Abstract

A continuous rotating drum device of microelectrolyzing wastewater, belonging to a psychico-chemical treating device for degrading or removing the organic pollutant in wastewater. The main body of the device is a reacting pool and a continuous rotating drum placed horizontally in the pool, a baffle board is instilled in the continuous rotating drum, separating which into several parts, uniformly mixed iron scurf and activated charcoal is filled in the continuous rotating drum, the continuous rotating drum is anchored by adjustable speed motor. The rotary motion of the rotating drum makes the microelectrolyzing electrical field formed by the place of between the iron scurf and activated charcoal and iron charcoalf occur dural shift, which prevents the iron charcoal bed from clogging and lumping effectively. The device is characterized by the simple and rational structure, low producing cost, safe and simple operation and low running cost, which can be widely used to treat the non-degradable organic pollutant in wastewater and increase the wastewater biochemical property. The COD of textile dye waste clearance by using the device is high.

Description

1. Technical field [0001] The invention relates to a treatment device for industrial waste water and domestic sewage, especially a treatment device for colored and refractory biodegradable organic pollutants. 2. Background technology [0002] For the treatment of colored and refractory industrial wastewater, ordinary biological treatment often fails to achieve the expected results, and now it is common to increase pretreatment measures before biological treatment. Iron chip micro-electrolysis, also known as internal electrolysis, is an important pretreatment method in wastewater treatment. [0003] Iron scrap micro-electrolysis is a wastewater treatment method that integrates electrolysis, coagulation, electrocoagulation, adsorption and other physical and chemical effects. Through iron filings, a potential difference is formed between the high potential of iron in the aqueous solution and the low potential of carbon in it, producing countless tiny primary batteries, and the...
