[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...
