摘 要:污水土地处理系统具有运行处理成本低、设备少、管理简单、处理效果稳定、便于就地回用等特点。填料是污水土地处理系统的重要组成部分,在土地处理系统对污水的净化过程中起着关键作用。试验共选择5种生物填料砖块、混凝土块、煤渣、陶粒、碎石进行了研究。结果表明,表面粗糙、孔隙率高的煤渣对各种污染物的去除效果最好,CODCr平均去除率为56.76%,BOD5平均去除率为86.33%,TN平均去除率为25.70%,TP的平均去除率为56.25%。陶粒、碎石、混凝土、砖块的去除效果依次降低。Wastewater land treatment system has many characteristics, such as low-cost, less equipments, stable management and easy to reuse etc. The carrier is an important part of the waste water treatment system, and it plays a vital role in the purification process of land treatment system. There were five kinds of biological carrier for studying, which were bricks, concrete block, cinder, bio-ceramic and detritus. The results showed that the cinder with roughness-surface and high-porosity had the best removal efficiency of various pollutants. The CODcr average removal of cinder was 56.76%, BOD5 average removal was 86.33%, TN average removal was 25.70%, and TP average removal was 56.25%. The removal efficiency of bio-ceramic, detritus, concrete and bricks were reduced in turn.
