Embodiment Construction
[0016] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0017] Such as figure 1 , 2 shown.
[0018] A multi-stage water purification device with a diamond electrocatalytic module, comprising a housing 5, characterized in that a first-stage filter 1 is installed in the housing 5, and a PP (polypropylene) melt spray filter element is used to pre-process the incoming water. Treatment can remove small particles, suspended solids, colloids and other substances in water, which is conducive to the full play of subsequent diamond electrocatalytic oxidation. The filter area and dirt holding capacity are large, the filter effect is good, the service life is long, and it can be cleaned many times. The secondary filter 2 uses a compressed activated carbon filter element to deeply remove the color, odor, and some residual chlorine in the water, effectively improving the taste of the water. The rod form and mesh const...

Abstract
The invention relates to a multistage water purifying device provided with a diamond electrocatalysis module, which comprises a shell (5) and a filter, and is characterized in that the filter comprises a first stage filter (1), a second stage filter (2), a diamond electrocatalysis module filter (3) and a fourth stage filter (4), wherein the input end of the first stage filter (1) is connected with a water inlet (6), while the output end of the first stage filter (1) is connected with the input end of the second stage filter (2) through a water pipe; the output end of the second stage filter (2) is connected with the input end of the diamond electrocatalysis module filter (3) through the water pipe; the output end of the diamond electrocatalysis module filter (3) is connected with the input end of the fourth stage filter (4) through the water pipe; and the output end of the fourth stage filter (4) is connected with a water outlet (7) through the water pipe. The multistage water purifying device achieves the chemical treatment of pollutants and the electrocatalysis inactivation of bacteria, is expected to avoid secondary pollution, has low energy consumption and long service life, has certain wastewater resistant concentration wave properties simultaneously, and is a train of thought for improving the prior common water purifying devices.
Description
technical field [0001] The invention relates to a combined water purification equipment, in particular to a multi-stage water purification equipment with a diamond electrocatalytic module. Background technique [0002] In recent years, water shortage and pollution problems have become increasingly serious, causing huge losses to social and economic development, and increasingly threatening the survival of human beings themselves. Countries around the world have invested a lot of manpower and material resources in research and governance. A series of wastewater treatment methods have emerged, among which the electrochemical method is favored by researchers in the field of water treatment due to its unique advantages. The reason is that the electrochemical method uses environmentally friendly and safe electrons as reactants, which is expected to avoid secondary pollution The equipment is relatively simple, easy to automatically control, and has a good treatment effect on refra...
