Description

废水处理用的复合净水剂 Wastewater treatment of composite Purifying Agent

本发明涉及一种废水处理用的复合净水剂水是人类生活和生产活动中不可缺少的物质资源,近二十年来,随着经济的发展,环境污染已越来越明显。 The present invention relates to a composite water purifying agent wastewater treatment with human life and production activities is an indispensable material resources, the last two decades, with economic development, environmental pollution has become increasingly evident. 通过净水剂与水中的污染物反应是净化水质的一种有效而快捷的方法,全世界普遍用此方法作为净化水质的重要途径之一。 The method of purifying agent by the pollutants react with water in a water purification effective and efficient, universally used this method as one of the important ways to purify water quality. 日本、欧美在此方面投入大量资源,研制出各种类型的净水剂。 Japan, Europe and the United States put a lot of resources in this regard, the development of various types of water purification agent. 近年来继聚合氯化铝之后,还研制了聚合铝盐混合物。 In recent years, following the PAC, it has also developed a polymeric aluminum salt mixture. 但由于价格偏高,尚难在我国推广。 However, due to high prices, it is difficult to promote in our country. 国内目前研制和应用的多为单一型的净水剂,只能选择性的去除污染物,适应性较窄。 China is currently the development and application mostly single type of water purification agent, only selective removal of contaminants, adaptability narrow. 在环境污染日益严峻的今天,研制性能良好,效率高的净水剂就显得尤为重要。 In today's increasingly Yan Jun environmental pollution, the development of good performance, high efficiency water purification agent is particularly important. 在环境污染日益严峻的今天,研制性能良好,效率高的净水剂就显得尤为重要。 In today's increasingly Yan Jun environmental pollution, the development of good performance, high efficiency water purification agent is particularly important.

本发明的目的是提供一种高效、低成本、特别能够去除废水中惰性污染物的复合净水剂。 Object of the present invention is to provide an efficient, low cost, in particular is capable of removing inert contaminants in wastewater purifying agent complex.

本发明的技术方案是:废水处理用的复合净水剂含有可溶性单体,占总重量的60~95%,和不可溶性单体,占总重量的40~5%,其有效氧化铝(Al2O3)的含量必须≥15%。 Aspect of the present invention is: with the compound Purifying wastewater containing soluble monomers, 60 to 95% by weight of the total, and insoluble monomers, from 40 to 5% by weight of the total, effective alumina (Al2O3 ) content must be ≥15%.

可溶性单体选自硫酸铝、氯化铝、氯化铁、碱式氯化铝、聚合铝中的一种或几种。 Soluble monomer is selected from aluminum sulfate, aluminum chloride, iron chloride, basic aluminum chloride, polyaluminum one or several.

不可溶性单体选取自高岭土、膨润土、硅藻土、石英粉、沸石、明矾石中的一种或几种。 Insoluble monomer selected from kaolin, one or more of bentonite, diatomaceous earth, Shi Ying powder, zeolite, of alunite.

不可溶单体最好先经粉磨、颗粒半径值控制在R≤0.03毫米,并经膨化或酸化处理。 Insoluble monomers preferably are ground to a value, control R≤0.03 mm particle radius, and by expanding or acidification.

各种废水都是以水为分散介质的分散体系。 They are various waste water as the dispersion medium of the dispersion system. 胶体颗粒能保持稳定主要有两个原因:首先,由于同类的胶体微粒电性相同,它们之间的静电斥力阻止微粒间彼此接近而聚合成较大的颗粒;其次,带电荷的胶粒和离子都能与周围的水分子发生水化作用,形成一层水化壳,也阻碍各胶粒的聚合。 Colloidal particles that remain stable for two main reasons: Firstly, the same as the colloid particles are electrically similar, the electrostatic repulsion between them close to each other to prevent inter-particle aggregate into larger particles; secondly, charged ionic micelles and hydration can occur with surrounding water molecules, form a hydration shell, but also inhibit the polymerization of each micelle. 胶粒带电越多,ε电位就越大,稳定性越强。 The more charged micelles, [epsilon], the greater the potential, the stronger the stability. 水质处理就是通过投加化学药剂来破坏胶体的稳定性,使其沉淀,达到净化的目的。 Water treatment is to destroy the chemical stability by adding colloidal, precipitated, to achieve the purpose of purification. 按反应机理,可分为压缩双电层、吸附电中和、吸附架桥、沉淀物网捕四种。 According to the reaction mechanism, the compression can be divided into the electric double layer, and the electrical adsorption, adsorption bridging precipitate netting four. 本发明选用的可溶性单体具有引发连锁脱稳反应的作用,控制不溶性单体颗粒半径可以改善生成絮体的密度和强度,增大不溶性单体的接触面积可以增强其吸附架桥能力,这些因素都大大提高了净化水质的效率。 The present invention is selected having monomer soluble initiator effect destabilization chain reaction, controlling the particle radius insoluble monomer can improve the density and strength of the floc, the contact area insoluble monomer can enhance its adsorption bridging capability, these factors We have greatly improved the efficiency of water purification.

复合净水剂在通过化学反应来破坏废水中的污染物的稳定性的同时,增加其吸附架桥能力及改善生成絮体的粒径、密度和强度,比单一型净水剂具有更多的功效。 While purifying agent complex destabilize wastewater contaminants by chemical reaction, increase the adsorption capacity and bridging improved particle size, density and strength of the resultant floc, having more than a single type Purifying Agent effect.

本发明与单一型铝盐相比具有下列优点和积极效果:应用范围广,对多种废水都可以达到较好的混凝效果;快速形成矾体,沉淀性能好,脱色效果好;适宜的PH值及温度范围较宽;单位使用量比单一型为低。 The present invention as compared to a single type of aluminum has the following advantages and positive effects: a wide range of applications, a variety of waste water can achieve good coagulation; alumina body formed quickly, good settling properties, good bleaching effect; suitable PH value and the wide temperature range; units using a single type is a low ratio. 四个方面充分发挥作用。 Four full effect. 从而具有更高的净化效率。 Thus has a higher purification efficiency. 而且原材料易得,价格便宜。 And raw materials readily available and cheap.

通过上述方法制成的复合净水剂,应用于畜牧场、食品厂、肉类加工、生活污水、油田废水、造纸厂、电镀、洗煤、印染、漂染等废水净化处理。 Purifying the composite produced by the above method is applied to livestock farms, food factories, meat processing, sewage, waste oil, paper mills, electroplating, washing, dyeing, bleaching and dyeing waste water purification. 其单位使用量比单一型硫酸铝低15%以上。 Units as compared to the one-type lower than 15% aluminum sulfate. 而且对惰性污染物去除效果尤为显著。 Further inert contaminant removal effect is particularly significant. 对改善环境污染,保护水资源提供一种新的方法。 To provide a new method to improve the environment, protect water resources.
