工業(yè)廢水處理設(shè)備主要應(yīng)用在哪些行業(yè)?
1. Wastewater treatment equipment used in: hydrolysis acidification tank
該工藝主要處理的就是對(duì)廢水處理前進(jìn)行預(yù)處理,將水中的廢水進(jìn)行一定的厭氧發(fā)酵,將廢水的可生化性提高,這是對(duì)廢水處理前比較重要的步驟,可以直接影響后期的廢水處理的效率和處理時(shí)間,可以最大程度的提高廢水處理的效率和減少消耗。
The main treatment of this process is to pretreat the wastewater before treatment. The wastewater in the water is subject to certain anaerobic fermentation to improve the biodegradability of wastewater. This is an important step before wastewater treatment, which can directly affect the efficiency and treatment time of wastewater treatment in the later stage, and can maximize the efficiency of wastewater treatment and reduce consumption.
2、工業(yè)廢水處理設(shè)備運(yùn)用于:接觸氧化池
2. Industrial wastewater treatment equipment: contact oxidation tank
氧化池根據(jù)水處理的污染程度不同分為好幾個(gè)等級(jí),普通型和加強(qiáng)型。一般根據(jù)處理的時(shí)間進(jìn)行判斷。處理時(shí)間不大于四個(gè)小時(shí)就使用普通型的氧化池,處理時(shí)間在4-6小時(shí)之間的使用加強(qiáng)型的氧化池。主要是使用水解酸化池出水自流至接觸氧化池進(jìn)行生化處理。原廢水中大部分有機(jī)物在此得到降解和凈化,好氧菌以填料為載體,利用廢水中的有機(jī)物為食料,將廢水中的有機(jī)物分解成無機(jī)鹽類,從而達(dá)到凈化目的。好氧菌的生存,必須有足夠的氧氣,即廢水中有足夠的溶解氧,以達(dá)到生化處理的目的。
According to the pollution degree of water treatment, oxidation tank can be divided into several grades, ordinary type and enhanced type. It is generally judged according to the processing time. If the treatment time is not more than four hours, the ordinary oxidation tank is used, and the treatment time is less than four hours - 6 hours between the use of enhanced oxidation tank. It mainly uses hydrolytic acidification tank effluent to flow to contact oxidation tank for biochemical treatment. Most of the organic matter in the original wastewater is degraded and purified here. Aerobic bacteria take the filler as the carrier and use the organic matter in the wastewater as the food to decompose the organic matter in the wastewater into inorganic salts, so as to achieve the purpose of purification. The survival of aerobic bacteria must have enough oxygen, that is, there is enough dissolved oxygen in waste water to achieve the purpose of biochemical treatment.
3、工業(yè)廢水處理設(shè)備運(yùn)用于:雜質(zhì)沉淀池
3. Industrial wastewater treatment equipment used in: impurity sedimentation tank
廢水經(jīng)過生物接觸氧化池處理后出水自流進(jìn)入沉淀池,進(jìn)一步沉淀去除脫落的生物膜和部份有機(jī)及無機(jī)小顆粒,沉淀池是根據(jù)重力作用的原理,當(dāng)含有懸浮物的廢水從下往上流動(dòng)時(shí),由重力作用,將物質(zhì)沉淀下來。沉淀池上部設(shè)可調(diào)出水堰,以調(diào)節(jié)出水水位。下部設(shè)錐形沉淀區(qū)和污泥氣體裝置,氣源由風(fēng)機(jī)提供,污泥采用氣提方式輸送至污泥好氧消化池。
After the wastewater is treated by biological contact oxidation tank, the effluent flows into the sedimentation tank by itself to further precipitate and remove the detached biofilm and some organic and inorganic small particles. The sedimentation tank is based on the principle of gravity. When the wastewater containing suspended solids flows from bottom to top, the matter is precipitated by gravity. The upper part of the sedimentation tank is equipped with an adjustable weir to regulate the effluent water level. Conical sedimentation area and sludge gas device are set at the lower part. The air source is provided by the fan, and the sludge is transported to the sludge aerobic digestion tank by air lift.
4、廢水處理設(shè)備運(yùn)用于:消毒處理消毒池一般標(biāo)準(zhǔn)為30分鐘,若是醫(yī)院廢水,消毒池增加停留時(shí)間至1-1.5小時(shí)。我公司采用二氧化氯消毒裝置,消毒池與消毒裝置能根據(jù)出水量大小不斷改變加藥量,達(dá)到多出水多加藥,少出水少加藥的目的,需要其它裝置可另行配制。(如用于工業(yè)廢水,消毒池與消毒裝置可以不要
4. Application of wastewater treatment equipment: the general standard of disinfection pool is 30 minutes. If it is hospital wastewater, the residence time of disinfection pool is increased to 1 minute - one . Five hours. Our company adopts chlorine dioxide disinfection device. The disinfection pool and disinfection device can continuously change the dosage according to the volume of water, so as to achieve the purpose of more water and more medicine, less water and less medicine. If other devices are needed, they can be prepared separately. ( If it is used for industrial wastewater, the disinfection pool and disinfection device can not be used
5、廢水處理設(shè)備運(yùn)用于:污泥好氧消化
5. Application of wastewater treatment equipment: aerobic digestion of sludge
沉淀池所排放剩余污泥在池中進(jìn)行好氧消化穩(wěn)定處理,以減少污泥的體積和提高污泥的穩(wěn)定性。好氧消化后的污泥量較少,清理時(shí)可用吸糞車從污泥池的檢查孔伸到污泥池底部進(jìn)行抽吸后外運(yùn)即可(半年清理一次)。污泥好氧消化池上部設(shè)上清液回流裝置,使上清液溢流至水解酸化池。
In order to reduce the volume of sludge and improve the stability of sludge, the excess sludge discharged from the sedimentation tank is treated by aerobic digestion and stabilization in the tank. The amount of sludge after aerobic digestion is small, so the suction truck can be used to extend from the inspection hole of the sludge tank to the bottom of the sludge tank for suction before transportation ( Once every six months )。 A supernatant reflux device is set at the upper part of the sludge aerobic digestion tank to overflow the supernatant to the hydrolysis acidification tank.
