Gas field oily sludge tempering and dehydration method

The invention discloses a gas field oily sludge tempering and dehydration method comprising the steps of adding a potassium salt to to-be-treated oily sludge at normal temperature under normal pressure, and stirring for 10 to 20 minutes; then adding quicklime and reacting for 10 to 20 minutes; adding sodium hydroxide, stirring for 10 to 20 minutes, and finally press-filtering. The method is low inraw material cost, readily available in raw materials, simple in process conditions, short in treatment time and stable in reaction, is beneficial to automatic treatment of a large amount of oily sludge, and has good tempering effect and high degree of sludge dehydration. At the same time, the potassium permanganate can kill parasite eggs, pathogenic bacteria and the like in the sludge by strongoxidation to achieve a bactericidal effect, so that pathogenic bacteria are unlikely to produce, and the method is beneficial to environmental protection. 本发明公开了种气田含油污泥调质脱水方法，在常温常压条件下，向待处理含油污泥中加入钾盐，搅拌处理10～20分钟；然后加入生石灰，反应10～20分
