Zero Emission Technology Monitoring Indicators for Petrochemical Industry

by:BOQU     2023-03-17
With the rapid development of our country's economy, the problems of resources and environment have been paid attention to by everyone. Among them, water environmental pollution is a headache. Doing a good job in sewage treatment and ensuring water quality is the current purpose. In this way, the requirements for petrochemical wastewater treatment will become higher and higher. In this article, we will learn about the monitoring indicators of wastewater in stone refineries with manufacturers of online water quality monitors. Let me first talk about several wastewater monitoring points in petroleum refineries, such as the general discharge outlet, workshop or production facility wastewater discharge outlet, and rainwater discharge outlet, where water quality detectors need to be installed for operation. The specific monitoring indicators are as follows: 1. Total wastewater discharge outlet: flow rate, chemical oxygen demand, ammonia nitrogen, petroleum, pH value, suspended solids, total nitrogen, total phosphorus, sulfide, volatile phenol, total organic carbon, total vanadium, Benzene, toluene, o-xylene, m-xylene, p-xylene, ethylbenzene, total cyanide, etc.; 2. Delayed coking unit cold coke water, coke cutting water waste water outlet: benzopyrene; 3. Atmospheric and vacuum distillation Wastewater discharge port of electric desalination device: total mercury, alkylmercury; 4. Wastewater discharge port of acidic water stripping device: total arsenic; Total nickel; 6. Wastewater from tetraethyl lead production unit and waste water from aviation gasoline blending workshop: total lead; 7. Rainwater discharge: pH value, chemical oxygen demand, ammonia nitrogen, petroleum, suspended solids; Pay attention to the following points: 1. Install automatic detection equipment to monitor its indicators in real time; 2. When monitoring the concentration of pollutants, it is necessary to monitor the flow rate simultaneously; 3. Monitor daily during the discharge period. When it comes to oil refining, it is an important part of oil work. It is mainly processed in oil refining engineering to serve various oil product industries. The sewage of oil refining industry has high salt content and large changes in water volume, etc. characteristics, and often form impact loads. In addition, some sewage that has been treated by the sewage treatment system still has a large amount of refractory organic matter. Therefore, it is more appropriate to adopt the zero-discharge technical solution of the petrochemical industry for this kind of wastewater.
