油漆廢水處理翻譯-中英對照
1、油漆廢水流入收集池中收集均勻水質(zhì)并調(diào)整pH值在6.5左右,廢水中的廢油漆由於帶有黏性,因此必須添加消黏劑防止殘漆粘黏管道及設(shè)備,收集池廢水以泵定量輸送到氣浮機(jī)

。在渦凹?xì)飧C(jī)前段混凝區(qū)添加造渣劑將溶解的油漆混凝成絮體,利用溶解空氣將油漆雜質(zhì)托送至水面,以刮泥機(jī)將污泥撇除排到污泥池存放,氣浮機(jī)底部澄清水則排放到MBR池。
2、MBR池中培養(yǎng)好氧微生物,將廢水中溶解性有機(jī)物進(jìn)行消解,轉(zhuǎn)化成生物污泥,再利用中空纖維膜將污泥與水分離,得到無懸浮物的處理水,流入清水池收集,清水池中的處理

水一部分作為MBR膜的反沖洗水源,其余則排到放流池排放。
3、MBR池的污泥定期抽送排到污泥池與氣浮機(jī)刮除污泥一并進(jìn)行脫水處理,濾液回流收集池重復(fù)處理,干污泥則委外最終處置。
4、當(dāng)遇到生物單元有異常狀況導(dǎo)致MBR處理水質(zhì)COD較高時,則將清水池處理水輸送到活性炭槽進(jìn)行吸附處理,確保處理水達(dá)標(biāo)。

3.0 主要工藝原理及特點(diǎn)
3.1 電化學(xué)廢水處理設(shè)備簡介
電化學(xué)機(jī)為一密閉槽體,通以直流電源將廢水在槽中進(jìn)行電化學(xué)反應(yīng),將廢水中污染物質(zhì)加以改變電性或是電解氧化以達(dá)到分離去除效果,因此簡單地說可以將電化學(xué)機(jī)當(dāng)成一電

解反應(yīng)槽,透過直流電在陽極與陰級的反應(yīng)將污染物在此電解分離。
3.1.1 電化學(xué)處理機(jī)制
3.1.1. Electrochemistry processing mechanism
1.陽極氧化反應(yīng)
1. Anodic oxidation reaction 
⑴金屬極隔板氧化成金屬離子:電化學(xué)機(jī)機(jī)體內(nèi)常用的極板和隔板為鐵質(zhì)板,在通電時陽極產(chǎn)生電解作用,將鐵電解成為鐵離子,而這些不同型態(tài)的鐵離子恰好是去除分離污染物

質(zhì)所不可或缺的混凝劑,透過離子表面的電性而破壞污染物質(zhì)的穩(wěn)定進(jìn)一步加以分離。
(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水分子電解形成微細(xì)氧氣氣泡:廢污水在電解時會產(chǎn)生極細(xì)氣泡,在陽極表面產(chǎn)生的為氧氣氣泡,這些氣泡會與污染物質(zhì)顆粒結(jié)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初生態(tài)氧對污染物質(zhì)及色度物質(zhì)氧化:在陽極板電解過程中,于陽極鐵板表面會產(chǎn)生不斷的電解氧化作用,其中在過程中會產(chǎn)生一種高氧化能力的初生態(tài)氧原子,對污染物的氧化破壞或是色度物質(zhì)的氧化脫色能力十分有效。
(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.陰極還原反應(yīng)
2. The reduction reaction of negative pole
⑴水分子分解成微細(xì)氫氣氣泡及OH-:水在陰極會電解產(chǎn)生微細(xì)氫氣氣泡同樣會與污染物質(zhì)結(jié)合,使污染物上浮速度增快。另外在陰極所產(chǎn)生的氫氧根則是重金屬去除時所不可或缺的離子,可將重金屬污染物改變?yōu)槿芙庑暂^差的狀態(tài),以利于自廢水中分離。
(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金屬離子還原反應(yīng):廢水中的金屬離子在電化學(xué)反應(yīng)時,部分會在陰極產(chǎn)生還原反應(yīng),而與鐵質(zhì)結(jié)合進(jìn)而自水中分離。
(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金屬離子形成氫氧化合物:在陰極所產(chǎn)生的氫氧根與電解分離的鐵形成數(shù)種氫氧化合物型態(tài),產(chǎn)生具混凝效果的混凝物質(zhì)。
(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氫氧化合物與污染物質(zhì)形成膠羽:這些不同的氫氧化合物會與污染物質(zhì)快速結(jié)合產(chǎn)生許多微細(xì)顆粒。
(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膠羽碰撞結(jié)合形成棉絮狀污泥:由于顆粒間的碰撞凝聚,加上微細(xì)氣泡結(jié)合,使產(chǎn)生的膠體呈現(xiàn)棉絮狀,膠羽比重較小適合浮除分離。
(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
