Embodiment Construction

[0024] Such as figure 1 with figure 2 As shown, the electrocoagulation device according to this embodiment includes an electrolytic cell 1, a plurality of drum electrodes 2 arranged horizontally in the electrolytic cell 1, the electrolytic cell 1 has a water inlet 6 at one end, and is opposite to the water inlet 6 The other end of has drain port 7.

[0025] In this example, the electrocoagulation equipment adopts 220-380V AC input, which is converted into DC after rectification, and then uses a pulse generator to form a pulse current. The power supply requires a panel display of current and voltage, and at the same time, independent stepless adjustment of current and voltage can be realized. The current adjustment range is 0-300A, and the voltage adjustment range is 0-500V. In order to delay the plate consumption speed, the power supply has a current timing commutation function, and the commutation time is adjustable. The distance between two adjacent drum electrodes is 80...

Abstract

The invention relates to a rotary-drum high-voltage pulse electric flocculation device which comprises an electrolytic bath and multiple rotary-drum electrodes, wherein the rotary-drum electrodes are arranged at intervals in the electrolytic bath; one end of the electrolytic bath is provided with a water inlet and the opposite end of the electrolytic bath is provided with a water outlet; a high-voltage pulse power supply is adopted for supplying power to the electric flocculation device, the electrodes are rotary-drum electrodes, and an electrode in each rotary-drum electrode is composed of an aluminum block, an iron block and a carbon block. The distance between every two adjacent rotary-drum electrodes is 500-1500mm. The electric flocculation device also comprises a deslagging plate, a sludge discharge bucket and an apparatus, wherein the deslagging plate is arranged at the upper part of the electrolytic bath and used for separating floating slag and foams from the surface of wastewater, the sludge discharge bucket is arranged at the bottom of the electrolytic bath and used for discharging sediments, and the apparatus is arranged at the upper part of an electrocoagulation bath and used for driving the rotary-drum electrodes. The electric flocculation device can be widely applied to the treatment of organic wastewater and electroplating wastewater, the pH value of treated sewage is 0-14, and acid waste or alkali waste with acid or alkaline concentration being less than 7% also can be effectively treated.

Description

technical field [0001] The invention relates to an electrocoagulation device, in particular to an electrocoagulation device for treating organic wastewater and electroplating wastewater, in particular to a wastewater treatment and purification device composed of an electrocoagulation sewage processor and a high-voltage pulse power supply. Background technique [0002] The difficult problem of sewage treatment technology is the treatment of high-concentration refractory organic wastewater and electroplating wastewater. This type of wastewater is mainly wastewater produced in the production processes of dyes, pesticides, biomedicine, chemicals and electroplating. The common feature of this type of wastewater is that it contains refractory organic matter or heavy metals. The pollutants in the wastewater have complex composition, many types, high concentrations, high toxicity, and high salinity. In addition, the electroplating wastewater contains high heavy metals and a relative...
