S2: mixed-powder and waterglass are mixed, and being added and accounting for the partial size of mixed-powder weight 0.5~1% is 10~20 μm of wood powders,
Continue to mix, pelletizing is placed in tube furnace, pre- logical nitrogen, is that 0~20 DEG C/min is rapidly heated to preset temperature by heating rate
1~2h of high-temperature roasting at 1000~1200 DEG C, it is cooling to take out, it is subsequently placed in reduction furnace, is passed through 3NL/ at 700~800 DEG C
The H of min2It is restored through 1~2h iron-based to get silicon carbide compound.
10. a kind of method for preparing dyeing waste water adsorption treatment agent described in claim 1, which is characterized in that including following step
It is rapid: by biological base adsorbent, silicon carbide compound is iron-based and haydite by corresponding weight mix to get.
