油漆废水处理翻译-中英对照
1、油漆废水流入收集池中收集均匀水质并调整pH值在6.5左右,废水中的废油漆由於带有黏性,因此必须添加消黏剂防止残漆粘黏管道及设备,收集池废水以泵定量输送到气浮机

。在涡凹气浮机前段混凝区添加造渣剂将溶解的油漆混凝成絮体,利用溶解空气将油漆杂质托送至水面,以刮泥机将污泥撇除排到污泥池存放,气浮机底部澄清水则排放到MBR池。
2、MBR池中培养好氧微生物,将废水中溶解性有机物进行消解,转化成生物污泥,再利用中空纤维膜将污泥与水分离,得到无悬浮物的处理水,流入清水池收集,清水池中的处理

水一部分作为MBR膜的反冲洗水源,其余则排到放流池排放。
3、MBR池的污泥定期抽送排到污泥池与气浮机刮除污泥一并进行脱水处理,滤液回流收集池重复处理,干污泥则委外最终处置。
4、当遇到生物单元有异常状况导致MBR处理水质COD较高时,则将清水池处理水输送到活性炭槽进行吸附处理,确保处理水达标。

3.0 主要工艺原理及特点
3.1 电化学废水处理设备简介
电化学机为一密闭槽体,通以直流电源将废水在槽中进行电化学反应,将废水中污染物质加以改变电性或是电解氧化以达到分离去除效果,因此简单地说可以将电化学机当成一电

解反应槽,透过直流电在阳极与阴级的反应将污染物在此电解分离。
3.1.1 电化学处理机制
3.1.1. Electrochemistry processing mechanism
1.阳极氧化反应
1. Anodic oxidation reaction 
⑴金属极隔板氧化成金属离子:电化学机机体内常用的极板和隔板为铁质板,在通电时阳极产生电解作用,将铁电解成为铁离子,而这些不同型态的铁离子恰好是去除分离污染物

质所不可或缺的混凝剂,透过离子表面的电性而破坏污染物质的稳定进一步加以分离。
(1).The baffle of metal carbonyl electrode is oxidized to metal ions;the polar plate and baffle inside the electrochemistry unit are iron plate, the

electrolysis action may be occurred when the current is switched on the positive pole, and electrolyzed iron into the iron ion. And different form of iron ion is the indispensable coagulant to get rid of and separate polluter, which destroy stability of polluter through the electric property of iron ion surface and implement the further separating process.
⑵水分子电解形成微细氧气气泡:废污水在电解时会产生极细气泡,在阳极表面产生的为氧气气泡,这些气泡会与污染物质颗粒结合,使污染物上浮速度增快。
(2).The water moisture electrolysis may form micro-fine bubble of oxygen: It will produce the superfine bubble when being electrolysis the effluent sewage, and produced the oxygen bubble on the surface of positive pole. These bubbles will be combined with polluter and particle, and the speed for pollutant to floating upward will be increased quickly.
⑶初生态氧对污染物质及色度物质氧化:在阳极板电解过程中,于阳极铁板表面会产生不断的电解氧化作用,其中在过程中会产生一种高氧化能力的初生态氧原子,对污染物的氧化破坏或是色度物质的氧化脱色能力十分有效。
(3).The oxidation of nascent oxygen to the polluter and color material: during the process of positive plate electrolysis, it will produce the constant electrolysis oxidation on the iron plate surface of positive pole. During this process it will produce one nascent oxygen atom with high electrolysis

ability, which has a very effective ability to destroy or discolor the color material of pollutant.
2.阴极还原反应
2. The reduction reaction of negative pole
⑴水分子分解成微细氢气气泡及OH-:水在阴极会电解产生微细氢气气泡同样会与污染物质结合,使污染物上浮速度增快。另外在阴极所产生的氢氧根则是重金属去除时所不可或缺的离子,可将重金属污染物改变为溶解性较差的状态,以利于自废水中分离。
(1). The water moisture resolve into micro-fine bubble of hydrogen and OH-: Water will electrolyze and produce micro-fine bubble of hydrogen and combine with the polluter as well in the negative pole, and increase the speed of pollutant to floating upward. In addition the hydroxide radical produced in the negative pole is the indispensable ion in case of removing the heavy metal ion. It can change the heavy metal pollutant into dissolving worse state in order to benefit to separate it from the waste water.
⑵金属离子还原反应:废水中的金属离子在电化学反应时,部分会在阴极产生还原反应,而与铁质结合进而自水中分离。
(2).The metal ion reduction reaction: Some metal ion of the waste water will produce reduction reaction in negative pole in the electric chemical reaction and combine with the iron and then separate from the water.
3.混凝作用
3. Coagulation effect
⑴金属离子形成氢氧化合物:在阴极所产生的氢氧根与电解分离的铁形成数种氢氧化合物型态,产生具混凝效果的混凝物质。
(1).The hydrated oxide formed by metal ion: The hydroxide radical produced in the negative pole may form into several kinds of hydrated oxide with electrolyzed iron ion, and produced the coagulation t materials with congealing result.
⑵氢氧化合物与污染物质形成胶羽:这些不同的氢氧化合物会与污染物质快速结合产生许多微细颗粒。
(2).Hydrated oxide may combine with polluter and form floc: It produces a lot of micro-fine particles by the quick combination of these different hydrated

oxides and the polluters.
⑶胶羽碰撞结合形成棉絮状污泥:由于颗粒间的碰撞凝聚,加上微细气泡结合,使产生的胶体呈现棉絮状,胶羽比重较小适合浮除分离。
(3).The floc may collide and form the mud of cotton fiber: Due to the collision and condensation among the particles, and with the combination of micro-fine bubble, the floc showed a structure of cotton fiber. The proposition
