METHOD FOR STORAGE AND PROCESSING OF SOLID ORGANIC HOUSEHOLD WASTE AND A SYSTEM FOR ITS IMPLEMENTATION Russian patent published in 2018 - IPC B09B1/00 

FIELD: municipal engineering.

SUBSTANCE: invention relates to the field of housing and communal services and can be used for underground storage of solid household waste (SHW) of organic origin. Method of storage and processing an organic solid waste consisting in the fact that the required dimensions of the reservoir, which is a foundation ditch for storage and processing of organic solid waste taking into account the characteristics of the soil, near the city. Bottom of the foundation ditch and its side walls are poured with concrete to produce a reinforced concrete structure, the waterproofing of the concrete layer is performed, the bottom of the tank is made with a slope, at the bottom of the tank a water intake for collecting filtrate and water is installed, which is connected with a pump to the filter for water purification. On the perimeter of the tank, a system of pipelines is installed to remove biogas, which is connected to a device for cleaning biogas. Tank is filled with a part of solid waste, covered with waterproof material and covered with a layer of soil, after which the specified stages of loading part of the waste are repeated and they are closed until the reservoir is filled. Further in the course of operation, the filtrate and rainwater are pumped from the water intake for further processing. Produced biogas is transported through a system of pipelines for biogas extraction to a device for processing and cleaning biogas from water. Formation of biogas is monitored and, upon its complete cessation, a laboratory analysis of the rotten wastes in the tank is carried out to confirm the absence of hazardous and harmful substances in it, after, the tank is opened, the waste is taken out and processed for further use. Method of storage and processing of SHW of organic origin is carried out with the help of a system.

EFFECT: ensuring multiple use of one tank for storage and processing of solid organic waste, and also ensuring safety of further use of the rotten waste after its withdrawal from the tank.
