Embodiment

[0015] Follow the steps below to dispose of construction waste:

[0016] (1) First properly crush the construction waste to be processed (construction waste containing concrete blocks, bricks, tiles, stones, residual mud, sand, muck, bamboo, wood, waste plastic boards, etc.), and then remove the metal Sorting and detection of bamboo, wood and plastic materials, and then pour the remaining materials into the cleaning pool with three-level sieve frame. The sieve holes of the three-stage sieve frame from top to bottom are respectively 10cm, 5cm, 1cm. Rinse with high-pressure pump water and stir mechanically, so that the mud and sand in the construction waste are quickly cleaned and separated into mud slurry, granules and lumps. From bottom to top, it is separated into mud slurry, small-grained sand and gravel, medium-grained sand and large-scale materials, which are discharged through the discharge ports of each layer respectively. The bulky materials are directly transported b...

Abstract

A comprehensive treating method for the building garbage includes such steps as proper breaking, separating metals, bamboo, wood and plastics out, adding the rest into a washing pool with three-class layered sieve, washing with water while stirring to separate silt sludge, sand and stone particles and big blocks from each other, multi-stage mechanical separation of silt sludge to obtain sludge and sand-stone particles, depositing sludge to become water and clay, drying clay, and cyclic use of water.

Description

technical field [0001] The invention relates to a method for processing and comprehensively utilizing construction waste. Background technique [0002] At present, construction waste is usually disposed of by landfill at home and abroad. For example, there are several construction waste landfills currently opened in Guangzhou and a landfill project to be built in Yongxing Village, Longgui, Taihe Town, Baiyun District, Guangzhou City. The 15.16 million cubic meters of construction waste storage, transportation and disposal field initially acquired 460 acres of land, and the government paid a huge amount of money. The service life is only 6 years. Therefore, the Guangzhou Municipal Government needs to continue to invest a large amount of funds in order to deal with construction waste, occupying a large amount of land resources, and will also have an impact on the environment, which is a continuous problem. At present, the treatment and management of construction waste in my c...
