METHOD AND APPARATUS FOR TREATING NATURAL GAS AND OIL WELL DRILLING WASTE WATER
摘要
<p>A method of treating contaminated water effluent from a well drilling operation. The method comprises decomposing organic contaminants in the effluent by bubbling a gas containing ozone through the effluent; adding a coagulant to increase the particle size of solid particles contained in the effluent; adding a flocculant to increase the particle size of solid particles contained in the effluent, thereby forming floes suspended in the effluent; and filtering the floes from the effluent to produce a filtrate and flocculated solids. The method may further comprise adding the coagulant into a stream of effluent flowing within a first conduit under controlled shear conditions, and adding the flocculant into a stream of effluent containing pin floes flowing within a second conduit under controlled shear conditions. The method may further comprise delivering the effluent containing the suspended floes into a filter through a conduit floating in the effluent contained in the filter.</p>
