Embodiment Construction

[0033] When the present invention is implemented, as figure 1 and figure 2 As shown, the specific steps are as follows:

[0034] First, take 1 mm of bentonite and pour it into the turntable machine, control the humidity at 75% through the nozzle, control the speed at 20 rpm, and form the turntable for 15 minutes to obtain the carrier 1.

[0035] Then, add 100 nanometers of activated nano-tourmaline powder, control the humidity to 75%, rotate at 50 rpm, run for 15 minutes, complete the innermost coating 2, and sinter at 600°C for 4 hours.

[0036] Then, put it back into the turntable, control the humidity to 70%, rotate at a speed of 50 rpm, replace the coating material with 300nm hydroxyapatite, run for 15 minutes, complete the middle layer coating 3, and sinter at 400°C for 3 hours.

[0037] Finally, the coating material is replaced with activated carbon powder of 1 micron, the rotating speed is 50 rpm, and the humidity is controlled at 70%. After running for 20 minutes, t...

Abstract

The invention discloses a multiple-effect biological solid catalyst used for reclaimed water treatment, consisting of three layers of coatings; the innermost layer is an activated nanometer tourmalinematerial, the middle layer is hydroxylapatite, the outer layer is active carbon powder and the three layers of coating of the solid catalyst form gradient porous channels from nanometer level to micron level from inside to outside. A preparation method thereof comprises the following steps of: controlling humidity and rotating speed, and molding the selected bentonite by adopting a rotary method;injecting the activated tourmaline powders into a rotary table, regulating humidity and rotating speed, then finishing the innermost layer coating after operation and calcining; exchanging the coating materials into hydroxylapatite, regulating and controlling humidity and rotating speed, finishing the middle layer coating after operation and calcining; exchanging the coating materials into activecarbon powder, regulating and controlling humidity and rotating speed, finishing the outer layer coating after operation and drying and obtaining the finished product of the solid catalyst. The multiple-effect biological solid catalyst can improve the traditional biochemical efficiency by 20 to 30 percent and reduce the foul odour (taking hydrogen sulfide as index) by 50 to 60 percent.

Description

technical field [0001] The invention belongs to the novel biological filler technology in the technical field of reclaimed water treatment, and in particular relates to a biological solid catalyst with multiple functions and a preparation method thereof. Background technique [0002] Biotechnology is the key technology to solve China's water environment problems. The sewage treatment rate in developed countries has reached more than 85%, and treatment plants are quite popular. Therefore, the hot topic of sewage treatment research today is sludge treatment, and the research and development of sewage treatment technology that does not produce sludge from the source. China's sewage treatment has just started, and most of the technologies used are old-fashioned activated sludge method, but the average treatment rate is less than 15%, which is far lower than that of developed countries. Therefore, in the face of China's huge environmental market, when developing wastewater treat...
