Nowadays, environmental protection has become a global concern, and countries all over the world, especially some developed regions, pay much attention to the prevention of environmental pollution. Therefore, in the case of people's awareness of environmental protection is gradually strengthened, the discharge of wastewater and recycled water quality requirements are also increasingly high.
1. For the purification of sewage, the use of coconut shell activated carbon adsorption of organic matter in water, color, odor and deodorization. Color, deodorization and deodorization. Because the depth purification method of coconut shell activated carbon can effectively improve the water quality, domestic and foreign in the new water plant basically use this method.
2. In the organic industrial wastewater treatment, due to the coconut shell activated carbon on the water of organic substances such as cod has outstanding removal ability. For some difficult to be degraded organic matter has a unique removal effect, which is used in tannery wastewater treatment, paper dye chemical wastewater treatment, coking wastewater treatment and other organic wastewater treatment.
3. Inorganic industrial wastewater treatment, some adsorption activated carbon has certain selective adsorption function for inorganic heavy metal ions in wastewater. For example, the adsorption and removal rate of granular activated carbon for plasma can reach more than 86%, and it has good adsorption effect on other metal ions such as mercury, lead and iron. In addition, the adsorption effect of coconut shell activated carbon on cl2.br2.i2 in water is also very strong.
On the basis of the continuous progress of water treatment technology, countries around the world are studying the use of coconut shell activated carbon for water treatment in cooperation with other methods. In order to improve the quality of water, the combined method of treatment is more effective, filling the phenomenon of high wastewater treatment costs due to the frequent use of regeneration of coconut shell activated carbon. Its solution has the following ways:
Powdered activated carbon treatment: it is in the absorption as well as microbial oxidation and decomposition of the joint cooperation to remove pollutants. The porous coconut shell activated carbon absorbs the organic matter and oxygen in the wastewater, supplying high-quality nutrient source for microorganisms to grow and reproduce, and the microorganisms produce colloidal substances in the process of growth, which are absorbed and collected in the fine pores of coconut shell activated carbon. In addition, the biological and organic matter on the charcoal contact time is relatively long, so that the original difficult to degrade organic matter will also be decomposed.
Coconut shell activated carbon treatment method: it is the ozone oxidation, coconut shell activated carbon will be a combination of the two methods, but also easier to let the coconut shell activated carbon adsorption, for the dyes of the wastewater of the killing, deodorization, and decolorization ability is significant and extends the coconut shell activated carbon use time.
Coconut shell activated carbon adsorption method: This method is to use coconut shell activated carbon for organic compounds collection effect and selective adsorption of dissolved oxygen in water. When the temperature and nutrition are suitable, microorganisms will grow on the surface layer of coconut shell activated carbon, so that the adsorption function of coconut shell activated carbon can cooperate with the oxidative decomposition of microorganisms. In this way, not only can improve the efficiency of wastewater treatment, but also can make the use of coconut shell activated carbon time to extend a lot, but also reduces the cost, easy to run the implementation of management, which is a newly developed sewage treatment technology.
