  • 摘要: 在对我国家庭厨余垃圾的组成及性质、污水管道设计、污水处理厂运行状况的调查研究基础上,初步探讨了基于厨房垃圾粉碎机的家庭厨余垃圾减量及其对下水系统的影响。家庭厨余垃圾生成量(湿重)平均为152 g/(人·d),其中易降解的蔬菜水果垃圾占到77.8%。家庭厨余垃圾的COD:TN:TP=400.9:4.7:1,可能导致污水处理厂的总COD、TN、TP和氨氮理论提高量分别为66.70、0.86、0.18和0.43 mg/L,会在一定程度上缓解我国污水处理厂碳源不足的现状。厨房垃圾粉碎机使用后,人均用水最大增加量为1.5 L/(人·d),破碎时间短基本介于1~3.5 min之间。破碎后的厨余垃圾颗粒含水率高,密度略大于水,其在管道中起动的临界流速为0.02 m/s远小于0.6 m/s,故因厨房垃圾粉碎机使用引起的污水管网堵塞的可能性小。
    Abstract: In this study, the application of food waste disposers (FWD) for household kitchen waste (HKW) reduction and influence on sewer system were studied. The amount of HKW (wet weight) was estimated up to 152 g/(capita·d), 77.8% of which was comprised of easy biodegradable vegetables and fruits waste. The value of COD:TN:TP in HKW reached 400.9:4.7:1, so the HKW was supposed to be effective in solving the problem of carbon source shortage in Chinese WWTPs by raising the concentration of COD, TN and TP in sewage after mixing with 66.70,0.86 and 0.18 and 0.43 mg/L, respectively. The extra water consumption with FWD was up to 1.5 L/(capita·d). The kitchen waste's particle critical velocity was calculated to be 0.02 m/s that is much less than the code value of 0.6 m/s for the design of outdoor wastewater engineering and leads to less blockage in sewer system.
