Description

Technical Field

[0001] This utility model relates to the technical field of waste treatment systems, and in particular to a biochemical emergency aeration system for treating landfill leachate. Background Technology

[0002] The current mainstream process for treating landfill leachate is "pretreatment + anaerobic system + biochemical system + ultrafiltration + nanofiltration + reverse osmosis". The final water produced by the treatment system can be used as makeup water for the cooling circulation tower of the incinerator, and the concentrated water can be used as a supplement for the semi-dry lime slurry in the flue gas treatment process.

[0003] As one of the most important processes in leachate treatment, the biological treatment system can further remove COD from anaerobic permeate while also achieving high removal rates for elements such as nitrogen and phosphorus. The biological treatment system primarily utilizes the metabolic activity of microorganisms to degrade organic matter, nitrogen, phosphorus, and other pollutants in wastewater, converting them into harmless or less harmful substances. Since microbial metabolism requires dissolved oxygen, the aeration system's role is to oxygenate the biological treatment tank, providing sufficient oxygen for microbial activity.

[0004] Currently, the mainstream aeration method in landfill leachate treatment processes is jet aeration. Water is pumped from the biological treatment tank and pressurized to the jet aerator by a jet pump. After being mixed evenly with the air delivered by the blower, the mixture is jetted out in all directions. This not only improves oxygen utilization but also fully agitates the aerobic sludge deposited in the biological treatment tank.

[0005] However, if there are many impurities in the biological treatment tank, the aeration heads are easily clogged, resulting in poor aeration effect. During the summer flood season, when the sludge load of the biological treatment system is high, the biological treatment system is prone to water quality deterioration and reduced treatment capacity, resulting in insufficient storage capacity and adverse events such as the overflow of the collection tank. Utility Model Content

[0006] The purpose of this invention is to provide a biochemical emergency aeration system for landfill leachate treatment, so as to alleviate the technical problems of low oxygen utilization and inconvenient installation caused by numerous pipelines in the existing technology.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] In a first aspect, this utility model provides a biochemical emergency aeration system for landfill leachate treatment, including a blower, a main pipeline and multiple sets of aeration components, wherein the blower is connected to the main pipeline;

[0009] Multiple sets of the aeration components are spaced apart along the extension direction of the main pipeline, and each set of the aeration components includes a rotary aerator.

[0010] Furthermore, the aeration assembly also includes an air inlet branch pipe and a regulating ball valve, one end of which is connected to the main pipeline and the other end of which is connected to the rotary aerator;

[0011] The regulating ball valve is connected to the intake branch pipe.

[0012] Furthermore, the rotary aerator includes a connector and a rotary aerator head, the rotary aerator head being connected to the air inlet branch pipe via the connector.

[0013] Furthermore, the rotary aerator head has an inverted umbrella-shaped structure, with a swirling ring inside, and a dynamic core is installed at the lower part of the rotary aerator head.

[0014] The outer circumferential surface of the rotary aerator head is provided with multiple layers of inclined inverted teeth.

[0015] Furthermore, the landfill leachate treatment biochemical emergency aeration system also includes a monitoring component, which is connected to the main pipeline.

[0016] Furthermore, the monitoring component includes a pressure gauge connected to the main pipeline.

[0017] Furthermore, the monitoring component also includes an airflow meter, which is connected to the main pipeline.

[0020] Furthermore, the landfill leachate treatment biochemical emergency aeration system also includes a control component, which is electrically connected to the blower.

[0021] This utility model can achieve the following beneficial effects:

The main pipeline is preferably a bent semi-circular structure. Multiple sets of aeration components are spaced apart along the extension direction of the main pipeline. In use, the blower blows air into the main pipeline, which then directs the air to each aeration component. Due to the bent shape of the main pipeline, the multiple aeration components connected to it can achieve aeration within a certain enclosed area, effectively overcoming the problem of low oxygen utilization.
