煤炼油厂的污水中含有大量酚、氨及有机酸等物。其中酚类毒性很大,对人对农作物皆有害,在水中含酚9—15毫克/升时,魚类卽被毒死,飲用水含酚达五亿分之一时,即无法飲用,煤成堆干餾厂污水含酚約300毫克/升(污水含酚量随不同煤种而有所不同),因此不能直接将污水放入农田、河流及下水道中,必須使污水中含酚量大大降低才能外放。炼油厂中污水处理問題一直没有很好解决,尤其在煤成堆干馏厂遍地开花的情况下,污水处理更成为
Coal refinery wastewater contains a lot of phenol, ammonia and organic acids and other objects. Among them, the phenols are very toxic and harmful to crops. When the water contains 9-15 mg / L of phenols, the fishes of the fish are poisoned and the amount of phenol in the drinking water reaches one in 500 million, which means they can not drink coal. Piles of dry distillation plant effluent phenols about 300 mg / L (sewage phenol content varies with different coal), it can not be directly into the sewage farmland, rivers and sewers, the sewage must be greatly increased the amount of phenol Lowering can be carried out. The problem of wastewater treatment in oil refineries has not been well solved, especially in the case of coal pyrolysis plant flowering everywhere, the sewage treatment becomes more
