Embodiment Construction

[0018] A comprehensive treatment method for construction waste. First, the construction waste generated in the demolition of buildings, house renovation and road reconstruction is transported to the treatment site by car, and then the directly recyclable substances in the construction waste, such as metal materials, wood materials and plastics, are manually removed. The materials are sorted and classified, and directly supplied to the corresponding companies for processing.

[0019] For large pieces of waste concrete, waste bricks, marble, ceramics, glass, gypsum products, slag and mud in construction waste, use a large hammer or crusher to crush them to a size that the crusher can crush, generally less than 100 Then use a stone crusher to crush the stones and sand required for construction, and then use a multi-layer grading sieve to classify the above mixture into coarse stones (25-50 mm) and fine stones (below 25 mm), which meet the construction standards. Coarse sand, fin...

Abstract

An integrated approach to construction waste, first the construction waste including demolished the buildings, housing renovation and improvement of road will be sent to the garbage handling sites by the car, and then the construction waste that could be directly in the use of renewable materials, such as metal, wood and plastic materials use artificial methods for separating classified, then supplying company directly for the corresponding treatment. The bulk of concrete waste, scrap brick, marble and other materials, using the large broken hammer or crusher broken to the size that mill can crush, typically less than 100 mm, and then using stone crusher breaking these stones and sand until the construction standard, then grading said mixture into big stones, small stones, coarse sand and fine sand, argillo-arenaceous ground and other breeder material using multi-layered grading sieve. The production water uses activated carbon hyperfiltration cleaning domestic sewage which can be used cyclically, it can save water and can prevent the reemission of sewage water polluting environment.

Description

technical field [0001] The invention relates to a method for environmentally friendly and harmless treatment and resource recovery of construction waste, especially for the resource recovery of waste concrete, waste bricks, marble, ceramics, glass, gypsum products, slag and mud residue in construction waste and harmless comprehensive treatment methods. Background technique [0002] In the process of rapid development and construction of cities and small towns, the disposal of construction waste as an accessory product of the construction of cities and small towns has become a common problem faced by city builders and city managers. According to the requirements of urban construction, every new planning and layout of urban construction will involve the demolition of buildings, house renovation and road reconstruction, which will bring a large amount of urban construction waste. Currently, there are generally two types of treatment methods. One is for small cities, which is t...
