Embodiment 1
[0011] Embodiment 1. (1) After the pottery clay is measured and proportioned, it is loaded into a ball mill and ground for 8 hours (the material of the grinding ball is an alumina composite ball, and the size ratio is φ25: φ35: φ45=35: 40: 40), and the ground Spread the clay evenly in the enamel plate, add 8% binder to the solution, stir evenly, and dry it in a desiccator for 12 hours after granulation; (2) Put the granulated clay into the mold, and the mold is spherical After heating and forming, put the ceramsite into the muffle furnace, heat to 200°C, and keep it warm for 0.5 hours, then raise the temperature to 500°C at a speed of 60°C / h, keep it warm for 2 hours, and raise the temperature to 850-900°C at a speed of 40°C / h , after 2 hours of heat preservation, naturally cool down to room temperature and become macroporous ceramsite; (3) Take a certain amount of macroporous ceramsite, add 0.05mol / L HCl solution to make it completely soaked, wash away a large amount of acid s...
Embodiment 2
[0012] Embodiment 2. prepare and process ceramsite carrier as step (1)~(5) in embodiment 1, (6) add 10% gamma-epoxytriethoxysilane toluene solution of ceramsite weight 80%, in Shake overnight at room temperature; (7) Filter and wash thoroughly with acetone, transfer to a rotary evaporator, add 0.05mol / L HCl, soak at 50-60°C, react for 1-2h, wash with water until neutral, and finally wash with acetone Air-dried to obtain a kinetic ceramsite carrier; (8) in a glass column with a certain inner diameter and length, add a functionalized ceramsite carrier with a volume of 20-30% of the glass column, and add the activated sludge supernatant; (9) pass into the domestic waste water adjusted to pH=7-8 in advance and soak the carrier in the column, and add a total volume of 0.01% diamine cross-linking agent under the condition of stuffy exposure to carry out immobilization reaction for 24 hours; (10) every day from the next day Replace the waste water in 1 / 3 column and enter the stage of...
Embodiment 3
[0013] Embodiment 3. as step (1)~(5) in embodiment 1 prepares and handles ceramsite carrier, (6) adds the 10% gamma-aminopropyltriethoxysilane toluene solution of ceramsite weight 75%, in Shake overnight at room temperature; (7) Filter and wash thoroughly with acetone, transfer to a rotary evaporator, add 0.05mol / L HCl, soak at 50-60°C, react for 1-2h, wash with water until neutral, and finally wash with acetone Air-dried to obtain a kinetic ceramsite carrier; (8) in a glass column with a certain inner diameter and length, add a functional ceramsite carrier with a volume of 20-30% of the glass column, and add high-efficiency microbial flora B350; (9) pass through Adjust the domestic waste water of pH=7-8 in advance to immerse the carrier in the column, add a total volume of 0.01% diepoxy cross-linking agent under the condition of stuffy exposure to carry out immobilization reaction for 24 hours; (10) start every day from the second day Replace 1 / 3 of the waste water in the col...
