specific Embodiment approach 1

[0023] Embodiment 1: A kind of high-performance mesoporous activated carbon suitable for bioaugmentation in this embodiment has a mesopore volume of 0.45 cm 3 / g~0.65cm 3 / g of mesoporous activated carbon.

specific Embodiment approach 2

[0024] Embodiment 2: The difference between this embodiment and Embodiment 1 is that a kind of high-performance mesoporous activated carbon suitable for bioaugmentation has a mesopore volume of 0.58 cm 3 / g~0.65cm 3 / g of mesoporous activated carbon. Other steps and parameters are the same as those in Embodiment 1.

specific Embodiment approach 3

[0025] Specific embodiment three: the preparation method steps of a kind of high-performance mesoporous activated carbon suitable for bioaugmentation of this embodiment are as follows:

[0026] 1. After pulverizing anthracite, long-flame coal and coconut shell, pass through a 20-50 mesh sieve, and then mix the three evenly according to the mass ratio of anthracite, long-flame coal and coconut shell to (4-6):3:2 to obtain mixture, then the mixture is pulverized until more than 80% of the mixture passes through a 325 mesh sieve to obtain a mixture;

[0027] 2. Put the mixture obtained in step 1 in the dry molding equipment, and briquetting under the condition of pressure of 200MPa-250MPa. After briquetting, crush it into a block with an average diameter of 2mm-10mm, and then place it in the rotary carbonization In the furnace, under a nitrogen atmosphere, the temperature is raised from room temperature to 550-650°C at a rate of 10°C / min-20°C / min, and the temperature is kept for ...

Abstract

The invention discloses high-performance mesoporous active carbon suitable for biological enhancement and a preparation method thereof, relates to active carbon and a preparation method thereof, and in particular to high-performance mesoporous active carbon which is suitable for biological enhancement and is applied to water treatment ozone-biological active carbon and ozone-biological enhanced active carbon processes, and a preparation method of the high-performance mesoporous active carbon. The invention aims to solve the problems that the existing active carbon has low mesopore rate and low biological loading amount on the surface and in pore passages of the active carbon. The mesoporous volume of the high-performance mesoporous active carbon is 0.45cm<3> / g-0.65cm<3> / g. The preparation method comprises the following steps of: firstly respectively crushing and screening blind coals, candle coals and coconut shells which are used as precursors, and then matching in proportion; then, performing briquetting, carbonization, oxidization before activation, activation and modification after activation on the matched raw material; and finally, screening to obtain the mesoporous active carbon. The mesopore rate of the obtained mesoporous active carbon reaches 40-70%, and the biological loading amount can be improved to 106-107CFU / g, so that the high-performance mesoporous active carbon can be applied to the field of water treatment.

Description

technical field [0001] The invention relates to a preparation method of activated carbon, in particular to a preparation method of high-performance mesoporous activated carbon suitable for bioenhancement in water treatment ozone-biological activated carbon and ozone-biologically enhanced activated carbon processes. Background technique [0002] With the increasingly serious pollution of drinking water sources, ozone-biological activated carbon (O 3 -BAC) and ozone-biologically enhanced activated carbon (O 3 -BEAC) technology as the core of advanced drinking water treatment technology has been widely used, and has a high decontamination efficiency for natural organic matter, persistent organic pollutants and endocrine disruptors in water. In the long-term process of activated carbon water purification process, when the adsorption capacity of activated carbon filter material is close to saturation, O 3 -BAC and O 3 -The water purification efficiency of the BEAC process main...
