污油泥处理的技术、污泥处理和工业污泥分离方法是什么?1、油田钻井废泥浆水处理方法2、含油泥浆冲洗液及其制备方法3、油井水泥脱水剂复合物4、油泥加工批量燃料油制备方法5、石化厂污水处理厂生产污泥处理方法6、石油、天然气钻井自动排泥装置7、含油泥调和渣油的制备方法8、快硬早强油。

What are the techniques of sludge treatment, sludge treatment and industrial sludge separation? 1, 2 oil field drilling waste mud water treatment method, oily mud flushing fluid and its preparation method 3, oil well cement dehydrating compound 4, sludge processing bulk fuel oil preparation methods 5, 6 petrochemical factory sewage treatment plant sludge treatment method, oil, natural gas drilling mud device automatically 7, including the preparation methods of the sludge and residue 8 oil, rapid hardening, early strength.

 

污油泥处理一般分为一级处理和二级处理。初级处理是将油馏油、分散状态油和油泥从水和乳化谷中分离出来。二次处理是破坏油一水乳液,分离剩余油。

Sludge treatment is generally divided into primary treatment and secondary treatment. The primary treatment is the separation of oil distillate, dispersed oil and sludge from water and emulsified valley. The secondary treatment is to destroy the oil in a water emulsion and separate the remaining oil.

 

污油泥处理的油类水废油主要以漂浮油、乳化油、溶解油三种形式存在,它们根据水中油股分布图进行划分。浮油:油珠颗粒大小较大,一般大于100m,容易分离和浮油,占总流量的80% ~ 90%。乳化油:粒径小,一般小于10m,悬浮液,不易分离,约占10% ~ 15%。溶解油:与分子溶解相似,约占0.2% ~ 0.5%。

The waste oil of oily sludge treatment mainly exists in three forms: floating oil, emulsified oil and dissolved oil, which are divided according to the distribution map of oil stocks in water. Oil floating: the size of oil particles is large, generally larger than 100m, easy to separate and oil floating, accounting for 80% to 90% of the total flow. Emulsified oil: small particle size, generally less than 10m, suspension, not easy to separate, about 10% ~ 15%. Dissolved oil: similar to molecular dissolution, about 0.2% ~ 0.5%.

 

污油泥处理的膜生物反应器(MBR)由MF、UF或NF膜组件和生物反应器组成,常用于污水处理的是将活性污泥与该膜结合。膜过程相当于现有活性污泥过程中的二次沉淀池。因此,将活性污泥与净化后的水分离,将污泥送回反应器,提高耐火材料的去除率,提高反应器内污泥浓度,NF膜减少有机物和高价盐拦截,提高在反应器中的停留时间,通过活性污泥的分解和吸附进一步去除。因此,MBR非常适合生物降解。

Membrane bioreactor (MBR) for sludge treatment consists of MF, UF or NF membrane components and bioreactor, and is commonly used for wastewater treatment by combining activated sludge with this membrane. The membrane process is equivalent to the secondary sedimentation tank in the existing activated sludge process. Therefore, the activated sludge is separated from the purified water, and the sludge is returned to the reactor to improve the removal rate of refractory materials, improve the concentration of sludge in the reactor, NF membrane reduces the interception of organic matter and high salt, improve the residence time in the reactor, and further remove by the decomposition and adsorption of activated sludge. Therefore, MBR is well suited for biodegradation.

 

20世纪90年代,研究人员开发了MBR工艺,MF膜部件和生物反应过程的组合,这种MBR工艺简化了膜装置的结构,降低了投资成本,操作、维修更加方便,占地小,因此,MBR及其工艺的开发和商品化大大促进了膜技术在水再利用中的应用。

In the 1990 s, researchers have developed MBR process, the combination of MF membrane components and biological reaction process, the MBR technology simplifies the structure of the membrane device, reduces the cost of investment, operation and maintenance more convenient, covers an area of small, as a result, the MBR and its process of development and commercialization of greatly promote the application of membrane technology in water reuse.

 

近年来,我国的MBR技术已应用于部分城市生活污水处理和再利用,吞吐量为5-500M3/d,处理的污水有生活污水、医院废水、洗车水等。我国已将膜技术的工业节水和中水回收纳入“十五”科技攻关重点项目,以节约水资源,达到减少和控制污染的目的。

In recent years, China's MBR technology has been applied in some urban sewage treatment and reuse, throughput of 5-500m3 /d, sewage treatment, hospital wastewater, car wash water, etc. In order to save water resources and achieve the purpose of reducing and controlling pollution, China has brought the industrial water saving and reclaimed water of membrane technology into the "tenth five-year plan" scientific and technological key projects.

 

污油泥处理的中水回用也采用了活性污泥。是生物接触氧化、陶瓷膜分离、二氧化氯杀菌三相组合MBR装置,该装置已正常运行3年多,取得了良好效果,其特点是装置运行稳定、水质好、剩余污泥少、运行成本低。2005年6月,使用了絮凝气浮、生物接触氧化、道膜分离和臭氧消毒的组合。

Activated sludge is also used for water reuse in sludge treatment. It is a three-phase combined MBR device of biological contact oxidation, ceramic membrane separation and chlorine dioxide sterilization. The device has been in normal operation for more than 3 years and achieved good results. It is characterized by stable operation, good water quality, less residual sludge and low operating cost. In June 2005, a combination of flocculated air flotation, biological contact oxidation, membrane separation and ozone disinfection was used.
