Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture wastewater treatment, in particular to an aquaculture wastewater treatment device. Background Art

[0002] Aquaculture wastewater refers to wastewater generated during the aquaculture process, mainly from animal excrement and cleaning and disinfection of farms. These wastewaters usually contain high levels of organic matter, nutrients such as nitrogen and phosphorus, as well as microorganisms such as bacteria and viruses. If they are discharged directly without treatment, they will cause serious pollution to the environment. Therefore, aquaculture wastewater needs to be treated before it is discharged. The application number is:

[0003] The "aquaculture wastewater treatment device" disclosed in "CN214319228U" has solved the technical drawbacks of the inconvenience in discharging the precipitated sludge, but in actual use, devices with similar structures still have many defects. For example, the movement when discharging the precipitated sludge is large, which will cause the precipitated sludge to disperse, thereby affecting the overall quality of the device for aquaculture wastewater treatment, and it does not have the function of continuous sludge discharge, resulting in low efficiency of the device for aquaculture wastewater treatment; at the same time, most of them adopt an open structure, which is easy to produce hydrogen sulfide gas during the treatment of aquaculture wastewater. Hydrogen sulfide is a gas with a strong irritating odor, which can cause symptoms such as headache, dizziness, nausea, vomiting and difficulty breathing. Therefore, it will cause harm to the health of the staff when in use, so it is necessary to design an aquaculture wastewater treatment device. Utility Model Content

[0006] A farm wastewater treatment device using the technical solution has two groups of mixing chambers for storing wastewater. PAC and PAM can be added to the wastewater in the two groups of mixing chambers manually or with external equipment, so that PAC and PAM farm wastewater can be mixed for treatment. PAC and PAM can be mixed with farm wastewater for flocculation treatment.

[0007] After mixing, the aquaculture wastewater flows into the transition chamber, and the aquaculture wastewater in the transition chamber flows into the sedimentation chamber through the conduction pipe. The sedimentation chamber can temporarily store and flocculate the wastewater mixed with PAC and PAM agents. The flocculated sludge will settle at the bottom of the sedimentation chamber, and the separated clean water will be discharged through the drain port and the clean water cover, thereby realizing the function of treating the aquaculture wastewater.

At the same time, the exhaust pipe is connected to the recovery pipe, so that the hydrogen sulfide gas generated during the operation of the device can be guided and collected, avoiding the leakage of hydrogen sulfide gas to cause physical harm to the staff, and increasing the safety of the device during operation.

[0009] Preferably, a stirring motor is fixedly installed on one side of the bottom of the treatment box, and the output end of the stirring motor extends to the mixing chamber and a stirring paddle is fixedly installed. The stirring motor drives the stirring paddle to rotate to accelerate the speed and quality of mixing PAC and PAM with aquaculture wastewater.

[0010] Preferably, a clean water pipe is fixedly connected to the bottom of the clean water cover, and a mud discharge pipe is fixedly connected to the other side of the bottom of the mud pipe. The clean water pipe is connected to an external pipeline so that clean water after mud and water separation can be discharged, and the mud discharge pipe can be connected to an external sewage discharge, so that subsequent equipment can process the sludge.

[0011] Preferably, an observation window is fixedly installed inside the closing plate, and an operating rod is fixedly installed outside the observation window.

[0012] Preferably, an operating table is fixedly installed below the front and back of the processing box, and a support column is fixedly installed at the bottom of the operating table. The operating table is convenient for workers to stand when observing and maintaining the device, and the support column can install and support the operating table, increasing the stability of the operating table during operation.

[0013] Preferably, a support frame is fixedly installed at the bottom of the processing box, and a foot plate is fixedly installed at the bottom of the support frame. The support frame can support the bottom of the device during operation, and the foot plate increases the force-bearing area of ​​the bottom of the support frame, thereby improving the stability of the support frame when supporting the device.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. By setting the cooperation between the sedimentation chamber, the sludge pipe and the sludge discharge impeller, the sedimentation chamber can store the aquaculture wastewater mixed with flocculants, and the aquaculture water level can separate the mud and water in the sedimentation chamber, and the separated sludge will settle in the sludge pipe. The sludge discharge impeller rotates in the sludge pipe to drive the internal sludge to be discharged, so that the sludge after the mud and water separation can be discharged continuously, and the sludge discharge method of the impeller has less vibration during operation, which avoids the situation that the sludge in the sedimentation chamber is crushed when discharged and affects the quality of clean water, thereby increasing the stability of the device during operation and improving the quality of aquaculture wastewater treatment.

[0016] 2. By setting the coordination between the mounting plate and the closing plate, the exhaust hood and the fan, the mounting plate and the closing plate can close and seal the top of the device during operation, thereby avoiding the outflow of hydrogen sulfide gas generated when the device separates the cement water of aquaculture wastewater. The exhaust hood and the fan can extract and collect the hydrogen sulfide generated by the aquaculture wastewater treatment in the device, which is convenient for the staff to centrally treat the hydrogen sulfide gas and avoid the hydrogen sulfide gas flowing into the environment to cause harm to the health of the staff, thereby increasing the safety of the device during operation.
