Problems solved by technology

Static sedimentation and oil separation method has the advantages of no need to add chemicals and low cost, but has the disadvantage of poor separation effect, and it is still very difficult to treat wastewater after oil separation; dissolved air flotation method is more suitable for the treatment of low concentration oily wastewater. The effect of high concentration oily wastewater is poor

Embodiment Construction

[0019] Attached below figure 1 And examples further illustrate the present invention.

[0020] Taking the sewage treatment process in the production plant of a chemical fiber oil production enterprise as an example, during the sewage treatment process in the production plant of the chemical fiber oil production enterprise, the amount of chemical fiber oil agent wastewater produced is about 2 tons per day, and the highest concentration of COD can reach 1×10 6 mg / L. In addition, the toilets and restaurants in the factory will produce about 7 tons of domestic sewage per day, with a maximum concentration of COD of 500 mg / L; the production of washing water in the workshop is about 2 tons per day, with a maximum concentration of COD of 1700 mg / L ; The amount of effluent in the oily road path generated by rain in the finished product loading and unloading area and the truck parking lot is about 9 tons per day.

Abstract

The invention discloses a method for comprehensively treating sewage of chemical fiber oiling agents in production plants. The method mainly includes the following steps: mineral oil is recovered from the chemical fiber oiling agents through acidification; the acidified lower clear liquid is performed with a Fenton reaction and then enters a middle water tank to be homogenized with washing water in a workshop and run-off rain water of oiliness paths; suspended materials and small elaioplast in the homogenized sewage are removed through an air floating pool; the water discharged from the air floating pool and sanitary sewage together enter a comprehensive adjusting tank to be treated by an anaerobic baffle pool, an aerobiotic pool and a settling pool, and then outlet water can meet the B-level wastewater quality standards for discharge to municipal sewers (CJ3082-2010). The method for comprehensively treating sewage of chemical fiber oiling agents is convenient to manage and maintain, capable of adapting to large water quality fluctuation, stable and reliable in treating effect and moderate in operation cost.

Description

technical field [0001] The invention relates to a comprehensive treatment method for sewage, in particular to a comprehensive treatment method for sewage in chemical fiber oil agent production plants. Background technique [0002] Chemical fiber oil is one of the necessary auxiliary agents in the manufacture of synthetic fibers and their spinning process. Its function is to make the fibers have good smoothness, bunching and antistatic properties, and meet the requirements of fiber processing. With the development of the synthetic fiber industry, the production of synthetic fibers has entered the stage of multi-variety, small-batch and high-speed, requiring a large number of new oil agents to cooperate with it. In 2011, the annual output of synthetic fibers in my country has reached more than 30 million tons, and the annual oil consumption is about 300,000 tons, including polyester oil, polypropylene oil, nylon and acrylic oil, and other oils. Chemical fiber oils generally c...
