Lanthanum carbon wastewater is the wastewater generated during the medium- and low-temperature carbonization of coal (at 500–650°C); it mainly originates from the circulating water used to cool and wash the gas, as well as from the water produced during separation processes. Lan coal is a product of medium- and low-temperature carbonization of coal; during its production, a large amount of tar is generated, along with many low-molecular-weight organic substances. As a result, the wastewater contains a high concentration of pollutants that have not been oxidized at high temperatures, and this concentration is about 10 times higher than that of wastewater from high-temperature carbonization processes. In particular, the level of oily pollutants is even higher. Characteristics of lignite carbon wastewater: 1. High oil content, as high as 5000–10000 mg/L; 2. High phenol content, as high as 10000–20000 mg/L ； 3. High COD content, ranging from 38,000 to 65,000 mg/L ； Difficulty of treatment: 1. Most of the oil is emulsified oil, and it is difficult to remove it using physical methods ； 2. High oil content leads to easy clogging of the tower internals, coking of the tray plates, and frequent flooding ； 3. The effluent quality is unsatisfactory, preventing the biochemical process from continuing to operate. In light of the characteristics of this lignite coking wastewater, our company employs proprietary process packages and patented tower internals to effectively address these issues. The advantages of this process are as follows: 1. It effectively reduces the content of emulsified oil, with the water-oil content remaining at ≤200 ppm ； 2. The process uses anti-clogging, high-efficiency MP column internals, ensuring stable column operation ； 3. Recycle products to reduce operating costs ； 4. The technology is mature and reliable, with stable operation ； 5. Low energy consumption, 20% less than other processes. Industrial application: A company in Shenmu. Feel free to ask.
