什么是septic system?

Septic system是一个和人们日常生活有着密切关系的短语,尽管你几乎看不到它的存在。根据West Virginia University的定义:”A septic system is a highly efficient, self-contained, underground wastewater treatment system. Because septic systems treat and dispose of household wastewater onsite, they are often more economical than centralized sewer systems in rural areas where lot sizes are larger and houses are spaced widely apart.” 按照这个解释,可以看出septic system是指:地下废水处理系统,其具有高效、自给的特点。在偏远地区,由于房屋占地面积更大、且地理上更为分散,septic system相比集中式的下水管道污物处理系统更加经济。在这个词组里,septic的意思是:A drainage system incorporating a septic tank.(含有腐化池的排水系统),注意Oxford Dictionary指出,septic所具有的这层含义主要用于北美地区(North American)。
