[0020] Preparation of filter material: According to the mass ratio of 4:3:2, mix 150-mesh river sand, river pebbles with a particle size of 2-3cm and 150-mesh rice wheat stone.

[0021] Treatment of wastewater from ceramic production:

[0022] According to the mass ratio of 80-90:1-3:2-4, put ceramic production wastewater, calcium oxide and citric acid into the treatment pool, stir for 30-40 minutes, stop stirring, and heat the treatment pool to 50-60°C , heated for 1 to 2 hours; after the heating, the mixture in the treatment tank was filtered, and the filtrate was collected. In parts by weight, 70 to 80 parts of filtrate, 30 to 35 parts of rice straw, and 20 to 25 parts of 100 mesh leeches were taken. Stone and 5 to 8 parts of trimethylsilane were put into the aeration tank, and stood at room temperature for 40 to 45 minutes; 45~55℃, stir at 120r / min for 10~15min, then stir at 13~18m 3 / min for aeration for 2 to 3 hours; after the aeration, cool to room temperature, put th...

Abstract

The invention belongs to the technical field of waste water treatment, and concretely relates to a method for processing ceramic production waste water. The method comprises the following steps: filtering ceramic production waste water, mixing the waste water with calcium oxide and citric acid, stirring a mixture, heating the mixture and insulating the mixture, filtering the mixture to obtain a filtrate, adding substances such as paddy rice straw and vermiculite for standing, adjusting the pH value, keeping the temperature, stirring the material, performing aeration treatment, performing press filtration on the substances in an aeration tank to obtain a press filtrate, performing steps of standing and centrifugation, mixing the material with aluminium ash and fluorite, heating the material and keeping the temperature for standby, filtering the material by a filter material, and discharging the waste water to obtain the ceramic production waste water. The method can effectively solve the problems of high operation cost and poor processing effect of the traditional ceramic production waste water processing methods. The ceramic production waste water processing method does not influence on the acid-base value and water temperature of the ceramic waste water, active silica gel is not required during usage, the produced sludge is easily processed, and the method has good processing effect for ceramic production waste water.

Description

technical field [0001] The invention belongs to the technical field of waste water treatment, and in particular relates to a treatment method for ceramic production waste water. Background technique [0002] The ceramic industry is a high-energy-consuming industry. The high energy consumption of ceramics will inevitably lead to high pollution. The ceramic industry has caused great pollution to the environment, especially in the porcelain area and surrounding areas where ceramics are developing rapidly. Judging from the current situation of the ceramic industry, most enterprises are distributed in the suburbs of large, medium and small cities, with many pollution points and a wide area, and most enterprises have backward production technology. The production equipment is obsolete and the pollution is serious. The total discharge of pollutants in the ceramic industry is relatively large, and the consumption of raw and auxiliary materials and energy in the ceramic industry is ...
