Waste treatment method adopting brick making process

Abstract

The invention relates to a technology for making environment-friendly composite pavement bricks and in particular relates to a waste treatment technology for making composite pavement bricks by utilizing domestic wastes and construction wastes. The waste treatment technology is characterized by drying, screening and grinding the domestic wastes to prepare solid wastes, grinding the construction wastes into powder or fine granules after screening the construction wastes, grinding fluorine gypsum and fly ash into powder, adding 25-35% of domestic wastes, 25-35% of construction wastes, 10-15% of fly ash, 15-20% of fluorine gypsum, 5-10% of cement, 3-5% of aluminium potassium sulfate and 2-5% of acrylic construction gelatine powder to a stirrer and fully stirring the materials uniformly, then sprinkling water and stirring the materials until the raw materials are moist and loose and have certain viscosity, throwing the raw materials into a brick making machine to undergo press forming, curing the formed bricks for 5-7 days in a storeroom with relatively stable temperature and humidity, and delivering the bricks.

Description

technical field [0001] The invention relates to a method for treating garbage, in particular to a method for treating garbage by using domestic garbage and construction waste to make bricks. Background technique [0002] At present, landfill and incineration are commonly used to deal with municipal solid waste. Both landfill and incineration will cause different degrees of pollution to the environment. Landfill pollutes groundwater resources and occupies a large amount of land. Garbage incineration will pollute the atmospheric environment. . In the past, there was a garbage treatment technology that used garbage to make bricks. However, due to the poor water resistance of the finished products and the tendency to return to brine and deform, it has not been popularized for a long time. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention provides a garbage treatment method using a brick-making process, and particularly relates to a ...
