Description

Kitchen waste separating and collecting system

Technical Field

The invention relates to the technical field of garbage collection, in particular to a kitchen garbage separating and collecting system.

Background

The kitchen waste is food waste formed in the process of living consumption of residents and mainly comprises residues generated in food processing before meals, and leftovers discarded after meals. The kitchen waste has higher water content, high organic matter content, rich nutrition and higher utilization value, but is easy to rot and deteriorate, generates leachate and odor, is easy to generate viruses and pathogenic bacteria, causes the spread of the germs and causes harm to the human health and the environment.

Kitchen waste is also the main component of household garbage, and the key for solving the problem of household garbage disposal is to carry out independent treatment and collection on the kitchen waste. At present, domestic kitchen garbage collection and treatment is generally carried out by the following scheme: through solid-liquid separation of the vegetable washing basin, liquid flows into the septic tank through a sewer for preliminary treatment and then is merged into a municipal sewage pipe network; the solid kitchen waste is collected, packed and put into a garbage classification box of a community, and then transported to a garbage disposal plant for landfill or composting by sanitation. Because the kitchen garbage contains grease which can be used for preparing biodiesel, the grease flows into a sewer along with liquid in the treatment mode, so that not only is the burden caused by municipal sewage treatment, but also the resource waste is caused; the turnover process of the solid kitchen garbage is carried out for at least one day, during the turnover and collection process, the garbage leachate of the wet garbage is easy to drip, and the foul gas generated by the putrefaction and deterioration of the garbage leachate also extremely pollutes the surrounding environment

In addition, a scheme for collecting kitchen waste by adopting a vacuum pipeline is also provided: a crusher and an interface valve are installed in each household, and crushed kitchen waste is collected through a vacuum pump station and a pipeline, and then oil separation and filter residue resource utilization are unified. However, this solution is implemented with the following problems: 1. the manufacturing cost is high; 2. the system is difficult to operate normally, newly built residential areas in China are all high buildings at present, for example, a building with 30 floors and one stair and eight households is used, even if one vacuum pump station is arranged in one building, at least 240 interface valves connected with the vacuum pump stations are arranged, as long as one household has air leakage fault, vacuum cannot be built, a whole building sewage discharge system is broken down, in addition, kitchen garbage is basically thrown in one hour or two hours, the interface valves are started too much at the same time, the vacuum degree of the system is insufficient, and accordingly sewage cannot be discharged.
