粉碎后的厨余垃圾能否快速、有效地排至室外是衡量厨余垃圾排放系统性能好坏的重要指标。为了防止厨余垃圾排放对住宅排水系统产生不利影响,需要合理地选择排水系统。采用水龙头连续给水模拟实际厨余垃圾排放情况,对3种不同高度住宅的DN75和DN110伸顶通气排水系统开展厨余垃圾排放足尺试验研究,主要考察排水系统底部楼层的最大正压,并结合试验录像探索厨余垃圾排放对住宅排水系统的影响。研究发现,在相同的系统高度下,DN75伸顶通气排水系统底部最大正压比DN110伸顶通气排水系统底部最大正压大;在相同的立管管径下,排水系统越高,底部产生的正压越大。
Whether the kitchen waste after crushing can be quickly and effectively discharged to the outside is a measure of the performance of kitchen waste discharge system, an important indicator of good or bad. In order to prevent the discharge of kitchen waste adversely affecting the residential drainage system, the drainage system needs to be properly selected. The faucet continuous water supply was used to simulate the actual discharge of kitchen wastes. The full-scale experimental study was conducted on the discharge of kitchen wastes from DN75 and DN110 extensible aeration and drainage systems of three different height dwellings. The main positive pressure of the floor of the drainage system was mainly investigated and combined Test video to explore the impact of kitchen waste discharge on residential drainage system. The study found that under the same system height, the maximum positive pressure at the bottom of DN75 extensible aeration drainage system is larger than the maximum positive pressure at the bottom of DN110 extensible aeration drainage system. Under the same stand pipe diameter, the higher the drainage system, Positive pressure greater.
