Description

Technical Field

[0001] This utility model relates to the technical field of landfill leachate treatment devices, and in particular to a landfill leachate treatment device. Background Technology

[0002] Existing patents, when treating wastewater with coagulants, use a large sedimentation tank for treatment. This requires a large number of motor-driven stirring devices for mixing and agitation, and regular shutdowns are necessary for cleaning and maintenance of the sedimentation tank. This results in high noise and power consumption, and wastewater accumulation during shutdowns affects work efficiency.

[0003] This proposal is put forward in order to improve and optimize the above-mentioned problems or shortcomings. Utility Model Content

[0004] A landfill leachate treatment device includes a processor body, within which are arranged a plurality of arrayed, separate wastewater flocculation units. A coagulant main pipe, a wastewater main pipe, a treated water main drain pipe, and a flocculant main drain pipe are externally connected to the processor body. Each separate wastewater flocculation unit is respectively equipped with an inner wastewater branch pipe, a sleeve branch pipe, a treated water branch drain pipe, and a flocculant branch drain pipe base. The sleeve branch pipe is connected to the coagulant main pipe via a pipe, and the inner wastewater branch pipe is connected to the coagulant main pipe via a pipe. The main wastewater discharge pipe is connected to the wastewater main pipe, and the main treated water discharge pipe is connected to the main treated water branch pipe through a pipe. The main flocculation discharge pipe is connected to the bottom shell of the flocculation branch pipe through a pipe. The coagulant and the wastewater from the landfill filtrate simultaneously enter the split-type wastewater flocculation unit for mixing and flocculation. Then, the liquid part passes through the filter element in the split-type wastewater flocculation unit and flows through the main treated water branch pipe to the main treated water discharge pipe for discharge. The flocculated material flows through the bottom shell of the flocculation branch pipe to the main flocculation discharge pipe for discharge.

[0005] Preferably, the split-type waste liquid flocculation unit includes a cylindrical tank, in which a funnel-shaped filter core is embedded, and a flocculation branch pipe bottom shell is threadedly sealed to the bottom of the tank, wherein the upper end of the flocculation branch pipe bottom shell is interference-fitted with the middle hole of the funnel-shaped filter core.

[0006] Preferably, the inner branch pipe of the waste liquid and the outer branch pipe are coaxially overlapped, and the inner branch pipe of the waste liquid is provided with through drainage holes at annular intervals in the overlapping part, and the waste liquid inner branch pipe and the outer branch pipe are mixed and flocculated in the overlapping section.

[0007] Preferably, a spiral guide vane is also fixedly installed inside the sleeve branch pipe. The spiral guide vane does not contact the waste liquid inner branch pipe. After the sewage in the waste liquid inner branch pipe is discharged through the drain hole, it comes into contact with and mixes with the coagulant flowing in the sleeve branch pipe. The mixing and contact effect can be improved under the action of the spiral guide vane.

[0008] Preferably, the upper end face of the funnel-shaped filter core is a conical inclined surface, which facilitates the introduction of flocculated material into the bottom shell of the flocculated material branch pipe.

[0009] The advantages and positive effects of this utility model are:

[0010] 1. Compared with the traditional large-scale mixing tank design, this application adopts a split-integration design to change centralized treatment into array-type distributed treatment and then convergence. This allows for the disassembly, replacement and cleaning of some units in batches during the treatment process, enabling the device to continuously treat sewage without stopping, which is more efficient and convenient.
