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...

Abstract
The invention discloses a sewage filter screen for adsorbing a gas soluble in water. A main body of the sewage filter screen is a steel filter screen; the steel filter screen is filled with a formaldehyde adsorbent in a production process; the formaldehyde adsorbent is prepared from the following raw materials in parts by weight: 8-15 parts of calcium carbonate fibers, 20-40 parts of tetrabutyl titanate, 3-5 parts of silica sol, 6-8 parts of calcium aluminate, 60-80 parts of volcanic, 6-9 parts of PA6 nylon powder, 3-4 parts of gelatin, 1-3 parts of ammonium bicarbonate, 10-15 parts of scindapsus aureus residue powder, 5-8 parts of coal slag and a defined amount of deionized water. The sewage filter screen for adsorbing the gas soluble in water provided by the invention is characterized in that the main body is the steel filter screen, the steel filter screen is filled with the formaldehyde adsorbent in the production process and the formaldehyde adsorbent has ultrahigh adsorption capacity and adsorption speed.
Description
technical field [0001] The invention relates to a filter net, in particular to a sewage filter net for absorbing gas easily soluble in water. Background technique [0002] With my country's industrial progress and social development, water pollution has become increasingly serious and has become a difficult problem in environmental governance. According to monitoring by the environmental department, at least 100 million tons of untreated sewage is discharged directly into water bodies every day in cities and towns across the country. The water quality of more than half of the country's seven major water systems is polluted, 1 / 3 of the country's water bodies are not suitable for fish, 1 / 4 of the water bodies are not suitable for irrigation, 90% of urban waters are seriously polluted, and 50% of urban water sources are not suitable for drinking water standard. These statistics continue to grow as the economy continues to grow. [0003] Water pollution is mainly caused by po...
