A fixed bed, treatment device and treatment method for in-situ treatment of organic wastewater

Abstract

The invention discloses an organic wastewater in situ treatment fixed bed, and a treatment apparatus and a treatment method thereof. The fixed bed comprises a fixed bed body, a fixed container is arranged in the fixed bed body, and the fixed container is filled with an iron-based sensitizing agent. The treatment apparatus comprises an apparatus body and a movable device arranged at the lower end of the apparatus body, and an aeration device, the fixed bed, a microwave cavity and a microwave generation device are arranged in the apparatus body, wherein the aeration device is connected with the bottom end of the fixed bed, the fixed bed is arranged in the microwave cavity, the microwave cavity is connected with the microwave generation device, and the fixed bed is connected with the outside of the apparatus body through a pipeline. Organic wastewater is pre-acidified, and pre-acidified organic wastewater enters the fixed bed of the wastewater treatment apparatus; and the pre-acidified organic wastewater is degraded and mineralized under the action of the iron-based sensitizing agent in the fixed bed and microwaves. The microwave iron-based sensitizing agent fixed bed realizes continuous, efficient and rapid treatment of wastewater; and the iron-based sensitizing agent is an environmentally friendly material, and causes no secondary pollution.

Description

technical field [0001] The invention belongs to the technical field of waste water treatment, and in particular relates to a fixed bed for in-situ treatment of organic waste water, a treatment device and a treatment method. Background technique [0002] Refractory organic wastewater can enter the environmental water body through leakage, wastewater discharge, and pesticide use. It is not easy to decompose or biodegrade, and it is easy to accumulate in organisms, water, and soil, thereby causing persistent pollution to the environment. Therefore, the effective treatment of refractory organic wastewater has important practical significance for protecting the environment, maintaining ecology and ensuring health. [0003] The treatment of refractory organic wastewater by biological methods generally requires a long hydraulic retention time and the treatment efficiency is extremely low. Generally speaking, refractory organic wastewater is mainly treated by advanced oxidation tec...

AI Technical Summary

Problems solved by technology

Generally speaking, refractory organic wastewater is mainly treated by advanced oxidation technology, which requires a large amount of oxidant consumption, resulting in higher costs

In addition, a lot of organic wastewater is produced as small streams of wastewater, which need to be collected and then processed. The collection process requires pipeline construction, which not only occupies land, but also may leak and cause soil and groundwater pollution.
