厨余垃圾排放系统存水弯残留情况的试验研究

Study on Residue at Traps for Kitchen Garbage Drainage System

粉碎后的厨余垃圾通过建筑内部重力流污水管道进行排放,可以改善城市垃圾处理所面临的困境,但同时也会增加存水弯的堵塞隐患。针对存水弯的形式和安装高度在实验室内进行了相关排水实测,结果表明,要使存水弯中不产生残留,其上肢安装高度应在8 cm以内。通过对比还发现:在相同上肢安装高度下,S型存水弯对厨余垃圾的输送能力优于P型存水弯,其中S型存水弯宜采用两次180。拐弯。

can improve the c The drainage of crushed kitchen garbage through gravity flow sewage pipes in building urrent situation of urban garbage disposal, but it can also increase the blockage possibil- ity for the traps. In view of traps＇ forms and installation height, some related tests were conducted in the laboratory. The results showed that to prevent residues in the traps, the upper limb installation height should be within 8 cm. Under the same installation height of the upper limb, the delivery capability of the kitchen waste by S-type traps was better than that by P-type traps. Meanwhile, it＇ s wiser to choose the S-type traps with two 180° bends than those with two 135° bends when considering about the delivery capability.
