Problems solved by technology

Traditionally used detergents include bleaching powder, bleaching essence, copper sulfate, bromogeramine, etc., but most of these detergents are strong acids, strong alkalis and other components, which are highly corrosive, volatile, difficult to operate, and time-consuming. It will adversely affect the physical and mental health of the operators, and the cleaning effect is poor, the cleaning time is long, and the cleaning efficiency is low, which ultimately affects the production operation

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...
