Problems solved by technology

[0005] After the recovered sewage is added to the ball mill, the thixotropy of the slurry will be serious, and the milder ones will also have the problems of slowing down the flow rate of the slurry and poor fluidity. At the same time, the fineness of the slurry will become larger. In order to achieve Mud with the same fineness has to increase the running time of the ball mill. In order to solve the problem of ball mill efficiency decline and mud performance deterioration, the only way to increase the amount of mud debonding agent, water reducer, etc., increase the water content of the mud, Prolong the ball milling time and increase the energy consumption and increase the cost to solve the problem

Embodiment 1

[0020] Follow the steps below for ceramic wastewater treatment:

[0021] S1. Separate several pools in the original sewage treatment system as special pools for ball milling water, and the sewage is injected into the pool through a special channel;

[0022] S2. Install a medium-sized water tank with a mixer on the special water channel, and install a tap water outlet on the lower half of the water tank;

[0023] S3. Add Al in the water tank 2 (SO 4 ) 3 And transformed into an aqueous solution with a concentration of 27wt%;

[0024] S4. When the sewage is poured into the ball mill special pool, turn on the faucet under the water tank to evenly add Al to the sewage flowing through 2 (SO 4 ) 3 Aqueous solution, adding 0.5L Al per ton of sewage 2 (SO 4 ) 3 Solution, make the pH value of sewage reach 6.0~6.5.

[0025] This treated sewage is used in the production of ball-milled ceramic slurry and compared with new industrial water, as shown in the following table:

Abstract

The invention relates to a sewage treating method, in particular to a ceramic sewage treating method. The ceramic sewage treating method comprises the following steps: adding an Al2(SO4)3 solution in sewage; and enabling the pH value of the sewage to reach 6.0-6.5. The concentration of the Al2(SO4)3 solution is 25-30wt%; and the use amount of the Al2(SO4)3 solution is as follows: 0.3-0.8 L of the Al2(SO4)3 solution is added in every ton of the sewage. The method is simple and economic, on the promise of guaranteeing quality of sewage treatment and atmospheric emission, the sewage is modified secondarily, and therefore, negative effects to properties of ceramic slurry are eliminated.

Description

Technical field [0001] The invention relates to a sewage treatment method, in particular to a ceramic sewage treatment method. Background technique [0002] Ceramic tile manufacturers consume a lot of industrial water during the production process, and at the same time produce almost the same amount of industrial sewage. These sewage, at the beginning, contain a large amount of sand, glaze, chemical materials, abrasive particles, etc. to solidify and suspend Things. After they undergo a specific liquid-solid separation and purification process, the solidified material is separated from the water, and the separated water can be reused in the production of the enterprise, so that the water is repeatedly used again and again. The amount of water added to the carcass raw material into the ball mill accounts for about 80% of the total waste water recycling. [0003] However, in actual production, various ceramic tile manufacturers will encounter such a thorny problem: that is, the per...
