Embodiment 1

[0009] The daily discharge of spinning oil wastewater from the simulated enterprise is about 35m 3 / d, considering a certain margin, therefore, the design wastewater treatment scale is 48m 3 / d.

[0010] The oily waste water produced in the production workshop of this enterprise is used in 1m 3 The oily waste water in the barrel is transported by a forklift and poured into the sump; the sump is agitated by air to ensure that the oily waste water in the sump can be fully mixed, and then it is sent into the grease trap by the lifting pump and scraped The oiler separates and collects the floating oil floating on the water surface; the waste water after oil separation flows into the Fenton reaction tank, and at the same time, the hydrogen peroxide and ferrous sulfate are quantitatively fed by the metering pump, and react under the mixing action of the agitator, and the Fenton reaction destroys the emulsifier The charge balance of the organic molecules makes the organic molecules...

Abstract

The invention relates to a sewage treatment device, and discloses a high-concentration spinning oil wastewater pretreatment system. The high-concentration spinning oil wastewater pretreatment system comprises successively connected a water collection pool, an oil separation pool, a Fenton reaction pool, a neutralization pool, a sedimentation pool A, a coagulation pool, a sedimentation pool B and a clean water pool. According to the high-concentration spinning oil wastewater pretreatment system, oil contamination and organic matters in wastewater can be greatly reduced, the pretreatment COD (chemical oxygen demand) removal rate can reach above 70%, and outlet water has little effects on the comprehensive sewage treatment system.

Description

technical field [0001] The invention relates to a sewage treatment device. Background technique [0002] The same polyester plant can produce 300,000 tons of fiber-grade polyester melt and chips per year, and the melt direct spinning filament device can produce 300,000 tons of polyester filaments per year. For polyester production equipment, a comprehensive sewage treatment plant will generally be built, using UASB + biological contact oxidation tank + ultrafiltration + reverse osmosis process to treat and reuse the effluent. Spinning oil is used in the spinning process and waste water is generated, and the oil waste is discharged intermittently. Although the amount of oil wastewater is small, its COD concentration is extremely high. Contents of the invention [0003] The invention aims to provide a high-concentration spinning finish wastewater pretreatment system capable of reducing oil pollution and organic matters in the wastewater. [0004] The high-concentration sp...
