| 摘 要： | 目的]研究造纸黑液和马铃薯淀粉废水混合废液对沙性土壤的改良作用，在解决废水环境污染问题的同时改善生态环境。方法]将不同体积比的混合废液（马铃薯淀粉废水：造纸黑液=1：1，2：1，3：1，4：1，5：1）经过常温发酵30d，通过对混合废液pH变化的研究，确定最佳混合比例及混合发酵条件，并考察处理后混合废液对沙性土壤的改良效果。结果]马铃薯淀粉废水与造纸黑液以体积比2：1比例混合，经过常温发酵15d后可得到稳定的pH接近中性的混合废液，将其以质量比1：4的比例施入沙性土壤，可提高沙性土壤的pH值，降低干容重，增加土壤有机质含量，有效提高土壤持水能力。结论]该研究对治理环境污染，废水资源化及生态环境建设具有重要意义。

| Abstract: | Objective] The experiment was designed to study the improving effect of mixed wastewater from paper making black liquor and potato starch wastewater on sandy soil.Its objective was to solve environmental pollution of wastewater and to improve ecological environment.Method] Mixed wastewater of different volume proportion(Potato starch wastewater:paper making black liquid= 1∶1,2∶1,3∶1,4∶1,5∶1) was fermented for 30 days and the changes of pH value was studied to determine the optimum mixture ratio and fermentation condition.The improving effect of mixed wastewater on sandy soil was studied.Result] The results showed that it could effectively counteract the alkaline of black liquor when the two kinds of wastewater were mixed with the volume ratio of 2∶1 and were fermented for 15 days.When the mixed wastewater was fertilized to sandy soil with the mass ratio of 1∶4,the dry bulk density were decreased while pH value and organic matter content was increased.And the water-retention capacity of sandy soil was also effectively improved.Conclusion]The research will have important meaning to reduce environmental pollution and to construct ecological environment. |
