定期捞取由格栅截留下的杂物，装入小车倾倒垃圾场。沉淀池中的污泥部分经回流泵回流生物水解酸化池，另一部分污泥则进入污泥池;经气浮处理的浮渣也进入污泥池。污泥池中污泥由污泥脱水机进行浓缩，泥饼外运填埋。二氯甲烷厂家污泥池上清液回流调节池再处理。
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.
二氯甲烷厂家废水经管网收集后进入格栅井，以去除废水中的漂流物和大颗粒杂质。格栅井出水进入调节池，进行水量水质均化调节。调节池出水由提升泵送水解酸化池，进行酸化水解和硝化反硝化，以降低有机物浓度。水解酸化池出水自流进入接触氧化池进行好氧生化反应，在此绝大部分有机污染物通过生物氧化、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.
在有机合成中，经常需要用二氯甲烷厂家二氯曱烷做溶剂，为了节约成本，二氯曱烷通常需要反复回收使用，从母液中回收的二氯曱烷往往混有5%—20%的水分，会影响下步合成反应，在下次使用前，需要把水分除掉。通常的除水方法是蒸馏、干燥等方式，但由于二氯曱烷的特性，采用通常方法处理回收二氯曱烷中的水分反而很困难，除水的效果不彻底，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.
