Fenton treatment device and method for bamboo product wastewater

Abstract

The invention discloses a Fenton treatment device and method for bamboo-product wastewater, and belongs to the field of the treatment of bamboo-product wastewater. When a wastewater treatment method in the prior art is used for treating the bamboo-product wastewater, the water quality of yielding water is poor; the efficiency is low. The Fenton treatment device comprises a Fenton oxidation device, an up-flow anaerobic sludge bed reactor and a two-stage A / O (Anoxic / Oxic) system, wherein a gas floater for removing a SS (Suspended Solid) and insoluble COD (Chemical Oxygen Demand) is arranged between the up-flow anaerobic sludge bed reactor and the two-stage A / O system; the bamboo-product wastewater flows through the Fenton oxidation device, the up-flow anaerobic sludge bed reactor, the gas floater and the two-stage A / O system in sequence through pipelines or ditches. The Fenton treatment device adopts a triple treatment device, is used for solving the treatment problem of the bamboo-product wastewater, is reasonable in structure, reasonable in procedure and good in treatment effects, can be used for effectively solving the treatment problem of the bamboo-product wastewater, moreover, is low in investment cost, and is economical and practical.

Description

technical field [0001] The invention relates to a bamboo product wastewater Fenton treatment device and method, belonging to the field of bamboo product wastewater treatment. Background technique [0002] Bamboo product processing wastewater belongs to high-concentration organic wastewater. If it is discharged directly, it will pollute the surrounding environment. Therefore, the discharged wastewater must be treated. High-concentration organic wastewater mainly has the following characteristics: First, the concentration of organic matter is high. COD is generally above 8000 (mg / L), and some even as high as tens of thousands or even hundreds of thousands (mg / L). Relatively speaking, BOD is low, and the ratio of BOD to COD in many wastewaters is less than 0-3. Second, the composition is complex. The organic matter in wastewater containing toxic substances is mostly aromatic compounds and heterocyclic compounds, and also contains sulfides, nitrides, heavy metals and toxic org...

AI Technical Summary

Problems solved by technology

Second, the composition is complex

Third, high chroma and peculiar smell

[0005] The first is aerobic hazards: due to biodegradation, high-concentration organic wastewater will make the receiving water body anoxic or even anaerobic, and most aquatic organisms will die, resulting in stench, deteriorating water quality and environment

[0006] The second is sensory pollution: high-concentration organic wastewater not only makes the water lose its use value, but also seriously affects the normal life of people near the water.

[0007] The third is toxicity hazards: ultra-high concentration organic wastewater contains a large amount of toxic organic substances, which will continue to accumulate and store in natural environments such as water bodies and soils, and finally enter the human body, endangering human health

However, direct use of the existing technology to treat bamboo product wastewater has poor effluent quality, low efficiency, and weak load-bearing capacity.
