞灯,光强为6.0mw/cm2,光照时间为6h,染料初始浓度为50～80mg/L,光催化剂用量为250g/L,pH值为4.0。通过光催化-光合细菌法和光合细菌法处理印染废水相比较,两者的CODcr去除率分别为50％和30％。Through a basic experiment of photocatalysis, the technological conditionas of photocatalysis degradable dye are as follows: light source; low potential lamp; light intensity; 6. 0mW/cm2; exposure time: six hours; initial dye concentration: 50-80mg/L; amount of photocatalyst: 250g/L; pH:4. 0. We compare the two methods for printing and dyeing wastewater treatment; photocatalysis-photosynthesis bateria and photosynthesis bateria were compared. The remove rate of CODcr for the former is about 50% while 30% for the latter.
