The cross-section of the right side inside the wastewater treatment tank is arc-shaped, and the end of the filter plate is in contact with the right side of the wastewater treatment tank. A water pumping component is provided at the right end of the upper surface of the wastewater treatment tank. This invention can improve the mixing efficiency of wastewater and activated sludge, ensure uniform oxygen supply, and improve the filtration effect.

The invention belongs to the technical field of automatic planting, and particularly relates to a sprouting vegetable high-quality and high-yield planting system which comprises a planting workshop and an automatic harvesting system connected with the planting workshop, the planting workshop is a closed area, and an annular suspension type assembly line is arranged in the planting workshop; the annular suspension type assembly line is used for suspending and transporting multi-layer plane planting plates for medium-free planting, and a novel mist spraying area and a light supplementing system are arranged on a conveying path of the annular suspension type assembly line. And a temperature / humidity control system and a water purification magnetization system which are communicated with the internal environment of the planting workshop based on a pipeline communication mode are arranged outside the planting workshop. By adopting a mode of combining medium-free cultivation and sports planting and controlling crop growth conditions in the whole process, any harmful residues are completely eradicated, unstable factors and large workload of artificial planting are greatly reduced, standardized production of crops is realized, and the market competitiveness of products is fully improved.

The utility model discloses a kind of air supply valves, including valve core and valve body, valve cavity is equipped in valve body, one end of valve core is rotationally arranged in valve cavity, and valve core is connected between sealing and valve body;The outer end surface of one end of valve core arranged in valve cavity is equipped with first gas outlet, second gas outlet, third gas outlet and fourth gas outlet, one end of valve core away from valve body is equipped with air inlet end pipe and knob, first gas outlet, second gas outlet, third gas outlet and fourth gas outlet are all communicated with air inlet end pipe.The technical effects reached are as follows: when using, the rotation angle of valve core is controlled by knob rotation, the simultaneous opening, simultaneous closing or one opening one closing of first air outlet end pipe and second air outlet end pipe can be controlled, the on-off air state of two pipelines can be flexibly controlled in whole valve, after being applied to the oxygen supply pillow of double pipelines side-by-side arrangement, the diversified functions such as regional oxygen supply, uniform oxygen supply of oxygen supply pillow can be realized.

This utility model discloses a catalytic oxidation reactor for wastewater treatment, relating to the field of wastewater treatment technology. The utility model includes a fixed chamber, an exhaust plate, a conveying frame, and a fixed frame. An exhaust plate is fixed to the bottom of the fixed chamber, and a support frame is fixed to the inner wall of the fixed chamber above the exhaust plate. A conveying frame is supported at the top of the support frame. A corrugated plate, made of titanium catalyst material, is fixed to the middle of the inner wall of the conveying frame. Gas delivery holes are evenly spaced through the folded lines at the top and bottom of the corrugated plate. Several light-emitting lamps are evenly spaced on the inner wall of the conveying frame below the corrugated plate. A limiting frame is abutted against the top of the conveying frame, and a fixed frame is fixed to the upper edge of the outer side of the limiting frame. This utility model, by setting up a fixed chamber, an exhaust plate, a conveying frame, and a fixed frame, solves the problems of uneven oxygen supply during catalytic oxidation, which affects catalytic stability, and insufficient catalyst activation in the catalytic structure.
