Background
With the recent continuous development of industry, sewage treatment is an urgent problem to be solved, and among various methods for sewage treatment, coagulation sedimentation is a method frequently used. The coagulating sedimentation process is a process of adding a proper amount of coagulant into water, destroying the stability of colloidal particles and fine suspended matters in the water to enable the colloidal particles and the fine suspended matters to agglomerate, forming flocculating constituents (generally called alum flocs in water treatment) under the catching action of the flocculating constituents and certain hydraulic conditions, and separating the flocculating constituents from the water, wherein impurities removed by coagulating sedimentation mainly comprise suspended matters and colloidal particles. In water treatment, coagulation is the most critical factor affecting the treatment effect. The coagulation can not only make colloid and fine suspended matter in suspension agglomerate into particles which are easy to precipitate and separate, but also can partially remove chromaticity, inorganic pollutants, organic pollutants and colloid complex formed by iron and manganese. Meanwhile, some radioactive substances, plankton and algae can be removed. The quality of the reaction effect is directly related to the effluent quality and the treatment cost, and the treatment of tap water, domestic sewage and various industrial wastewater is required to be applied to the coagulating sedimentation process.
Conventional printing and dyeing wastewater is mainly destabilized by colloidal particles and fine suspended matters through a coagulation method, is aggregated into alum flocs of hundreds of micrometers to several millimeters, and then is settled through gravity, but because flocs with lighter mass can float on the water surface, partial flocs can not be settled through gravity, so that the wastewater recovery treatment effect is poor, and the efficiency is low.
