Embodiment 1
[0019] A sewage filter for absorbing water-soluble gas, the main body of which is a steel filter, the steel filter is filled with formaldehyde adsorbent in the production process, and the formaldehyde adsorbent consists of the following parts by weight Raw materials: calcium carbonate fiber 8-15, tetrabutyl titanate 20-40, silica sol 3-5, calcium aluminate 6-8, volcanic rock 60-80, PA6 nylon powder 6-9, gelatin 3-4, Ammonium bicarbonate 1-3, green dill slag powder 10-15, coal-fired slag 5-8, deionized water amount.
[0020] Described formaldehyde adsorbent is made by following specific steps:
[0021] S1. Mix tetrabutyl titanate with 3-4 times the amount of absolute ethanol, stir magnetically for 1 hour, chop the calcium carbonate fiber and add it to the above solution, continue magnetic stirring for 2 hours, slowly add deionized water dropwise, wait After forming the gel, continue to stir for 0.5-1 hour, then add it to an oven for drying and grinding at 80°C for subsequent u...
