Electronic flocculation treatment method under low-turbidity water quality condition

Abstract

The invention discloses an electronic flocculation treatment method under a low-turbidity water quality condition. The method comprises the following steps: A, firstly, introducing low-turbidity sewage into a raw water regulating tank for preliminary adjustment; B, treating pre-treated sewage, applying current to water body in a device by dissolvable plates and current generators in an adjusting cell, and coagulating particulate matters in the water to form flocculent precipitate; C, electrifying the low-turbidity water after flocculation again to react, demulsifying the low-turbidity sewage,and bleaching; D, subsequently, injecting the pre-treated low-turbidity sewage into a centrifugal clarifier for centrifugation; and E, separating precipitated flocculants from clean water. In the method disclosed by the invention, an electronic flocculant technology is used for treating the low-turbidity water in a high-speed and high-efficiency manner, and the organic combination of a water treatment technology, an automation control technology and a computer technology is used for treating the low-turbidity water, so that the staffing and labor intensity are reduced, and the automation levelof an enterprise is improved.

Description

technical field [0001] The invention relates to the technical field of low turbidity wastewater treatment, in particular to an electronic flocculation treatment method under low turbidity water quality conditions. Background technique [0002] With the development of my country's economy, the increase of population, the continuous acceleration of urbanization process and the continuous expansion of scale, environmental and health issues have attracted more and more attention. [0003] At present, there are many low turbidity water treatment methods, such as flocculation sedimentation, mechanical accelerated sedimentation, slow decarbonization, biological trickling filtration, etc. Among them, flocculation sedimentation and mechanical accelerated sedimentation are the most widely used technologies. The water quality of low turbidity water has little fluctuation, and the water load fluctuates greatly. Using large-scale treatment structures not only occupies a large area and wa...
