Treatment system for bean vermicelli production wastewater

Abstract

The invention relates to a treatment system for bean vermicelli production wastewater, and belongs to the technical field of sewage treatment. The treatment system comprises a water inlet and a water outlet, wherein a first settling pond, an acidification adjustment pond, a lifting water pump, an anaerobic reactor, a second settling pond and an aerobic treatment pond are sequentially communicated between the water inlet and the water outlet through a pipeline; the first settling pond is used for the early-stage settling treatment of wastewater, the acidification adjustment pond is used for adjusting the water quality and quantity of high-concentration wastewater, and the anaerobic reactor is used for carrying out anaerobic fermentation, producing biogas and purifying the wastewater; the second settling pond is also provided with a branch loop reflowing to the anaerobic reactor, and the acidification adjustment pond also comprises a water quantity adjusting pond. According to the invention, a large amount of waste pollutants can be converted into a green energy namely biogas, thereby achieving a great promoting effect on the energy conservation and emissions reduction and benefit increasing of enterprises; through an anaerobic reaction, the removal rate of COD (chemical oxygen demand) is 90%, thereby ensuring the effect of wastewater treatment and up-to-standard release.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a treatment system for vermicelli production wastewater. Background technique [0002] During the vermicelli production process, a large amount of high-concentration organic wastewater is discharged, which contains a large amount of protein. Direct discharge not only wastes valuable protein, but also increases the cost of subsequent wastewater treatment. The vermicelli production factory must treat the production wastewater no matter from the consideration of enterprise benefit or social benefit. At present, the general vermicelli factory only makes a simple wastewater treatment process: that is, after the high-concentration wastewater first passes through the sedimentation tank to precipitate protein, the wastewater enters the aerobic tank for aeration and aerobic treatment, and then enters the secondary aerobic treatment to reduce the activity in the wastewater. The s...
