Recycling method for cast-in-situ terrazzo floor polishing waste slurry

Abstract

The invention relates to a recycling method for cast-in-situ terrazzo floor polishing waste slurry and belongs to the technical field of building terrace green environment-friendly construction. The recycling method comprises the following steps: preparing a waste slurry collecting filtering precipitation separation mechanism; digging a box pit for placing the waste slurry collecting filtering precipitation separation mechanism; paving a waste slurry discharging pipe and a clean water recycling guiding pipe along an outer wall of a wall of a building; arranging a coffer for stopping slurry escaping at a ladder port and a door opening of the floor terrace of the building in which the polishing construction operation is performed; and recycling and reusing the waste slurry. The recycling method has the advantages that: the cost is saved and the manpower investment for digging and / or building on the terrace is reduced; the original address is free from any pollution, thereby achieving environmental protection; water in a clean water reusing tank can be used for polishing, so that the valuable water resource is saved; and the filtered slag and precipitates can be used for constructing a decorative wall of the building, so that the best use of the slurry is achieved and the secondary pollution is eliminated.

Description

technical field [0001] The invention belongs to the technical field of green and environment-friendly construction of building floors, and in particular relates to a method for recovering waste slurry from polishing of cast-in-place terrazzo floors. Background technique [0002] The cast-in-place terrazzo floor is a composite floor material with cement as the main raw material. It is widely used in hospitals, factories, institutions, schools, commercial places, In buildings such as cultural and entertainment venues, airports, stations and docks, and even canteens. However, in the process of polishing the terrazzo floor (also called polishing in the industry), on the one hand, a large amount of water resources are consumed, and on the other hand, a large amount of waste slurry is generated. If the waste slurry is discharged directly without treatment, it will cause environmental pollution, such as river siltation, municipal facility pipe network blockage, damage to soil and ...

AI Technical Summary

Problems solved by technology

[0004] There are the following deficiencies in the above-mentioned way of intercepting the waste slurry produced in the grinding process: First, because the waste slurry is directly excavated on the ground by the waste collection pond Collected, and because the waste collection pond excavated directly on the ground has the property of being non-movable and disposable, it is necessary to excavate the waste collection pond when the polishing construction in one place is completed and transferred to another place for construction, resulting in Waste of manpower, financial resources and material resources; Second, due to the large amount of excavation of waste collection ponds and the need for backfilling after the completion of the project, especially permanent pollution of the waste collection pond area will be caused, because the waste collection pond waste site The soil at the site is destroyed, which not only causes a waste of labor resources but also produces local pollution; third, because the upper layer of clean water in the waste collection tank cannot be reused for grinding construction, the waste of water resources is serious, which is in line with the current advocacy of the whole society. The energy-saving and energy-saving economic spirit is contrary to the spirit; Fourth, because the sediment accumulated in the waste collection pond needs to be fished out from the waste collection pond after the project is completed or during the grinding construction process, and transported to the place permitted or designated by the environmental protection department for processing Landfill, or treat in a specific way, so not only increase the cost of transport capacity, but also produce secondary pollution

[0005] From the above description, it can be known that building the waste collection pond directly on the outdoor floor of the grinding construction site is undoubtedly a measure to cure the symptoms rather than the root cause, and so far In the absence of effective countermeasures, there are no other options
