技术简要说明目前,膨润土在水处理应用研究多采用粉末状吸附剂处理废水,粉状吸附材料粒度细,遇水后易分散粉化,造成后续固液分离十分困难,易形成新的工业污泥,这种因重金属离子的富集形成的二次污泥对环境的危害性更大。本项目针对粉末状膨润土或改性膨润土作为吸附剂在水溶液中使用后,很难与处理料液分离和回收再利用问题,以膨润土为主体,丙烯酰胺、丙烯酸为聚合单体,分别采用水溶液和乳液聚合的方法,合成了一系列深度脱除水中无机重金属离子及有机物的复合膨润土吸附剂,该吸附剂吸附性能高、成本低、易再生、便于工业实际使用。 市场前景与效益分析: 废水处理和饮用深度净化用吸附剂目前大多使用活性炭,本项目产品具有成本低和原料来源丰富的优势,经济效益显著,可替代活性炭使用,具有广阔的应用前景。产品成本3500元/吨,售价按活性炭价格5000元/吨计,年产5000吨复合膨润土吸附剂企业的年利润:5000*(5000-3500)=7500000元。

Technical Brief DescriptionCurrenly, powdered bentonite adsorbent is mostly used to treat wastewater in the applid research of water treatment. The powdered adsorbent is of fine granularity, and is easy to disperse and pulverize in water, which makes it very difficult to conduct the subsequent solid-liquid separation and easy to form new industrial sludge (this secondary sludge formed due to the enrichment of heavy metal ions is more harmful to the environment). Aiming at the difficulty to separate and recycle powdered bentonite or modified bentonite from the treated material after being used as adsorbent in aqueous solution, this project takes bentonite as the main object and acrylamide and acrylic acid as the polymerization monomers, and synthesizes a range of composite bentonite adsorbents that can remove inorganic heavy metal ions and organics in water through aqueous solution and lotion polymerization. Analysis of market prospect and benefit: activated carbon is mostly used as adsorbent for wastewater treatment and drinking water purification. The product of this project is characterized by low cost, abundant raw materials, and significant economic benefits. It can be used to replace activated carbon, and have a broad application prospect. The product cost is 3,500 yuan/ton, and selling price is 5,000 yuan/ton , the same as the price of activated carbon. The annual profit of an enterprise with an annual output of 5,000 tons of composite bentonite adsorbent: 5000 * (5000-3500) = 7,500,000 yuan.
