Analysis of Desmutting Ability of Molecular Sieve and Activated Alumina Ball

The usefulness of molecular sieves is great. It can not only be used as a desiccant, but also can be used as a purifying agent. It can be used to clearly distinguish impurities in water.

1. The discharge of wastewater is large and the water environment is overwhelmed. The total amount of surface water resources in the country is about 2,800 billion cubic meters. In 2003, the total discharge of sewage was nearly 46 billion tons, and the discharge of COD (chemical oxygen demand) reached 13.336 million tons. In particular, in the northern provinces where the water shortage is relatively severe, the discharge of sewage wastewater accounts for a maximum of 38.9% of the total surface water resources. If the province's surface water is diluted, the COD concentration is 6 provinces super III water, and 3 of them. Provincial Super V water.

2. Wastewater discharge regulations are not strict. China's current wastewater discharge regulations are relatively loose, and the limits are much higher than the “surface water environmental quality specifications”. For example, the 11 primary pollution factors in the “Sewage Induction Emission Regulations”, the emission standard limits are 2.5- of the V-type surface water specifications. 50 times, the occupational wastewater discharge standard is higher, and the papermaking wastewater discharge specification is 11.25 times of the V-type surface water specification.

3. The phenomenon of excessive emissions and smuggling of enterprises is severe. According to statistics, in 2003, nearly 9% of industrial wastewater was discharged in Henan Province, and the domestic sewage treatment rate was still 35%. From this budget, 40% of the total discharged sewage was over-discharged. Curbing excessive emissions and smuggling is an urgent problem to be solved.

Activated alumina spheres not only perform fluoride removal well, but also high-quality defluorination of groundwater. We all know that fluorine is a harmful substance to human body. Long-term use can cause human poisoning to die. Groundwater in most parts of China contains harmful substances such as “fluorine”, so we must use high-tech skills to carry it out. Fluoride disinfection. The activated alumina ball is a good fluorine removal product, and it can be used to defluorinate the groundwater with some skill.

The principle of removing the fluorine from the activated alumina sphere: the activated alumina sphere is similar to the anion exchange resin except for the fluoride, but the selective anion resin for the fluoride ion is large. The activated alumina ball has good desorption and desorption, and the capacity is stable. The activated alumina ball per cubic meter absorbs 6400 grams of fluorine. This product has high strength, low wear, no softening of water immersion, no swelling, no powdering, no cracking. Can be widely used in petroleum cracking gas, ethylene propylene gas deep boring and hydrogen production, air separation equipment, surface drying machine boring, fluoride treatment in hydrogen peroxide can also remove sulfur, hydrogen, sulfur dioxide, hydrogen fluoride, hydrocarbons, etc. Contaminants, especially customary fluorine-containing water defluoridation treatment.
