AI Technical Summary

Problems solved by technology

This is because the polished brick sludge treated with iron-based flocculants contains iron elements, which are prone to color and dirt defects when used as raw materials to produce building materials
[0007] In addition, because most ceramic tile polishing / edging grinding heads use high-temperature resins as adhesives, there are many flocculent high-temperature resins in ceramic tile polishing wastewater, and these flocculent high-temperature resins can quickly form flocculants However, it also makes the obtained polished brick sludge poor in suspension and plasticity, which is not conducive to secondary utilization

Embodiment 1-15

[0027] The following table 1 is the formulation of flocculant components (mass percentage) for implementation 1-15.

[0028]

[0029] In order to obtain a better treatment effect, the various components in the above table are powder particles, and the particle size is preferably ≤2mm. In the above examples 1-15, the particle size of attapulgite is ≤1 mm, the particle size of the porous adsorbent is 0.5-2 mm, the aluminum salt is purchased industrial-grade raw material; the particle size of bentonite is ≤1.5 mm.

Embodiment 16-30

[0031] The present invention also provides a method for using the above-mentioned flocculant to treat ceramic tile polishing wastewater. Examples 16-30 use the flocculant provided in Example 1-15 to treat ceramic tile polishing wastewater. The treatment method is as follows:

[0032] Step 1): recycle waste water; recycle the ceramic tile polishing wastewater to the waste water pool, after stirring, put the ceramic tile polishing waste water into the treatment pool;

[0033] Step 2): Add flocculant; add flocculant according to the mass ratio of ceramic polished tile wastewater to flocculant: 100:0.5;

[0034] Step 3) clarification; the ceramic polished tile wastewater in the treatment pool is left to stand, and then the supernatant is drained to obtain the lower mud;

[0035] Step 4) pressure filtration; the slurry obtained in step 3) is subjected to pressure filtration treatment to obtain polished brick sludge.

[0036] For the above method, the amount of flocculant added in ...

Abstract

The invention provides a flocculant and relates to the wastewater treatment technology. The flocculant is prepared from the following components in percentage by mass: 25-55 percent of attapulgite, 20-55 percent of porous adsorbent and 5-45 percent of aluminum salt. With the adoption of the flocculant, ceramic tile polishing wastewater can be rapidly clarified, and meanwhile, mud at the lower layer is good in suspension property and is convenient in pressure filtration treatment, so that tile polishing mud prepared by pressure filtration is good in plasticity and can be secondarily utilized.

Description

technical field [0001] The invention relates to waste water treatment technology, in particular to a flocculant. Background technique [0002] In the production process of ceramic tiles, polishing is often required. "Polishing" refers to polishing, that is, polishing the surface of ceramic tiles with a polishing grinding head, the purpose is to repair the surface defects of ceramic tiles, repair warping, and obtain higher gloss; The side plate of the ceramic tile is ground to keep the edge line of the ceramic tile straight and the specification consistent with the setting. In the above polishing process, water is often needed to cool down and lubricate, and at the same time, water will also take away the debris generated by polishing to avoid dust. Therefore, ceramic tile polishing treatment will produce a large amount of waste water. At present, the method of treating the above wastewater is: firstly introduce it into the wastewater tank for precipitation; then let go of...
