Abstract: The user experience, community management situation and sewage pipe network of Beijing community were investigated, which the kitchen waste crusher was centralized installed. The results showed that both the household sewer pipes and community pipes clogged in the large-scale and centralized installed investigation communities in Beijing. The effluent of buffer pool (septic tank) in the investigation communities exceeded the standard. Combined with the status quo of sewage pipelines and sewage treatment capacity in Beijing, it was not recommended to popularize the kitchen waste crusher in urban built-up areas and rural areas. The new community should have a surplus of rain and sewage diversion and sewage treatment plant operation, and the establishment of kitchen waste discharge system should meet the relevant engineering and technical standards before large-scale use of kitchen waste shredders. For communities that had installed kitchen waste shredders,oily food waste recommended to be unified recycling.

Key words: kitchen waste, kitchen waste shredder, sewer
