Abstract  A new kind of wastewater treatment system which used soil as the main substrate , multi-soillayering system , has been developed in Japan . It is composed of soil mixture block layers arranged in a brick-like pattern and water‐permeable layer .It has many advantages compared with other land treatment systems , such as preventing clogging , increasing hydraulic loading rate , enhancing the purification ability of soil , et al . This paper summarized the structure , mechanism and application of multi‐soillayering system , to provide a reference for the future use of multi-soil-layering system in China .

多基质土壤混合层技术研究应用

多基质土壤混合层(multi‐soil‐layering , MSL)技术是由日本开发的一项以土壤为主要基质的新型污水处理工艺,该工艺净化区主要由土壤混合层和通水层交叠成层排列而成.MSL 技术在污水处理上具有其他常规以土壤为基质的污水处理技术所不具有的优势,如不易堵塞、系统水力负荷大、增强土壤的净化能力等,并且已在生活污水、餐饮废水及微污染河水处理上进行了研究应用.本文从MSL 技术的系统结构、作用机制及其应用等方面进行了阐述,为该技术在我国的研究应用提供参考依据.
