【摘要】 近年来,随着生活水平的不断提高和工业生产的迅猛发展,无论是国内还是在国外,城市污水处理厂的规模和数量都迅速增长,水处理过程中所产生的污泥量在不断的增长,相应的污泥处理量也不断增大。同时,水体富营养化问题是环境保护面临的重大难题之一,而相对于氮而言,磷是水体尤其是淡水湖泊富营养化的营养控制因子,尽可能地减少排入水体中的磷含量是急待解决的环境问题。基于解决上述两个重大问题,通过污水污泥吸附剂去除磷,不但解决了污水厂污泥去向,而且可以有效地去除水中的磷。本文研究了污水污泥吸附剂除磷及其效能研究与应用。实验以果壳活性炭做参比活性炭,经过酸溶振荡、吸附振荡、离心等过程对磷(磷酸二氢钾,三聚磷酸钠,甘油磷酸钠)的去除效果进行了考察。首先,通过单个影响因子的实验,确定最佳的吸附时间、投加量、pH范围、初始磷浓度、振荡速度等。再此重点对吸附动力学和吸附等温线做了详细阐述。从而给人们提供选择反应的条件,掌握控制反应进行的主动权,同时,了解反应历程还有助于了解有关吸附机理;了解吸附剂对吸附质的吸附能力。接着,本文考察了在有腐植酸,蛋白质,多糖,Cr6+,硫酸根,碳酸根,硝酸根,碳酸氢根等存在时,它们对三种磷去除的影响。同时,也进行了四种吸附剂对实际污水进行了磷去除实验。最后,进行了磷解吸实验。重点采用了酸解吸。同时进行了吸附剂的再生。总之, C吸附剂在效果最好,而果壳活性炭次之;而A吸附剂和B吸附剂几乎在各个实验中均表现不出明显的效果。更多还原

【Abstract】 In recent years, with the continuous improvement of living standards and the rapid development of industrial production, whether it is domestic or in foreign countries, the size and number of urban sewage treatment plant have a rapid growth and the sludge of treatment process in the volume also grow rapidly, the corresponding amount of sludge treatment continued to grow. At the same time, the problem of eutrophication is a major environmental problem facing one of the terms.In relation to nitrogen, phosphorus is a controlling factor in a body of water that , especially freshwater lake eutrophication ; reducing the phosphorus content of the water as much as possible is a urgent environmental issues to be resolved. Based on these two major issues to resolve, through the sewage sludge adsorbing phosphorus, not only it solved the whereabouts of sewage sludge and water can effectively remove phosphorus.In this paper, I researched on sewage sludge adsorbing phosphorus and its application performance. Using activated carbon as a comparative adsorbent, after acid-soluble oscillation, adsorption oscillation, centrifugal process, we abserve the phenomenon that sludge-derived adsorbent adsorb phosphorus (potassium dihydrogen phosphate, sodium tripolyphosphate, sodium glycerol) .First of all, do the impact of the adoption of a single factor experiments to determine the optimal adsorption time, dosage, pH range, the initial phosphorus concentration, the speed of oscillation and so on. This re-focus on the adsorption kinetics and adsorption isotherm described in detail. Therefore it provides more choices to the people of the conditions of reaction, reaction in control of the initiative, at the same time to understand the reaction mechanism also helps to understand the adsorption mechanism; understanding of adsorbate adsorbent adsorption capacity.Then, this paper investigated the impact on three types of phosphorus removal in the existence of humic acid, protein, amylase , Cr6 +, sulfate, carbonate, nitrate, bicarbonate. At the same time, four types of adsorbents have also been carried out on the actual wastewater phosphorus removal experiment.Finally, I made the phosphorus-desorption experiments. They are focused on the use of the acid desorption. At the same time, a adsorbent regeneration has been made.All in all,C in the best adsorbent, followed by activated carbon; and A and B adsorbent adsorbent in almost all experiments have shown no significant results.更多还原
