Problems solved by technology

However, the reduction of perchlorate by the sulfur autotrophic process is a process of acid production, so it is necessary to add alkalinity in the process to achieve the acid-base balance in the system to ensure the activity of microorganisms, which leads to an increase in process costs

Embodiment Construction

[0043] In order to make the technical solution and process advantages of the present invention clearer, the exemplary implementation of the present invention will be further described in detail below by changing different parameters and in conjunction with the accompanying drawings, and the indicators of influent and effluent water will be analyzed. Apparently, the described embodiments are only some of the embodiments of the present invention, and are not exhaustive of all the embodiments.

[0044] see figure 1, is a schematic structural diagram of the ABR system provided by the embodiment of the present invention. The ABR system includes a reactor, and the reactor is provided with a waste water inlet and a water outlet. The industrial waste water to be treated enters the reactor from the water inlet, and flows out from the water outlet after biodegradation. A plurality of baffles are vertically arranged in the reactor, and the plurality of baffles divide the reactor into a ...

Abstract

The invention discloses an ABR (anaerobic baffled reactor) system to degrade high-concentration perchlorate wastewater, comprising: a reactor; and a plurality of baffles vertically arranged in the reactor. The baffles divide the reactor into multiple serial cells; each cell includes a lower flow chamber and an upper flow chamber; the cells are divided into a heterotrophic zone and an autotrophic zone along a flow propelling direction; the upper flow chambers of the heterotrophic zone are each filled with a sludge bed, the lower flow chambers are each provided with an inflow pipe, and a segmented inflow structure is formed; the upper flow chambers of the autotrophic zone are each filled with sulfur particles and quartz sand to form a double-layer filler. The ABR system herein has significant advantage in the treatment of perchlorate wastewater with inharmonious carbon-chlorine ratio.

Description

technical field [0001] The invention belongs to the field of biological treatment of industrial wastewater, and in particular relates to an ABR system for degrading high-concentration perchlorate wastewater and a control method for degrading high-concentration perchlorate wastewater based on the ABR system. Background technique [0002] Perchlorate is a special chemical substance, which is widely used in aerospace and munitions industry and other fields. In recent years, with the rapid development of my country's aerospace industry and industry, in the process of industrial production, high-concentration perchlorate wastewater will be produced and discharged into the water environment. Therefore, it is imminent to efficiently remove perchlorate in water. Perchlorate has the characteristics of persistence, strong stability and high solubility in natural water bodies. When a small amount of perchlorate enters the human body, it can inhibit the absorption of iodide ions by the...
