System for treating high-concentration organophosphorus wastewater and treatment process thereof

Abstract

The invention provides a system for treating high-concentration organophosphorus wastewater and a treatment process thereof. The system comprises a treatment tank, supporting legs, a tank cover, a mixing motor, a coupling, a mechanical valve, a wastewater introduction pipe, a flow guide pipe, a distillation tower, a discharge pipe and a drain valve, and the supporting legs are in bolted connection with four corners of the bottom of the treatment tank. According to the invention, iron and carbon form countless microbattery systems in wastewater, the wastewater is electrolyzed, part of organic matters are oxidized, a large amount of ferrous iron is generated through anodic reaction, enters the wastewater and is further oxidized into ferric iron, and a flocculating agent with relatively high adsorption and flocculation activity is formed; and a large amount of nascent [H] and [O] are generated through cathode reaction, and under the slightly acidic condition, the active ingredients can be subjected to oxidation-reduction reaction with ethyl alcohol, chloroethane and ethyl methyl hypophosphite in the wastewater, so that organic macromolecules are subjected to chain scission degradation, and the pH value of the wastewater is also increased.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a system and a treatment process for treating high-concentration organic phosphorus wastewater. Background technique [0002] Exceeding the standard of phosphorus in water will accelerate the eutrophication of the water body. This phenomenon is more serious in our country and has brought great harm to industry, aquaculture, agriculture and tourism. The increase in the concentration of phosphorus and other nutrients is the cause of algae Therefore, how to effectively reduce the concentration of phosphorus in sewage is of great significance to eliminate pollution and protect the environment. [0003] At present, domestic and foreign wastewater phosphorus removal technologies mainly include biological methods and chemical methods: biological methods such as A / O, A2 / O.UCT processes are mainly suitable for treating low-concentration and organic phosphorus-containi...
