Embodiment Construction

[0015] First select 20-30g of carbon black with a particle size of 50-80nm, roll and granulate in a low-speed drum, control the rolling speed to 60r / s, and the heating temperature to 70-80°C. At the same time, during the rolling process, every 3 Spray 10mL deionized water and 10g carbon black powder for ~5s to bond and roll granulation. The granulation time is 5-10min. Dry at a temperature of 80-90°C to ensure that the water content of the carbon black is 40-45%, and then take it out; then take 300g of marble particles and roll them in a high-pressure rolling device to form super carbon black with a particle size of 20-30nm. Fine calcium carbonate particles, and evenly sprinkle it into 100mL polydimethylsiloxane solution, mix and stir evenly, pass the rotating machine, and spray the mixed polydimethylsiloxane evenly at a temperature of 70-80°C Solution, spray this airflow to ensure that the calcium carbonate powder is evenly covered on the carbon black particles; wash the ca...

Abstract

The invention relates to a preparation method of microparticles for removing organic chlorine residue in a drinking water source and belongs to the field of environmental protection. The preparation method comprises carrying out rolling granulation on carbon black by a low speed roller, wherein in rolling granulation, deionized water and carbon black powder are sprinkled to the carbon black so that the materials are bonded and are rolled to form particles, after rolling granulation, taking out the carbon black particles with different sizes, carrying out dispersion, carrying out drying, taking out the particles, grinding marble particles to obtain ultrafine calcium carbonate particles, uniformly scattering the ultrafine calcium carbonate particles into a polydimethylsiloxane solution, carrying out mixing stirring to obtain a uniform mixture, then uniformly sprinkling the mixed polydimethylsiloxane solution by a rotation machine, carrying out air-flow injection, carrying out washing by hydrochloric acid, carrying out flushing and carrying out drying to obtain the microparticles for removing organic chlorine residue in a drinking water source. The microparticles have chlorine residue removal efficiency of 99% or more, have high treatment effects, have short treatment time, do not occupy a large area of land, have simple treatment processes and have a high cost.

Description

technical field [0001] The invention relates to a preparation method for removing organic residual chlorine microparticles in drinking water sources, and belongs to the field of environmental protection. Background technique [0002] Residual chlorine refers to the effective chlorine remaining in the water after the water has been chlorinated and disinfected for a certain period of time. Disinfectants should be added to the tap water during the water purification process to inactivate pathogenic microorganisms in the water. Due to the high cost performance of chlorine gas, it is widely used in the domestic water treatment industry. If the concentration of residual chlorine in tap water is too high, the main hazards are: strong irritation and damage to the respiratory system. It is easy to react with organic matter in water to generate carcinogens such as chloroform. It can cause damage to skin cells and intercellular matrix, which can easily cause dry skin, chapped, pimple...
