工业废水处理设备主要应用在哪些行业?
1. Wastewater treatment equipment used in: hydrolysis acidification tank
该工艺主要处理的就是对废水处理前进行预处理,将水中的废水进行一定的厌氧发酵,将废水的可生化性提高,这是对废水处理前比较重要的步骤,可以直接影响后期的废水处理的效率和处理时间,可以的提高废水处理的效率和减少消耗。
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、工业废水处理设备运用于:接触氧化池
2. Industrial wastewater treatment equipment: contact oxidation tank
氧化池根据水处理的污染程度不同分为好几个等级,普通型和加强型。一般根据处理的时间进行判断。处理时间不大于四个小时就使用普通型的氧化池,处理时间在4-6小时之间的使用加强型的氧化池。主要是使用水解酸化池出水自流接触氧化池进行生化处理。原废水中大部分有机物在此得到降解和净化,好氧菌以填料为载体,利用废水中的有机物为食料,将废水中的有机物分解成无机盐类,从而达到净化目的。好氧菌的生存,必须有足够的氧气,即废水中有足够的溶解氧,以达到生化处理的目的。
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、工业废水处理设备运用于:杂质沉淀池
3. Industrial wastewater treatment equipment used in: impurity sedimentation tank
废水经过生物接触氧化池处理后出水自流进入沉淀池,进一步沉淀去除脱落的生物膜和部份有机及无机小颗粒,沉淀池是根据重力作用的原理,当含有悬浮物的废水从下往动时,由重力作用,将物质沉淀下来。沉淀池上部设可调出水堰,以调节出水水位。下部设锥形沉淀区和污泥气体装置,气源由风机提供,污泥采用气提方式输送污泥好氧消化池。
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、废水处理设备运用于:处理池一般标准为30分钟,若是医院废水,池增加停留时间1-1.5小时。我公司采用二氧化氯装置,池与装置能根据出水量大小不断改变加药量,达到多出水多加药,少出水少加药的目的,需要其它装置可另行配制。(如用于工业废水,池与装置可以不要
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、废水处理设备运用于: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进行好氧消化稳定处理,以减少污泥的体积和提高污泥的稳定性。好氧消化后的污泥量较少,清理时可用吸粪车从污泥池的检查孔伸到污泥池底部进行抽吸后外运即可(半年清理一次)。污泥好氧消化池上部设上清液回流装置,使上清液溢流水解酸化池。
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.
