Abstract

The invention discloses heavy metal sewage treatment particles and a preparation method thereof. The heavy metal sewage treatment particles are prepared from the following materials in parts by weight: 11-23 parts of activated carbon, 8-16 parts of chitosan, 14-26 parts of epoxy resin, 10-18 parts of meerschaum, 7-13 parts of smectite, 9-15 parts of alginic acid, 6-14 parts of gelatin, 15-25 parts of alum, 5-10 parts of barium sulfide, 8-14 parts of calcium carbonate, 11-16 parts of cellulose, 4-8 parts of nano titanium dioxide, 6-14 parts of hydrotalcite, 13-19 parts of silica gel and 9-19 parts of sodium sulfhydrate. The heavy metal sewage treatment particles can quickly precipitate heavy metals, and can sterilize and clean the water source.

Description

technical field [0001] The invention specifically relates to a heavy metal sewage treatment particle and a preparation method thereof. Background technique [0002] Sewage treatment plants are the main functional undertakers of water environmental pollution control and play a key role in purifying water pollution. By the end of 2014, nearly 4,000 urban sewage treatment facilities had been put into operation across the country, with a total designed treatment capacity of more than 50 billion m3 / d. A prominent feature of the sewage treatment plant is that there are many types of pools and large areas: regulating tanks, acidification hydrolysis tanks, primary sedimentation tanks, aerated grit chambers, biochemical tanks, secondary sedimentation tanks, high-density sedimentation tanks, sand filters, ultraviolet disinfection pool etc. During the production process, due to the complex composition of pollutants and the interaction of metal ions, inorganic components, organic matt...
