Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and more specifically to a wastewater purification device for aquaculture. Background Technology

[0002] Aquaculture wastewater is a high-concentration organic wastewater containing a large number of pathogens. After a large amount of organic matter enters the water body, the decomposition of the organic matter will consume a large amount of dissolved oxygen in the water, causing the water to smell bad and leading to the death of a large number of aquatic organisms. Nitrogen and phosphorus can cause eutrophication of the water body, which seriously affects the surrounding environment and the health of residents. Therefore, purification equipment is needed to purify aquaculture wastewater.

[0003] The treatment of livestock wastewater typically involves solid-liquid separation followed by anaerobic digestion and then aerobic treatment. However, such wastewater treatment facilities require significant investment and have high operating costs, making them unaffordable for rural areas with slower development and weaker economic foundations. While simple equipment with basic processes offers convenient purification, it often fails to meet discharge standards. Furthermore, livestock wastewater contains solid impurities such as feces, which are difficult to separate from the wastewater and can easily cause blockages.

[0004] Therefore, providing a wastewater purification device for aquaculture that is simple in structure, easy in process, has good purification effect, and is low in cost has become an urgent problem to be solved. Utility Model Content

[0041] Operating principle of this device:

[0042] Poultry farming wastewater enters the filtration zone 11 through the inlet pipe 111. The filter screen 1141 filters out the insoluble impurities in the poultry farming wastewater, and then the wastewater enters the adsorption zone 12. Oxygen is introduced into the adsorption zone 12 through the air inlet pipe 19 for aerobic treatment. At the same time, the motor 1121 is turned on, and the output shaft 1212 drives the stirring rod 1213 to start rotating. The blades 1214 start to stir the wastewater and adsorbent 123, improving the aerobic treatment efficiency and effect, as well as the adsorption efficiency and effect. After adsorption and fermentation are completed, the valve 161 is opened, and the purified water flows out of the box 1 through the channel 16 and the drain pipe 17. The filter plate 1221 prevents the adsorbent from flowing out with the purified water.

[0043] After processing, motor 211 is turned on. The meshing of gears 221 and 211 drives the transmission shaft 222 to rotate, simultaneously causing crankshaft 223 and crank 224 to rotate. Through the movable connection of connecting rod 225, connecting rod 226, and crank 224, connecting rod 226 and scraper 1152 reciprocate linearly. Scraper 1152 scrapes away insoluble impurities from filter screen 1141. During the reciprocating linear motion of scraper 1152, protrusion 1153 contacts plate 1311 and plate 2411, gradually pushing them apart, connecting filter zone 11 to discharge zone 13 and discharge zone 24. Simultaneously, scraper 1152 pushes impurities towards discharge zone 13 and discharge zone 24, and then discharges them from discharge port 132 and discharge port 242.

[0044] During the process of cleaning the filter screen 1141 with a scraper, clean water is introduced into the water inlet pipe 121, and the nozzle 122 will further clean the filter screen 1141. At this time, the valve 151 is opened, and the clean water passes through the filtration zone 11, the adsorption zone 12 and the channel 15 in sequence, enters the sewage discharge zone 14, and is discharged from the box 1 through the sewage discharge port 142.

[0045] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
