Water purification device

Abstract

The invention provides a water purification device. The water purification device comprises a main engine and an electrode which are electrically connected with each other. The main engine comprises a chassis and a circuit board fixed inside the chassis, wherein an AC power socket and an output interface are arranged outside the chassis; the circuit board is electrically connected with the AC power socket and outputs current through the output interface; the electrode comprises pole pieces and a junction box which are fixedly connected with each other; the appearance of the pole pieces is a rectangular plate; and the main engine can output fixed current or current with change frequency. According to the multiple pole pieces and the current output with change frequency of the main engine, ammonia nitrogen in water can be effectively reduced or eliminated, components of nitrate and nitrite can be reduced, the numerical value of chemical oxygen demand COD is reduced, and bacteria in the water are killed. Moreover, the structure in the invention can produce lots of tiny bubbles, has a certain flocculation effect and can purify the water quality, and when pollutants are continuously produced, a dynamic balance of the water quality can be achieved by virtue of enough treatment speed, so that stable water quality is guaranteed.

Description

technical field [0001] The invention relates to the technical field of water purification, in particular to a water purification device. Background technique [0002] In recent years, with the improvement of people's living standards, more and more families raise ornamental fish and other aquatic animals and plants, but many people give up halfway. The main reason is that it is too difficult to keep the water fresh for a long time. At present, various electrolytic water treatment When the device is doing water treatment, due to design problems, the treatment efficiency will be lower and lower, the content of certain organic substances will be higher and higher, and the water body will become more acidic or alkaline, which cannot completely solve the problem of water purification, resulting in water pollution. The mortality of animals and plants is high, and the water body can only be discharged if it can no longer be used. Contents of the invention [0003] In order to so...
