Problems solved by technology

[0005] Therefore, the existing groundwater treatment process is single, and when there are many kinds of pollutants, the operation and maintenance costs are high, and the physical and chemical methods often cause certain limitations in practical application when removing pollutants: the system produces Salt wastewater is difficult to dispose of, and cannot meet the process conditions, kinetics and thermodynamics of catalytic reduction, etc.

Embodiment 1

[0052] figure 1 For the sewage treatment system of the present invention, such as figure 1 As shown, the anaerobic bioreactor provided by the present invention includes: a reactor shell 1, an adsorption biological carrier, microorganisms, a sewage inlet 3, and a clean water outlet 4; the reactor housing 1 is filled with an adsorption biological carrier and microorganisms , and the sewage inlet 3 communicates with the upper part of the reactor shell 1, and the purified water outlet 4 communicates with the lower part of the reactor shell 1.

[0053] The anaerobic bioreactor of the present invention, combined with adsorptive biological carriers and microorganisms, for example, granular activated carbon will be transformed into biologically activated carbon 2, which can not only be used as a support material for biofilm growth, but also can simultaneously realize adsorption and biodegradation, and improve the treatment efficiency. capacity for pollutants.

[0054] The present in...

Embodiment 2

[0083] figure 2 It is a flow chart of the sewage treatment method of the present invention, as figure 2 As shown, the method provided by the present invention based on the realization of the above-mentioned sewage treatment system comprises the following steps:

[0084] Utilize the sewage inlet pump to transport the sewage in the sewage pool 15 to the anaerobic bioreactor;

[0085] Use the microorganisms in the anaerobic bioreactor to decompose the pollutants in the sewage, and use the adsorption biological carrier to absorb the pollutants in the sewage and the decomposition products after the decomposition of the pollutants to obtain clean water;

[0086] The clean water is discharged through the clean water discharge line 16 .

[0087] The anaerobic bioreactor of the present invention combines adsorption biological carrier and microorganisms, can realize adsorption and biodegradation at the same time, and improves the ability to treat various pollutants.

[0088] The pr...

Embodiment 3

[0098] Treat artificially simulated groundwater

[0099] Prepare fresh artificially simulated groundwater and purify it with nitrogen for about 30 minutes until the dissolved oxygen concentration in the artificially simulated groundwater drops to 1.0 mg / L to form strict anaerobic conditions to avoid oxidation of ferrous ions. Granular activated carbon was rinsed twice with deionized water and dried in an overnight oven at 70 °C before use. The operating temperature of the bioreactor is controlled between 25-35°C. Before the official operation, the mixed sludge from the nitrate anaerobic biological reaction tank and the sulfate anaerobic biological reaction tank collected from the sewage treatment plant will be used for the bioreactor. Perform sludge inoculation.

[0100] The artificially simulated groundwater is treated by using the sewage treatment system of Embodiment 1 and the sewage treatment method of Embodiment 1. In this example, the bioreactor is composed of a transp...

Abstract

The invention provides an anaerobic bioreactor, a sewage treatment system and a sewage treatment method. The anaerobic bioreactor comprises a reactor shell (1), an adsorptive biological carrier, microorganisms, a sewage inlet (3) and a purified water outlet (4), wherein the reactor shell (1) is filled with adsorptive biological carriers and microorganisms, the sewage inlet (3) communicates with the upper part of the reactor shell (1), and the purified water outlet (4) communicates with the lower part of the reactor shell (1). The anaerobic bioreactor disclosed by the invention is combined withan adsorptive biological carrier and microorganisms, so that an adsorption effect and biodegradation can be realized at the same time, and the capability of treating various pollutants is improved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an anaerobic bioreactor, a sewage treatment system and a sewage treatment method. Background technique [0002] With the growth of population and the rapid development of social economy, the demand for water resources has also increased significantly. Groundwater is widely used for various purposes and is the main source of drinking water in many countries and regions. With the development of my country's industry and the gradual increase in the amount of agrochemical synthetics, drinking water sources are polluted to varying degrees, and it is developing. The general pollution indicators refer to organic matter, such as ammonia nitrogen and COD exceeding the standard, etc., but drinking water indicators Common pollutants also include various anions (sulfate, nitrate, etc.) and heavy metals (arsenic, iron, etc.). [0003] The conventional water treatment process is the ...
