摘要
磷的任意排放引起水体富营养化造成了水体污染,减少磷排放已经引起了社会的关注。粘土矿物资源丰富,具有特殊的结构组成,对磷的去除有着良好的效果,特别是改性的粘土矿物。因此,系统总结粘土矿物对磷的去除效果与机理,为更好的开发粘土矿物在废水处理的应用奠定基础。
Abstract
Water pollution characterized eutrophician was caused by waste containing phosphorus,so phosphorus reduced should paid attention.To the clay minerals with special structure are abundant in nature,they play an important role in removing the phosphorus out of waster,especically the modified.The effect and mechanism of phosphorus removed was summarized,in order to set good foundation for exploring clay minerals better in waste water treatment.

The project is subsidized by Natural Science Fund of Yunnan province. (No.2000B0023M.)In order to remove the phosphorus that causes aquatic eutrophication, a new dephosphorates absorbent was invented to reduce the exhaust of phosphorates and an effective method of advanced wastewater treatment was provided .The main content is described as follows:(1) By means of addition of rare earth oxide to the carrier zeolite(4A) and roasting it in high temperature, the new dephosphorates absorbent was prod...
摘要
研究了粉末活性炭(PAC)和颗粒活性炭(GAC)对光合细菌(PSB)去除废水中氨氮和磷的影响,同时研究了粉末活性炭投加量对氮磷去除效率的影响。结果发现,活性碳对废水中氮磷的去除有显著的影响,粉末活性炭固定光合细菌的去除效果较好,其对NH4+-N和PO43--P的去除率分别达92.5%和78.8%;投加活性炭后,光合细菌生长更快,同时粉末活性炭投加量也影响对氮磷的去除效率。

摘要
研究几种天然矿物和冶金炉渣对生活污水的除磷效果。结果表明，混合物料用于生活污水除磷的效果极佳，在初期排放水的含磷浓度远远低于国家废水排放标准，但随着处理水量的增加，除磷效果变差，钢渣中含有的大量碱性物质CaO，使出水pH很高，较高的pH与较好的除磷效果相关。
Abstract
Removal of nitrogen and phosphorus in wastewater using photosynthetic bacteria(PSB) immobilized on both powered activated carbon(PAC) and granular activated carbon(GAC) was studied in the present investigation.The influence of PAC dosage on treatment effects was also discussed.The results showed that PAC+PSB could remove nitrogen and phosphorus more effectively with removal rates of NH4+-N and PO43——P,respectively,of 92.5% and 78.8%.In addition,it was discovered that PSB grew faster with AC in o...
Abstract
A sample of the clean and sieved(200 mesh)copper mine tailings was characterized by XRD;its major constituents were:Fe2O3(31.0%),SO3(27.4%),CaO(17.7%),SiO2(16.9%),Al2O3(4.20%).The sample was thermally activated to produce a more effective adsorbent for removing phosphate from solutions in the lab.The best adsorbent was produced by heating at500℃for 2 h.The adsorption isotherm data were well represented by both the Langmuir and the Freundlich isotherm models.Given the maximum adsorption capaci...

摘要
本项目为云南省自然科学基金资助项目，项目编号为2000B0023M。本文针对造成水体富营养化的磷，采用吸附法进行处理，开发新型高效脱磷吸附剂，以达到工业废水及生活污水中磷的零排放，为废水的深度除磷提供一条切实可行的途径。文中主要研究内容为：(1)将稀土氧化物加载在载体沸石(4A)上，通过高温焙烧等方法制备成高效脱磷吸附剂，并从理论上探讨了稀土吸附剂的脱磷机理；(2)研究了制备工艺及制备条件对稀土吸附剂脱磷性能的影响及对载体化学组成和物理结构的影响；(3)考察了浸渍液浓度、溶液pH值、浸渍时间、焙烧温度、焙烧时间对脱磷率及吸附量的影响，并用正交试验法提出了稀土吸附剂的最佳制备条件；(4)采用X衍射、透射电镜、扫描电镜等分析手段观察化学处理及热处理对载体的影响；(5)对研制的稀土吸附剂进行了适宜的脱磷条件实验和解吸实验，测定了吸附等温线和穿透曲线，提出了吸附模型，并对脱磷机理进行了探讨；(6)用吸附剂对磷肥厂的实际水样和生活污水水样进行了处理，并对吸附剂去除氨氮、氟离子、砷离子(Ⅲ)进行了初步研究。研究结果表明：稀土吸附剂的最佳制备条件是镧离子浓度为0.35％的溶液...
