| 摘 要： | 污水污灌一直是灌区农业灌溉的一种重要形式,但由于系统接纳污水的成分复杂,也常常带来灌溉风险。主要针对污灌水体中的硫离子给水稻带来的危害,提出利用光敏剂快速除硫的可能性。土柱实验发现,光敏剂在土壤中的吸附符合Langmuir等温式Qeq=3.81Ce/(1+1.293Ce),当其加入量为10μmol/L,光照强度为3000lx时,S2-的去除率为87.5%;光照强度为2000lx时,S2-的去除率为78.1%,而完成该过程仅需要30min,并且光敏剂也不会给环境带来二次污染。

| Abstract: | Wastewater irrigation is a sort of watering in irrigation area, with some risks because of complicated wastewater components. A new fast removal method with photosensitive RO was proposed to minimize the impact of sulphur ion in irrigation water on rice. Soil tests showed absorbing of RO in soil was in accordance with Langmuir’s law. The removal efficiency of sulphur was 87.5% at RO addition 10 umol/L, lighting time 30min under 30001x, while 78.1% under 20001x, and without photosensitive pollution. |
