Embodiment

[0028] See figure 1 with figure 2 The recovery method of the cast-in-place terrazzo floor polishing waste slurry provided by the present invention comprises the following steps:

[0029] A) Preliminary preparation, equipped with a waste slurry collection, filtration, sedimentation and separation mechanism 1, the waste slurry collection, filtration, precipitation and separation mechanism 1 includes a waste slurry collection box 11, a clean water reuse box 12 and a sedimentation box 13. In this embodiment, The height of the waste slurry collection tank 11, the clear water reuse tank 12 and the sedimentation tank 13 is preferably 1 m, and the length and width are 1.5 m, and they are all preferably made of glass fiber reinforced plastic. In order to ensure the strength and reflect a good reuse rate, the upper edge around the inner wall of the waste slurry collection box 11 is wrapped with a first reinforcing rib 112, and the upper edge around the inner wall of the clean wat...

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 ...
