An iron-carbon reactor equipment and treatment process for treating high-concentration organic wastewater

Abstract

The invention relates to an iron carbon reactor facility and technique for treating high-concentration organic wastewater. The facility comprises a tank body, microporous aeration disks, a vertical steel tube, I-bar cross beams, a pore plate and a wave cover plate, wherein the bottom in the tank body is provided with the micropore aeration disks; the I-bar cross beams are installed in the tank body, and connected and supported through the vertical steel tubes; the pore plate is arranged on the I-bar cross beams; the top of the tank body is provided with the wave cover plate; an annular groove is arranged around the wave cover plate; the lower side of the outer wall of the tank body is provided with a water inlet, and the upper side is provided with a water outlet; and the outer wall of the tank body is provided with a ladder. According to the technique, wastewater is subjected to aeration and iron carbon reaction to obtain the clean water. The facility is simple in structure; and the treatment technique is simple and easy to implement, and has the advantages of high reaction efficiency and favorable wastewater treatment effect.

Description

Technical field [0001] The invention belongs to the technical field of wastewater treatment, and specifically relates to an iron-carbon reactor equipment and a treatment process for treating high-concentration organic wastewater. Background technique [0002] Environmental pollution is an important problem in today's world. A large amount of high-concentration organic wastewater with high chroma and poor biodegradability is discharged in the production fields of chemicals, pesticides, dyes, and pharmaceuticals. High-concentration organic wastewater is an important factor leading to environmental pollution, which seriously affects people's living environment. In the prior art, as a commonly used high-concentration organic wastewater treatment device, the iron bed has problems such as low efficiency, slow reaction speed, easy compaction of the bed body, short circuit and dead zone, and high labor intensity for iron filings. During operation, filler passivation, compaction, and “co...

AI Technical Summary

Problems solved by technology

In the prior art, as a commonly used high-concentration organic wastewater treatment device, the iron bed has problems such as low efficiency, slow reaction speed, easy hardening of the bed body, resulting in short circuits and dead zones, and high labor intensity for iron scrap supplementation. During operation, filler passivation, compaction, and effluent "color return" often occur. Using a fluidized bed device can better solve the problem of compaction of iron bed fillers, but higher investment costs, operating costs and operational management requirements make The application of this device is limited
