Treatment of city's common waste to produce organic fertilisers

机译:处理城市普通废物以生产有机肥料

摘要

The method utilises the process of oxidation - hydrolytic destruction in alkaline environment. Solid waste material is chopped into small pieces, mixed with water to form a pulp, and alkaline solution is added as the main reagent. Liquid waste material may also be mixed in the pulp. The materials are heated until a self supporting reaction starts. Air is also blown to the pulp to provide necessary oxygen for the oxidation reaction and assist mixing. During the reaction a solid sediment is formed. Upon completion, the materials are cooled down and the sediment is separated from the liquid solution which is in itself a useful fertiliser. The reaction ensures full extraction of heavy metals.
