二氯甲烷廢水應該如何進行處理!

定期撈取由格柵截留下的雜物,裝入小車傾倒垃圾場。沉淀池中的污泥部分經回流泵回流生物水解酸化池,另一部分污泥則進入污泥池;經氣浮處理的浮渣也進入污泥池。污泥池中污泥由污泥脫水機進行濃縮,泥餅外運填埋。二氯甲烷廠家污泥池上清液回流調節(jié)池再處理。
Regularly pick up the sundries intercepted by the grid, load them into the trolley and dump them to the garbage dump. Part of the sludge in the sedimentation tank returns to the biological hydrolysis acidification tank through the return pump, and the other part of the sludge enters the sludge tank; The scum treated by air flotation also enters the sludge tank. The sludge in the sludge tank is concentrated by the sludge dehydrator, and the sludge cake is transported out for landfill. The supernatant from the sludge tank of dichloromethane manufacturer returns to the regulating tank for reprocessing.
二氯甲烷廠家廢水經管網收集后進入格柵井,以去除廢水中的漂流物和大顆粒雜質。格柵井出水進入調節(jié)池,進行水量水質均化調節(jié)。調節(jié)池出水由提升泵送水解酸化池,進行酸化水解和硝化反硝化,以降低有機物濃度。水解酸化池出水自流進入接觸氧化池進行好氧生化反應,在此絕大部分有機污染物通過生物氧化、吸附得以降解。
The waste water from the dichloromethane manufacturer is collected by the pipe network and first enters the grid well to remove the drift and large particle impurities in the waste water. The outlet water from the grid well enters the regulating tank for water quantity and quality homogenization regulation. The effluent from the regulating tank is pumped to the hydrolysis and acidification tank by lift pump for acidification, hydrolysis, nitrification and denitrification to reduce the concentration of organic matter. The effluent from the hydrolysis acidification tank flows into the contact oxidation tank for aerobic biochemical reaction, where most organic pollutants are degraded through biological oxidation and adsorption.
在有機合成中,經常需要用二氯甲烷廠家二氯曱烷做溶劑,為了節(jié)約成本,二氯曱烷通常需要反復回收使用,從母液中回收的二氯曱烷往往混有5%—20%的水分,會影響下步合成反應,在下次使用前,需要把水分除掉。通常的除水方法是蒸餾、干燥等方式,但由于二氯曱烷的特性,采用通常方法處理回收二氯曱烷中的水分反而很困難,除水的效果不徹底,而且成本4交高。
In organic synthesis, dichloromethane manufacturer's dichloromethane is often used as solvent. In order to save cost, dichloromethane usually needs to be recycled repeatedly. The dichloromethane recovered from mother liquor is often mixed with 5% - 20% water, which will affect the next synthesis reaction. The water needs to be removed before next use. The usual water removal methods are distillation, drying, etc. However, due to the characteristics of dichloromethane, it is difficult to treat and recover the water in dichloromethane by the usual methods, the effect of water removal is not complete, and the cost is 4 high.
