Abstract

The invention relates to the technical field of printing and dyeing wastewater treatment, and discloses a printing and dyeing wastewater treatment system and method. The treatment system includes a micro-electrolysis reactor for treating printing and dyeing wastewater. The micro-electrolysis reactor includes a tank, a top-down sewage inlet pipe for introducing printing and dyeing wastewater into the tank, and several The micro-electrolysis treatment component for electrolytic treatment and several first gas distribution components that allow the oxidizing gas to pass through the micro-electrolysis treatment component uniformly; the treatment method is: install a liquid density sensor in the collection tank, and set the standard value of the density of the sedimented flocs , detect the liquid density data, compare it with the standard value of the sediment density, start the sewage discharge component to discharge the sewage according to the comparison result, and distribute the oxidizing gas injected into the tank through the first gas distribution component, so that the oxidizing gas can be distributed evenly Through the micro-electrolysis treatment component, while improving the aeration effect, it can also avoid the problem that sediment flocs are easy to accumulate in the micro-electrolysis treatment component.

Description

technical field

[0001] The invention relates to the technical field of printing and dyeing wastewater treatment, in particular to a printing and dyeing wastewater treatment system and method. Background technique

[0002] With the continuous deepening of the industrialization process, global pollution is increasingly destroying the ecological balance formed by the earth's biosphere for hundreds of millions of years, and posing a threat to the living environment of human beings. According to the statistics and investigation of the current situation of water environment pollution in my country by the State Environmental Protection Administration, my country's rivers, lakes and coastal watersheds have generally been polluted to varying degrees, and the overall trend is aggravating. The main factors causing the aggravation of pollution are industrial wastewater and domestic sewage. The textile printing and dyeing industry discharges a large amount of waste water and waste residue...
