摘要
Abstract
By investigating the regeneration capacity of clinoptilolite with ammonium-saturated, biological regeneration of clinoptilolite with different concentration of sludge and sodium ion was discussed. Result showes, increasing the activated sludge concentration and adding proper sodium ion can help speeding the regeneration rate of clinoptilolite with ammonium-saturated in a certain range. The regeneration time can be decreased to 2.3 h when increasing MLVSS to 2750 mg/L. But the regeneration rate is lower if continuing increasing the activated sludge concentration and sodium ion concentration. By relativity analysising the experiment results, it is found that desorption rate of ammonium in clinoptilolite is the limiting step of the ammonium-saturated clinoptilolite biological regeneration at high activated sludge concentration.关键词
