Firstly comparison the alternative the four adsorption material of adsorption performance, as well as the analysis of the adsorption material impact factors. And then for the the original adsorbent material adsorption properties of the the modified adsorbent material and regeneration test. Final flow dynamics simulation experiments and model analysis, so that the actual incidents of high-risk pollutants occurs in adsorption technology can be applied easily and effectively. Contrast, the adsorption capacity of the activated carbon of the comparison results of approximately 20 ~ 28mg / g, the adsorption capacity of the artificial zeolite in the adsorbent material choice test, the to four alternatives adsorption materials: carbon, synthetic zeolite, kaolin, Tourmaline adsorption isotherm approximately 18 to 25mg / g, and the adsorption capacity of the kaolin clay of about 15 to 28mg / g, the adsorption capacity of the electric powder of from about 0 to 25mg / g. Four kinds of materials, the adsorption capacity of the activated carbon is obviously the highest. To study the impact of the activated carbon adsorption capacity factors, the results show that the temperature, pH value of wastewater impact on the adsorption capacity of the activated carbon. The temperature increases, the adsorption capacity of the activated carbon decreases; wastewater pH around 7, reaches a maximum of about 28mg / g, the wastewater acidic or alkaline activated carbon adsorption capacity have led to the activated carbon adsorption capacity reduced. The the adsorption material modification trial, the use of different concentrations of ammonia, activated carbon impregnated with different time finalized: The most obvious effect of 15% ammonia on activated carbon impregnated 48h, activated carbon adsorption capacity increased by 56.4% to enhance Comparison, ethanol regeneration test, and ethanol as a regenerating agent and water as the regenerating agent as a regenerating agent, the activated carbon of the first regeneration, the regeneration rate reached 87.3%, even after activated carbon regeneration repeatedly put into use and repeated regeneration, the first after three regeneration can be achieved and the regeneration rate of 60.7%, and water as the regenerating agent is only 54.3% of the first regeneration rate, a lot worse than ethanol regeneration effect. The pH value of the same impact regeneration effect, under alkaline conditions, the effect of activated carbon regeneration is significantly higher than under neutral conditions to improve the regeneration effect of the acidic conditions decreased. The high risk pollutants blocking integration technology, for high-risk pollutants emergencies, the use of the most effective means for timely processing, the harm caused to minimize pollution. Dam model test using activated carbon adsorption, for the dynamic test of the flow, and finally the different dam system, the comparison result as follows: three dam system in the adsorption effect of initial adsorption Preferably, the removal rate of wastewater total phenols can reach 76% lasting performance, but the adsorption poor the adsorption 24h occurred penetration; the five dam system in the short-term adsorption adsorption rate was only 66%, but the sustained effect adsorption 48h after its removal rate of total phenolic wastewater there are still 20.1%. Finally, the integration of these various types of testing proposed emergency treatment of high-risk pollutants model, the model can be easily obtained corresponds to the amount of activated carbon required under field conditions to ensure compliance.
