摘　　要：地沟式污水土地处理系统,是自然生态净化与人工工艺相结合的小规模污水处理回用技术。该技术以其设备简单、基建投资少、操作管理方便、能耗低,以及再生水重复利用而具有广阔的发展前景。以贵州省环科院内地沟式土地处理中试装置为例,探讨了地沟式污水上地处理系统细菌分布关系以及微生物活动对氮的脱除效果。Under ground-ditch-patter soil treatment is a miniature circle-using technique combined manual work with self-purification. As lost cost, easy operation and management, this technique is practical and have more chances for development. This paper introdrces new advances in land treatment technology, discourses the relationship between N removing effects and the distribution of bacteria in under ground-ditch-pattern soil treatment.
