Abstract

The invention relates to a hydraulic concrete filter applied to the industries such as municipal water treatment, petrochemical engineering, coal and the like to remove colloidal impurities and suspended impurities in a liquid. The hydraulic concrete filter comprises a columnar reaction tank, a lift pump, a water intake pipe, a discharge pipe, a throat pipe, a cant board and a header tank. The hydraulic concrete filter disclosed by the utility utilizes the principle of hydraulic action to replace mechanical agitation, adopts compartment reaction, cant board filtering and negative pressure hydraulic potion to mix, and is widely applied to liquid wastes and waste water containing high suspended solids and colloid in municipal and industrial and mining enterprises for oilfield water injection treatment, fracturing flowback fluid treatment, drilling mud slurry treatment, emulsified oil treatment, coal chemical industry coal washing liquid treatment, circulating water treatment in steel mills, refinery wastewater treatment and the like.

Description

technical field [0001] The invention belongs to the field of sewage treatment, and in particular relates to a hydraulic coagulation filter and a hydraulic coagulation sludge thickener for removing colloidal impurities and suspended impurities in liquids in municipal water treatment, petrochemical, coal and other industries. Background technique [0002] The existing coagulation method for wastewater treatment is to add water treatment flocculant into the reaction tank, fully stir the reaction, generate flocs, and then realize mud-water separation in the sedimentation separation tank. Adding a flocculant to remove suspended and colloidal impurities in the liquid is a conventional and effective method. However, due to the effects of long reaction time and large temperature influence, the treatment effect of the coagulant on the liquid is not easy to control; the stirring of the coagulant is not conducive to The impurities in the liquid are adsorbed and settled by the floc acti...
