Water treatment in aniline production
Thread Content
After reviewing some materials, very little practical experience regarding the treatment of aniline wastewater was found, especially a lack of compelling data. It cannot be applied in actual laboratory practices, and sometimes it can hinder the development of businesses. I have the following questions for everyone: 1. Is electrocoagulation really effective? 2. The previous step in aniline production is *** production; how to control the concentration of ***? Because *** is hard to remove. 3. For an aniline plant with an annual production capacity of 30,000 tons, along with the associated *** facilities, is 300 m3 of wastewater per day much or little? Note: Due to strict environmental regulations, our wastewater control is based on COD
Without other measures, the effectiveness of electrocoagulation is limited. Controlling the concentration of *** in the process is crucial; air stripping plays an important role in this regard. Many companies keep the *** concentration below 110. For 30,000 tons of aniline wastewater, the volume should be a little over 100 cubic meters, not reaching 200 cubic meters. The wastewater treatment system we designed for 300,000 tons of aniline wastewater has a capacity of 80 cubic meters per hour. The composition of this water is relatively simple, and by using appropriate treatment processes, it can be stabilized to meet the local standards of Shandong.
Well, it’s about applying it in practice! Is the gas lift mentioned earlier related to wastewater treatment? There will be an aniline water treatment tower that can keep the aniline concentration at 1 g/L, with a COD level of around 4000. My QQ number is 33214891; feel free to communicate more!
Yes, gas lift is generally considered in terms of the process. The wastewater parameters controlled by an aniline factory in Hebei are as follows: Waste water type, Waste water flow rate (m3/h), *** (mg/L), Aniline (mg/L), pH, Temperature (℃). *** For normal wastewater: 15.0, <100, 7–9, 50; for aniline-containing wastewater: 4.0, <400, 7–8, 50. These figures refer to a plant with an annual production capacity of 60,000 tons of aniline. The management level of this factory is quite good.
Thank you! This processing level is really good!
