Abstract

The invention provides an organosilicone wastewater treatment system and a treatment method thereof. The system comprises a wastewater pretreatment system and a wastewater treatment system connected in series, wherein the wastewater treatment system comprises a neutralization adjustment unit, an inorganic ion precipitation unit, a heating unit, a catalytic wet oxidation unit, a gas-water separation unit, and a biochemical treatment unit which are connected in sequence. The treatment method comprises pre-treating organosilicone wastewater, and sequentially performing neutralization adjustment,inorganic ion precipitation, heating, catalytic wet oxidation, gas-water separation and biochemical treatment on the pre-treated organosilicone wastewater, and obtaining standard wastewater. The system provided by the invention has simple process flow and good compatibility, and avoids the use of multi-stage oxidation, and can be continuously operated, and can greatly reduce the area occupied by the equipment and effectively treat a variety of silicone resin and silicone rubber wastewater with complex composition, various types and poor biodegradability in the same system.

Description

technical field [0001] The invention belongs to the field of waste water treatment, and in particular relates to an organosilicon waste water treatment system and a treatment method thereof. Background technique [0002] Silicone materials have excellent properties such as high and low temperature resistance, weather resistance, electrical insulation, radiation resistance, flame retardant, corrosion resistance, physiological inertness and biocompatibility, so they are widely used in aerospace, national defense, electronic appliances, petroleum, light industry , Construction, metallurgy, machinery, office equipment, transportation, food processing, daily chemical industry and other fields, known as "industrial monosodium glutamate", its products can be divided into silicone oil, silicone rubber, silicone resin and silane coupling agent four category. [0003] At present, silicone resin is mainly produced by siloxane hydrolysis in China, and a large amount of wastewater conta...
