Abstract

The invention relates to a hydraulic coagulation sludge thickener used for removing colloidal impurities and suspended impurities in liquid in industries such as municipal water treatment, petrochemical engineering and coal industry. The hydraulic coagulation sludge thickener comprises a columnar reaction tank, a lifting pump, a water inlet pipe, a water outlet pipe, a throat pipe, an inclined plate and a water collection tank. According to the hydraulic coagulation sludge thickener, mechanical stirring is replaced by utilizing a principle of a hydraulic action, split chamber reaction, inclined plate filtering and negative pressure hydraulic agent mixing are adopted, the coagulation filtering and sludge thickening efficiency is high, and the hydraulic coagulation sludge thickener is widely applied in oilfield reinjection water treatment, fracturing flow-back liquid treatment, drilling fluid treatment, emulsified oil treatment, coal chemical industry coal-washing fluid treatment, steel mill circulating water treatment, refinery enterprise wastewater treatment and high-suspension, colloidal waste liquid and wastewater in municipal and industrial and mining enterprises.

Description

technical field [0001] The invention belongs to the field of sewage treatment, and in particular relates to a hydraulic coagulation sludge thickener and a hydraulic coagulation filter for removing colloidal impurities and suspended matter 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 fl...
