法蘭式液位變送器應(yīng)用:高鹽廢水二階段階段處理測(cè)控處理/（1）電解法。高礦化度廢水由于其高礦化度而具有較高的電導(dǎo)率，使電化學(xué)降解高礦化度廢水成為可能。在電解過(guò)程中，有機(jī)物電解質(zhì)溶液可以發(fā)生一系列氧化還原反應(yīng)從而降低COD。這種方法處理與有機(jī)物和無(wú)機(jī)鹽的種類(lèi)也有關(guān)，Cl-存在時(shí)可在陽(yáng)極放電，生成ClO-降解COD，也有實(shí)驗(yàn)表明苯酚廢水通過(guò)電解法處理只改變了COD的存在形式并沒(méi)有減少TOC的存在總量。 達(dá)標(biāo)后的中水排入高新區(qū)中水回用水池進(jìn)行中水的冬儲(chǔ)夏灌，降低的高新區(qū)綠化投入成本。公司將嚴(yán)守安全生產(chǎn)、穩(wěn)定達(dá)標(biāo)排放的原則，持之以恒的運(yùn)行好污水處理廠(chǎng)，為高新區(qū)的碧水藍(lán)天事業(yè)做小小的助力。
Flange type liquid level transmitter application: high salt waste water two-stage treatment measurement and control treatment / (1) electrolysis method. High salinity wastewater has high conductivity due to its high salinity, which makes electrochemical degradation of high salinity wastewater possible. In the process of electrolysis, a series of redox reactions can take place in the electrolyte solution of organic matter, which can reduce COD. This method is also related to the types of organic and inorganic salts. When Cl - exists, it can discharge at the anode to generate ClO - to degrade cod. Some experiments show that the electrochemical treatment of phenol wastewater only changes the existing form of COD and does not reduce the total amount of TOC. After reaching the standard, the reclaimed water will be discharged into the reclaimed water reuse pool of the high tech Zone for winter storage and summer irrigation, reducing the investment cost of afforestation in the high tech Zone. The company will strictly abide by the principle of safe production and stable discharge up to the standard, persistently operate the sewage treatment plant, and make a small contribution to the blue water and blue sky cause of the high-tech zone.

Application of flange type liquid level transmitter: high salt waste water two-stage treatment, measurement and control treatment / (2) membrane separation process. At present, there are four mature membrane separation processes: microfiltration, ultrafiltration, nanofiltration and reverse osmosis. The membrane used in microfiltration and ultrafiltration has large pore size, which has good retention effect on COD and suspended solids, but can not retain most of the soluble substances. Nanofiltration can retain most of divalent ions, and reverse osmosis can retain monovalent ions, so different membranes can be selected according to different requirements In the process of separation, the effect of membrane separation is better than that of general process, the cost is higher, and the problem of membrane pollution is more prominent, so it is limited to some extent. At present, there are some new membrane separation processes, such as membrane distillation process and "nano" membrane developed by Tsinghua University. Membrane distillation process uses the hydrophobicity of hydrophobic membrane to make water vapor pass through the membrane and isolate other substances, so as to ensure the cleanness of effluent. Membrane fouling also exists in membrane distillation process, and the development of hydrophobic membrane can not meet the requirements of large-scale application. Combined with the process characteristics of reverse osmosis and membrane distillation, it has strong anti pollution ability, strong retention ability and good development prospect.

Flange type liquid level transmitter application: high salt wastewater two-stage treatment, measurement and control treatment / emission concentration of relevant gaseous pollutants: NOx ≤ 50mg / m3, S02 ≤ 35mg / m3, smoke ≤ 10mg / m3. Many coal-fired boilers have been upgraded to meet the requirements of ultra-low emission, but the original CEMS system still remains in use. In order to meet the increasingly strict environmental protection requirements, in recent years, many coal-fired boilers have been actively using flange type liquid level transmitters: high salt waste water two-stage treatment, measurement and control treatment / environmental upgrading and transformation, so as to realize the "ultra-low emission" of gaseous pollutants such as soot, SO2, NOx in the flue gas of the boiler tail.
