Description

Technical Field

[0001] This utility model relates to the technical field of wastewater treatment, and in particular to a device for treating toilet wastewater by breaking point chlorination. Background Technology

[0002] Breakpoint chlorination is a method of removing nitrogen from wastewater by adding a sufficient amount of chlorine to convert ammonia nitrogen into nitrogen gas. It has wide applications in wastewater treatment. In the prior art, a utility model patent with patent application number 202222622916.3 discloses an environmentally friendly toilet wastewater treatment device, which mainly includes a filter cylinder, a sedimentation tank, and an aeration device. When treating wastewater, the wastewater is first passed through the filter cylinder to filter out solid impurities, and then the filtered wastewater enters the aeration device for further treatment. However, the inventors believe that this method has the following problems: due to the high viscosity and poor fluidity of the wastewater, after it enters the filter cylinder, it relies solely on its own gravity for filtration, resulting in low filtration efficiency, slow wastewater treatment speed, and inconvenience. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a toilet wastewater breakpoint chlorination treatment device that promotes the filtration speed of sewage on the filter cartridge, improves the sewage treatment efficiency, is easy to use, and has high practicality.

[0004] This utility model discloses a toilet wastewater breakpoint chlorination treatment device, comprising a base plate, a support frame, and a wastewater treatment tank. The wastewater treatment tank is fixedly installed on the upper part of the base plate via the support frame, and has an internal chamber. It also includes a filter cylinder, a feeding pipe, a conveying mechanism, a pressing mechanism, and a stirring mechanism. The filter cylinder is fixedly installed on the upper part of the wastewater treatment tank chamber, and has a cavity inside. The filter cylinder has multiple sets of filter holes communicating with the cavity. The pressing mechanism is installed on the filter cylinder and the wastewater treatment tank, and has a pressing function. The feeding pipe is installed on the right side of the wastewater treatment tank and communicates with the tank. A valve is installed on the feeding pipe. A drain pipe communicating with the chamber is located at the lower part of the wastewater treatment tank, and a valve is installed on the drain pipe. The stirring mechanism is installed on the wastewater treatment tank and has a stirring function. The conveying mechanism is used to feed water into the cavity of the filter cylinder. This system internally transports wastewater. When treating toilet wastewater, the wastewater is first conveyed into the cavity of the filter cartridge via a conveying mechanism. Simultaneously, a squeezing mechanism compresses the wastewater within the filter cartridge cavity, causing it to be discharged through filter holes into the wastewater treatment tank chamber. This leaves solid impurities in the wastewater within the filter cartridge cavity. Then, sufficient hypochlorite is added to the wastewater treatment tank chamber through a feeding pipe to chlorinate the wastewater. This causes the ammonia nitrogen in the wastewater to react with the hypochlorite, converting it into nitrogen gas which is then discharged from the wastewater, thus denitrifying it. The denitrified and chlorinated wastewater is then discharged through a discharge pipe for further treatment. During filtration, the wastewater is compressed within the filter cartridge, accelerating the filtration speed and improving treatment efficiency. It is convenient to use and highly practical.

[0005] Preferably, the conveying mechanism includes a conveying pump, an infusion pipe, a delivery pipe, a drain pipe A, a drain pipe B, and two sets of one-way valves. The conveying pump is fixedly mounted on the base plate, and its output end is connected to the delivery pipe via the infusion pipe. The input ends of drain pipe A and drain pipe B are both connected to the delivery pipe, and their output ends are respectively connected to the left and right sides of the filter cartridge cavity. The two sets of one-way valves are respectively fixedly mounted on drain pipe A and drain pipe B. When conveying sewage into the filter cartridge cavity, the conveying pump is connected to the external toilet sewage, and then the conveying pump is turned on, allowing the toilet sewage to enter drain pipe A and drain pipe B sequentially via the infusion pipe and delivery pipe. Afterward, the toilet sewage enters the filter cartridge cavity via drain pipe A and drain pipe B, thus facilitating the conveying of toilet sewage.

[0006] Preferably, the extrusion mechanism includes a hydraulic cylinder, a push rod, and a push plate. The hydraulic cylinder is fixedly installed at the left end of the sewage treatment tank. The push rod is slidably installed on the filter cylinder and the sewage treatment tank, with the left end of the push rod connected to the output end of the hydraulic cylinder. The push plate is fixedly installed at the right end of the push rod and slidably installed in the cavity of the filter cylinder. The push plate and the cavity of the filter cylinder are connected in a sealed sliding manner. When toilet sewage enters the cavity of the filter cylinder, the hydraulic cylinder is opened, and the hydraulic cylinder causes the push plate to move left and right through the push rod. During the movement of the push plate to the right, it extrudes the sewage in the right part of the filter cylinder cavity through the filter holes on the filter cylinder. When the push plate moves to the left, it extrudes the sewage in the left part of the filter cylinder cavity through the filter holes on the filter cylinder, thereby increasing the filtration speed of the sewage on the filter cylinder.

[0007] Preferably, the stirring mechanism includes a motor, a rotating shaft, and multiple sets of stirring blades. The motor is fixedly installed on the left side of the sewage treatment tank, and the rotating shaft is rotatably installed on the sewage treatment tank. The left end of the rotating shaft is connected to the output end of the motor. The multiple sets of stirring blades are all fixedly installed on the rotating shaft and are located in the lower part of the sewage treatment tank chamber. When hypochlorite is added to the lower part of the sewage treatment tank chamber, the motor is turned on. The motor rotates the multiple sets of stirring blades through the rotating shaft, promoting the movement of toilet sewage and hypochlorite in the lower part of the sewage treatment tank chamber, so that hypochlorite can be evenly distributed in the toilet sewage, which facilitates the chlorination treatment of toilet sewage.

[0008] Preferably, the filter cylinder is provided with sealing cover A and sealing cover B on its left and right sides respectively. The push rod is slidably connected to sealing cover A on the left and right sides. Sealing cover A and sealing cover B are respectively installed on the left and right sides of the filter cylinder by bolts. The sewage treatment tank is provided with an opening communicating with the chamber, and a sealing door is provided outside the opening. When it is necessary to clean the solid impurities in the cavity of the filter cylinder, the sealing cover A and sealing cover B can be opened to clean the solid impurities in the cavity of the filter cylinder, which improves convenience.

[0009] Preferably, the wastewater treatment tank is equipped with a chloride ion concentration detector; this facilitates the monitoring of chloride ion concentration in the wastewater at the bottom of the wastewater treatment tank chamber.

[0010] Preferably, the upper part of the sewage treatment tank is provided with an exhaust pipe; this arrangement facilitates the discharge of gas from the sewage treatment tank chamber.

During toilet wastewater treatment, the wastewater is first conveyed into the cavity of filter cartridge 4 via a conveying mechanism. Simultaneously, a squeezing mechanism compresses the wastewater within the cavity of filter cartridge 4, causing it to be discharged through filter holes into the chamber of wastewater treatment tank 3. This leaves solid impurities in the wastewater within the cavity of filter cartridge 4. Then, sufficient hypochlorite is added to the chamber of wastewater treatment tank 3 via a feeding pipe 5 to chlorinate the wastewater. This causes the ammonia nitrogen in the wastewater to react with the hypochlorite, converting it into nitrogen gas which is then discharged from the wastewater, thus denitrifying it. The denitrified and chlorinated wastewater is then discharged through a discharge pipe for further treatment. During filtration, the wastewater is compressed within filter cartridge 4, increasing the filtration speed and improving wastewater treatment efficiency. It is convenient to use and highly practical.
