Abstract:

A plastic mixture construction technology using MBER(material becoming earth into rock)soil stabilizer is introduced and the water quality of a solidified soil cistern using the technology is analyzed. Rainwater was harvested in July, 2012. Water quality of runoff and cistern water after storage was measured, including turbidity, chemical oxygen demand(COD), total nitrogen, nitrate, and ammonia. Results show that pollutant concentrations in runoff decreased with time, indicating that runoff in the early time should be removed. Nitrate concentrations in cistern water increased after storage, while the remaining parameters decreased. Measured pollutant concentrations did not exceed the limit according to the standard for drinking water in China. It can be concluded that the solidified soil cistern with plastic mixture construction technology can provide available water for domestic use.

介绍了一种利用MBER土壤固化剂作为建筑材料的塑性施工工艺, 并分析了利用该工艺施工的土壤固化剂蓄水装置的水体水质状况.试验于2012年7月收集集流面径流, 并进行后期贮存.采集的集流面和窖水水样的监测指标包括浊度、COD、总氮、硝酸盐和氨氮.结果表明, 集流面径流中污染物含量呈现出随降雨历时增加而逐渐减小的变化趋势, 因此降雨初期阶段的雨水应该弃用.贮存窖水中硝酸盐浓度呈现随贮存时间增加而逐渐增大的变化趋势, 而其余污染物浓度均呈现随贮存时间增加而逐渐减小的趋势.上述指标的监测结果均未超过国家饮用水卫生安全标准.研究表明该种装置可用于提供家庭用水.
