Embodiment 1

[0034] Embodiment 1: a method for recycling waste water containing slag in a stone processing process, comprising the following steps:

[0035] Step 1: After settling the water containing stone powder produced by stone processing, the water and the sediment at the bottom are preliminarily separated. In this embodiment, the sediment at the bottom is wet stone powder. Then the sediment at the bottom is passed into the tunnel furnace for baking to obtain semi-dry stone powder. In this embodiment, the moisture content of the semi-dry stone powder is 10%, and the mesh number of the semi-dry stone powder is between 32 and 400 mesh.

[0036] Step 2: put the semi-dry stone powder and molten paraffin into the blender according to the weight ratio of 1:3.5 and stir evenly, the stirring temperature is controlled at 65±5°C, and the stirring time is 5min to obtain the paraffin-stone powder mixture. In this embodiment, the raw material of the molten paraffin is No. 54 paraffin.

Embodiment 2

[0038] Embodiment 2: A method for recycling slag-containing waste water in a stone processing process. The difference from Example 1 is that the moisture content of the semi-dry stone powder obtained in step 1 is 13%; The weight ratio of paraffin wax is 1:4.

Embodiment 3

[0039] Embodiment 3: A method for recycling slag-containing waste water in a stone processing process. The difference from Example 1 is that the moisture content of the semi-dry stone powder obtained in step 1 is 15%; The weight ratio of paraffin wax is 1:5.

Abstract

The invention relates to the field of stone waste treatment, and particularly discloses a recycling and reusing method of slag-containing wastewater in a stone processing process, wherein the method comprises the following steps: step 1, settling stone powder-containing water generated by stone processing, separating the water from bottom sediments, and then introducing the bottom sediments into a tunnel furnace for baking to obtain semi-dry stone powder; step 2, putting the semi-dry stone powder and molten paraffin into a stirrer according to a weight ratio of 1:(3.5-5), and uniformly stirring to obtain a paraffin-stone powder mixture; and step 3, introducing the paraffin-stone powder mixture into a candle mold to be subjected to injection molding, and cooling to obtain the candle. By means of the method, the stone powder can be recycled, the current stone powder treatment difficulty is solved, the gain effect can be achieved on an existing candle, and two purposes are achieved.

Description

technical field [0001] The present application relates to the field of stone waste treatment, more specifically, it relates to a method for recycling waste water containing slag during stone processing. Background technique [0002] As a material, stone is widely used in indoor and outdoor decoration design, curtain wall decoration and public facilities construction, tombs, laundry pools and other fields. At present, the common stone materials on the market are mainly divided into natural stone and artificial stone. Among them, natural stone is divided into slate and granite according to the quality of physical and chemical properties; artificial stone is divided into terrazzo and synthetic stone according to the process. [0003] The industrial production process of stone is nothing more than drilling, grinding, polishing and other main processes, and a large amount of stone powder will be produced in these processes, and these stone powder will flow to the settlement alon...
