Description
技术领域 本发明涉及一种微波辐射纸浆漂白废液处理的方法，属于环境保护技术。Technical field The present invention relates to a method for treating pulp bleaching waste liquid by microwave radiation, which belongs to the environmental protection technology.
背景技术 纸浆漂白废液是高浓度的有机废水，基于高浓度木质素、氯酚等难降解物质的存在，使得纸浆漂白废液的处理极为困难。人们在纸浆漂白废液处理方面曾经做过许多工作，有化学混凝法、气浮法、曝气法、活性炭吸附法，以及等离子体技术、液膜分离技术、生物化学法和氧化法等，这些方法虽然都取得一定的效果，但是由于我国绝大多数造纸企业资金少、技术薄弱、管理水平较低，一般都无力建设和运转基建投资高、处理能耗大的废水处理厂，而现阶段的由于受到各方面因素的限制也难以普及。Background technology Pulp bleaching waste liquid is high-concentration organic wastewater. Due to the presence of high-concentration lignin, chlorophenol and other refractory substances, the treatment of pulp bleaching waste liquid is extremely difficult. People have done a lot of work on the treatment of pulp bleaching waste liquid, including chemical coagulation, air flotation, aeration, activated carbon adsorption, plasma technology, liquid membrane separation technology, biochemical method and oxidation method, etc. Although these methods have achieved certain results, due to the low capital, weak technology and low management level of most papermaking enterprises in my country, they are generally unable to build and operate wastewater treatment plants with high infrastructure investment and high energy consumption. Due to the limitation of various factors, it is also difficult to popularize.
发明内容 在微波辐射处理废水过程中，利用微波辐射，可以大大提高反应速率，加快净化进程。传统方法所需时间较长，利用微波辐射加热只需10-40分钟即可达到甚至超过传统方法所达到的结果。提高效率大大降低生产成本。因此可以说微波辐射环保技术的应用极具发展前途，它不仅仅可以在环保工业中得到广泛的应用，还可以在纺织、食品加工、化工等行业进行广泛的应用。Summary of the invention In the process of microwave radiation treatment of wastewater, the use of microwave radiation can greatly increase the reaction rate and speed up the purification process. The traditional method takes a long time, and it only takes 10-40 minutes to heat with microwave radiation to achieve or even exceed the result achieved by the traditional method. Improve efficiency and greatly reduce production costs. Therefore, it can be said that the application of microwave radiation environmental protection technology has great development prospects. It can be widely used not only in environmental protection industry, but also in textile, food processing, chemical industry and other industries.
所述净化时，微波功率可为100瓦～1000瓦。反应时间可为5秒～35分钟。During the purification, the microwave power may be 100 watts to 1000 watts. The reaction time may be 5 seconds to 35 minutes.
具体实施方式 实施例1取50mL的废水在微波辐射为800W，辐射30min，钢渣与活性炭总量13g，比例23∶1条件下，漂白废液的COD去除率能稳定达到90％以上。Specific implementation methods In Example 1, 50mL of waste water was irradiated by microwave at 800W for 30 minutes, the total amount of steel slag and activated carbon was 13g, and the ratio of 23:1, the COD removal rate of bleaching waste liquid can reach more than 90% stably.
