Abstract

The invention discloses a pulse electric flocculation device for color and turbidity removal of source water and a use method of the pulse electric flocculation device, and relates to the field of wastewater treatment. The technical problem that existing wastewater treatment is poor in treatment effect is solved. The device comprises an electric flocculation reactor and a bidirectional pulse power supply, the electric flocculation reactor comprises a cylindrical reactor, an iron electrode plate, an aluminum electrode plate and a flange plate, and the cylindrical reactor is a horizontal reactor. According to the pulse electric flocculation device, the removal effect on chromaticity, turbidity, UV254, micro-pollution organic matters and micro-pollution inorganic matters in water treatment is remarkably improved, and the drinking water safety of a small-scale water treatment system can be effectively improved. The pulse electric flocculation device is used for removing turbidity, chromaticity and micropollutants in water of a micro-polluted water source.

Description

technical field [0001] The invention relates to the field of wastewater treatment. Background technique [0002] my country has a vast territory and uneven population distribution. In rural areas with low population density, it is often impossible to build water treatment facilities due to technological and economic backwardness. Excessive turbidity and chromaticity will lead to cloudy and colored drinking water, which will make drinkers feel insecure and disgusted, and rural areas often have problems such as old facilities, backward economy, and lack of high-level management personnel. Therefore, there is a need for a set of water treatment equipment that is safe and effective, easy to operate, convenient to maintain and manage, and low in operating costs. Electrocoagulation technology is widely used in the industrial field as a wastewater treatment technology. Its principle of action is to electrolyze the motor plate through an external current, and the metal cations and hy...
