Description

Technical Field

[0001] The technical field of the present invention is sewage treatment, specifically a sewage disposal method. Background Art

[0002] After sewage is collected and treated, sewage treatment is required. In the existing sewage disposal, sewage is generally mixed with clean stock solution and tap water, and then the treated distilled water and concentrated waste liquid are obtained. In this process, a large amount of clean stock solution is contained in the concentrated waste liquid. The existing technology can only directly fill the concentrated waste liquid into a ton barrel and cannot be reused; furthermore, the clean stock solution can only be used for sewage treatment once, resulting in high sewage treatment costs. Therefore, how to effectively utilize the clean stock solution in the concentrated waste liquid is a technical problem that urgently needs to be solved in sewage disposal. Summary of the Invention

[0003] In view of the above problems, the present invention provides a sewage disposal method, which enables the stock solution to perform repeated sewage treatment on sewage and reduces the cost of the clean stock solution.

[0004] A sewage disposal method, characterized in that: sewage, clean stock solution, and tap water are respectively connected to a sewage treatment device through pipelines. The sewage treatment device is also externally connected with a first intake pipe and a second intake pipe. The electrical components of the sewage treatment device are connected to a power line. The distilled water outlet of the sewage treatment device is externally connected to a distilled water bucket through a pipeline. The concentrated waste liquid outlet of the sewage treatment device has two branches. One branch is connected to a first one-way valve and then connected to a concentrated liquid ton barrel. The other branch is connected to a second one-way valve and then connected to a pneumatic pump and a pre-filter. The clean end of the pre-filter is connected to a sewage mixing bucket. The dirty end of the pre-filter is connected to the concentrated liquid ton barrel through a third one-way valve.

[0005] It is further characterized in that:

[0006] A lifting heat exchange component is arranged on the pipeline of the distilled water outlet of the sewage treatment device. The heat absorption end of the lifting heat exchange component is externally connected to a heat energy using device, and its energy can be reliably utilized;

[0007] A first flowmeter is connected to the distilled water outflow end of the lifting heat exchange component;

[0008] The sewage, clean stock solution, and tap water respectively flow into the sewage treatment device at a set flow rate. In the initial stage, the first one-way valve is closed and the second one-way valve is opened. When the flow rate of the first flowmeter is only 80% or less of the initial flow rate value, the first one-way valve is opened and the second one-way valve is closed. When the flow rate of the first flowmeter returns to 95% or more of the initial flow rate value, the first one-way valve and the second one-way valve are switched again, which enables the entire sewage treatment to operate in a cycle.

[0009] After adopting the present invention, the clean stock solution that has been treated by sewage is filtered through a pre-filter and then enters the sewage mixing tank for providing sewage, so that the clean stock solution is recycled multiple times for sewage treatment. It enables the stock solution to repeatedly treat sewage, reducing the cost of the clean stock solution. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE INVENTION

[0014] A sewage treatment method is as shown in Figure 1 : Sewage, clean stock solution, and tap water are respectively connected to the sewage treatment equipment 10 through pipelines. The sewage treatment equipment 10 is also externally connected with a first intake pipe 20 and a second intake pipe 30. The first intake pipe 20 is used to provide compressed gas, and the second intake pipe 30 is used to input defoamer. The electrical components of the sewage treatment equipment 10 are connected to the power line 40. The distilled water outlet of the sewage treatment equipment 10 is externally connected to the distilled water bucket 50 through a pipeline. There are two branches at the concentrated waste liquid outlet of the sewage treatment equipment 10. One branch is connected to the concentrated liquid ton bucket 70 after connecting the first one-way valve 60, and the other branch is connected to the pneumatic pump 1 and the pre-filter 2 after connecting the second one-way valve 80. The clean end of the pre-filter 2 is connected to the sewage mixing tank 90, and the dirty end of the pre-filter 2 is connected to the concentrated liquid ton bucket 70 after passing through the third one-way valve 90.

[0015] During specific implementation, a lifting heat exchange component 100 is arranged on the pipeline of the distilled water outlet of the sewage treatment equipment 10. The heat absorption end of the lifting heat exchange component 100 is externally connected to the heat energy using equipment, and its energy can be reliably utilized;

[0016] The distilled water outflow end of the lifting heat exchange component 100 is connected with a first flow meter 110;

[0017] Sewage, cleaning stock solution, and tap water flow into the sewage treatment device 10 at set flow rates respectively. In the initial stage, the first one-way valve 60 is closed and the second one-way valve 80 is open. When the flow rate of the first flowmeter 110 is only 80% or less of the initial flow rate value, the first one-way valve 60 opens and the second one-way valve 80 closes. When the flow rate of the first flowmeter 110 resumes to 95% or more of the initial flow rate value, the first one-way valve 60 and the second one-way valve 80 are switched again, which enables the entire sewage treatment to operate in a cycle.

[0018] Its working principle is as follows: The cleaned stock solution that has already undergone sewage treatment is filtered through a pre-filter and then enters the sewage mixing tank for providing sewage, so that the cleaned stock solution is recycled multiple times for sewage treatment. When the decontamination performance deteriorates, the corresponding amount of distilled water will decrease. Therefore, the second one-way valve is closed until the decontamination performance is restored, that is, after the amount of distilled water is restored, the switching operation of the first one-way valve and the second one-way valve is carried out again. This enables the stock solution to perform repeated sewage treatment on sewage, reducing the cost of the cleaned stock solution.
