[0002] Coking ammonia stripping wastewater treatment equipment is a system designed to treat wastewater containing toxic and harmful substances such as phenol, cyanide, and ammonia nitrogen generated during the coking process. Its treatment process typically includes four stages: pretreatment, biochemical treatment, advanced treatment, and sludge treatment.

[0003] However, existing coking ammonia stripping wastewater treatment equipment often lacks the functions of oil removal and cooling, which is not conducive to the subsequent treatment of coking ammonia stripping wastewater.

[0004] Therefore, it is necessary to provide a coking ammonia stripping wastewater treatment device to solve the above-mentioned technical problems. Utility Model Content

[0005] To address the technical problem that existing coking ammonia stripping wastewater treatment devices often lack oil removal and cooling functions for the wastewater, this utility model provides a coking ammonia stripping wastewater treatment device.

[0006] The coking ammonia-removing wastewater treatment device provided by this utility model includes: an equalization tank; a cooling water tank fixedly installed at the bottom of the equalization tank; a frame fixedly installed at the top of the equalization tank; an aerobic tank located on one side of the equalization tank; an anaerobic tank located on one side of the aerobic tank; an aeration mechanism installed on the aerobic tank for aerating the wastewater during the equalization tank; a circulating cooling mechanism installed on the equalization tank for cooling the coking ammonia-removing wastewater; and an oil removal mechanism installed on the frame for removing oil from the coking ammonia-removing wastewater.

[0007] Preferably, a first wastewater pump is installed on the equalization tank, and a first wastewater pipe is installed at the outlet of the first wastewater pump. The first wastewater pipe is connected to the aerobic tank. A second wastewater pump is installed on one side of the aerobic tank, and a second wastewater pipe is installed at the outlet of the second wastewater pump. The second wastewater pipe is connected to the anaerobic tank.

[0008] Preferably, the anaerobic tank is equipped with a drain pipe, and the drain pipe is equipped with a drain valve.

[0009] Preferably, the aeration mechanism includes: a pipe array fixedly installed on the inner wall of the top of the aerobic tank; an aeration pipe provided on the pipe array and having aeration holes; an air pump fixedly installed on the top of the aerobic tank; an air inlet pipe installed on the air pump and connected to the pipe array; and an exhaust pipe provided on the aerobic tank.

[0010] Preferably, the circulating cooling mechanism includes: a spiral heat-conducting pipe disposed on the inner wall of the regulating pool; a circulating pump disposed on the inner wall of the cooling water tank, the outlet end of the circulating pump being connected to the spiral heat-conducting pipe; a chiller fixedly installed on one side of the regulating pool and connected to the spiral heat-conducting pipe; a return water pipe disposed at the bottom of the chiller and extending into the interior of the cooling water tank; and a water temperature sensor disposed on the inner wall of the cooling water tank.

[0011] Preferably, the oil removal mechanism includes: an electric cylinder fixedly mounted on the frame; a rectangular plate fixedly mounted on the output rod of the electric cylinder; a density sensor and an oil pump mounted on the rectangular plate; and an oil guide pipe disposed at the oil outlet end of the oil pump.

[0012] Preferably, the cooling water tank has a water inlet, the water inlet is provided with a sealing cap, and a controller is provided on one side of the frame.

[0013] Compared with related technologies, the coking ammonia stripping wastewater treatment device provided by this utility model has the following beneficial effects: This invention provides a coking ammonia stripping wastewater treatment device. An equalization tank regulates the flow rate and quality of the wastewater, stabilizing the flow and pollutant concentration to ensure uniform and stable subsequent treatment processes. An aerobic tank utilizes aerobic bacteria to further degrade organic matter and ammonia nitrogen, while an anaerobic tank treats the wastewater anaerobicly, decomposing some organic matter into methane under anaerobic conditions. Carbon dioxide and other substances are used to reduce the COD of wastewater and improve its biodegradability. An aeration system treats the wastewater in the aerobic tank with aeration, a circulating cooling system cools the wastewater in the equalization tank, and an oil removal system removes oil from the wastewater in the equalization tank. A first wastewater pump pumps wastewater from the equalization tank and injects it into the aerobic tank through a first wastewater pipe. A second wastewater pump pumps wastewater from the aerobic tank and injects it into the anaerobic tank through a second wastewater pipe. Wastewater is discharged once through a drain pipe and drain valve. In subsequent treatment, air is injected into the pipe array via an air pump and air inlet pipe. This air is then injected into the wastewater in the aerobic tank through multiple aeration pipes with aeration holes, thus aerating the wastewater. A circulating pump draws cooling water from the cooling water tank and injects it into the spiral heat-conducting pipes. This cooling water flowing through the spiral heat-conducting pipes cools the wastewater in the equalization tank. The heated cooling water then enters a chiller for further cooling and finally flows back into the cooling water tank. A water temperature sensor monitors the water temperature in the cooling water tank. The monitoring and controller control the start and stop of the chiller based on the water temperature in the cooling water tank. The electric cylinder drives the density sensor and oil pump to move downwards. The density sensor can monitor the density of the wastewater, causing the inlet of the oil pump to move to the oil-water separation surface. The oil pump extracts the oil from the wastewater and discharges it through the oil guide pipe to prevent it from clogging and interfering with subsequent treatment equipment. Cooling water can be added to the cooling water tank through the water inlet, and the water inlet can be sealed by the sealing cap. The controller can operate and control the device.
