This invention discloses a sludge thickening tank for wastewater treatment plant construction, belonging to the field of sludge thickening technology. It includes a thickening tank with a conical sludge hopper at the bottom and a sludge discharge port at the bottom of the hopper. A sludge discharge pipe is located at the lower end of the discharge port. An overflow weir is slidably connected to the inner curved surface of the thickening tank, and a clear water tank is fixedly connected to the lower end of the outer curved surface. A fixed plate is radially fixedly connected to the upper end of the clear water tank, and a stirring assembly is fixedly connected to the middle of the fixed plate. A fixed chamber is fixedly connected to the upper end of the stirring assembly, and a second drive motor is fixedly connected to the upper end of the fixed chamber. An intermediate shaft and a retraction rod are slidably connected to the fixed chamber. This invention achieves advantages such as high-efficiency thickening, intelligent control, and wear resistance through an innovative structure of adjustable overflow weir + intelligent valve + dual-drive stirring, while also considering ease of operation and safe maintenance, making it suitable for modern wastewater treatment needs.

The utility model provides a kind of short flow prevention cyclone grit chamber with oil and slag removal function, including inlet channel, pool body, water collecting cylinder, outlet channel, sand discharge emptying pipe and slag discharge channel etc. Speed-regulating pusher consisting of frequency conversion motor, paddle and flow velocity meter is equipped in inlet channel, and inlet flow rate can be adjusted according to water volume. The bottom of pool body is conical cylinder, and water is discharged from the bottom of central water collecting cylinder, to avoid short flow. There is also slag remover, which removes oil and slag by driving motor driving scraper and stirring blade on rotating shaft. The grit chamber solves the problem of short flow, poor oil and slag removal of traditional equipment by speed-regulating pusher and flow guide water collecting cylinder, realizes "three-phase separation", improves sand removal efficiency, and does not increase land occupation, which can be used for existing grit chamber modification and is suitable for sewage treatment pretreatment.

This invention discloses a decentralized airlift reoxygenation circulating biological denitrification wastewater treatment device, employing an integrated inner and outer cylinder design, encompassing wastewater treatment, sludge-water separation, and discharge, with a complete process and reasonable structure. The area between the inner and outer cylinders forms a circular wastewater treatment zone with circulating flow, encompassing a two-stage AO biological denitrification process. It eliminates the need for nitrification liquor recirculation, exhibiting excellent denitrification effect, resistance to shock loads, and ease of management. The inner side of the inner cylinder serves as a sedimentation zone, with periodic manual or mobile sludge removal. An airlift device provides circulation power and pre-oxygenation; the circulating water volume is adjusted by regulating the air supply, thereby controlling the nitrification liquor recirculation ratio. The device consumes only one air pump, which supplies air to both the airlift device and the aeration device, resulting in low investment, low energy consumption, and easy management. Fixed supports and rope-type fiber packing are installed throughout the wastewater treatment zone, effectively preventing packing blockage and short-circuiting problems, and facilitating the timely discharge of detached biofilm.

This utility model discloses a light source module with uniform heat dissipation, relating to the field of heat dissipation devices. The light source module includes: a lamp body, a heat dissipation pipe, an air guide shell, and a first heat sink. A first heat source and a second heat source are located on the left and right sides of the lamp body. The heat dissipation pipe includes a first section and a second section. The air guide shell includes an air duct, an air inlet, a first air outlet, and a second air outlet. The air duct has a recessed internal structure. The first air outlet is located on the left side of the air duct, the second air outlet is located on the right side of the air duct, and the air inlet is located in the middle of the air duct. The first section of the heat dissipation pipe is attached to the first heat source, and the first heat sink is attached to the second heat source. The air guide shell is attached to the lamp body. By utilizing the heat dissipation pipe and heat sink to absorb and dissipate heat from the heat sources, and in conjunction with the air guide shell, uniform heat dissipation is achieved for heat sources with varying heat levels. Even using a single fan can achieve efficient heat dissipation, reducing operating costs.
