法兰式液位变送器应用:高盐废水二阶段阶段处理测控处理/高盐废水处理技术分析
Application of flange type liquid level transmitter: two-stage treatment, measurement and control treatment of high salt wastewater / technical analysis of high salt wastewater treatment
法兰式液位变送器应用:高盐废水二阶段阶段处理测控处理/（1）电解法。高矿化度废水由于其高矿化度而具有较高的电导率，使电化学降解高矿化度废水成为可能。在电解过程中，有机物电解质溶液可以发生一系列氧化还原反应从而降低COD。这种方法处理与有机物和无机盐的种类也有关，Cl-存在时可在阳极放电，生成ClO-降解COD，也有实验表明苯酚废水通过电解法处理只改变了COD的存在形式并没有减少TOC的存在总量。 达标后的中水排入高新区中水回用水池进行中水的冬储夏灌，降低的高新区绿化投入成本。公司将严守安全生产、稳定达标排放的原则，持之以恒的运行好污水处理厂，为高新区的碧水蓝天事业做小小的助力。
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.
法兰式液位变送器应用:高盐废水二阶段阶段处理测控处理/（2）膜分离过程。目前较成熟的常用的膜分离工艺有微滤、超滤、纳滤、反渗透四种，微滤和超滤所用膜的孔径较大，对于COD和悬浮物的截留作用较好，但不能截留大部分溶解性物质，纳滤可以截留大部分二价离子，反渗透能够截留一价离子，所以根据要求的不同可以选择不同的膜分离工艺进行处理，膜分离工艺处理效果好于一般工艺，成本较高，且膜污染问题较突出，因此受到了一定限制。目前还有一些新型膜分离工艺，如膜蒸馏工艺和清华大学研制的“NANO”膜。膜蒸馏工艺利用疏水膜的疏水性使水蒸气通过膜而隔离其他物质，从而保证出水洁净，膜蒸馏工艺同样存在膜结垢问题，且疏水膜的研制还不能满足大规模应用的要求。其结合反渗透和膜蒸馏的工艺特点，抗污染能力强，截留能力强，有良好的发展前景。
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.
