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 comprises a micro-electrolysis reactor for treating the printing and dyeing wastewater, wherein the micro-electrolysis reactor comprises a tank body, a sewage inlet pipe used for guiding printing and dyeing wastewater into the tank body from top to bottom, a plurality of micro-electrolysis treatment assemblies used for carrying out an electrolysis treatment on the printing and dyeing wastewater, and a plurality of first gas distribution assemblies used for enabling oxidizing gas to uniformly pass through the micro-electrolysis treatment assemblies; the treatment method comprises the following steps: arranging a liquid density sensor in a collecting tank; setting a flocculate density standard value; detecting liquid density data, comparing the liquid density with the flocculate density standard value; and according to a comparison result, starting a pollution discharge assembly to discharge pollutants. The first gas distribution assemblies can be used for distributing oxidation gas injected into thetank body, the oxidation gas can uniformly pass through the micro-electrolysis treatment assemblies, the aeration effect is improved, and meanwhile, the problem that flocculate is easy to accumulatein the micro-electrolysis treatment assemblies can be avoided.

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...
