Description

Technical Field

[0001] This utility model relates to the technical field of wastewater treatment equipment for municipal engineering, and more particularly to a wastewater treatment equipment for municipal engineering. Background Technology

[0002] Municipal engineering refers to comprehensive urban infrastructure construction projects, encompassing seven core areas: transportation, water supply and drainage, public facilities, greening and landscaping, flood control and safety, underground pipelines, and urban renewal. Its aim is to enhance urban functions, ensure people's livelihood needs, and promote sustainable development. Wastewater treatment in municipal engineering includes removing insoluble pollutants and parasite eggs from sewage through physical methods. For example, using equipment such as screens and grates to remove large particles, or using sedimentation and filtration to remove suspended solids and sediments.

[0003] Chinese patent CN220334812U discloses a municipal wastewater treatment device, including a treatment tank. A base is located on the lower end of the treatment tank, and a filter plate is located inside the base. A limiting plate is located on the front side of the filter plate, and a threaded knob is located on the front side of the limiting plate, with a gear rod located behind the threaded knob. Two sets of rack rods are meshed on the upper and lower sides of the gear rod, and the two rack rods are slidably connected to the limiting plate. A plug-in plate is located on the front side of the filter plate, and a plug rod is located on the front side of the plug-in plate, with one end of the plug rod connected to the base. A chemical feeding mechanism is located on the outer wall of the treatment tank. The chemical feeding mechanism includes a hopper, a mixing box, and a first branch pipe. The first branch pipe is connected inside the hopper, and one end of the first branch pipe is connected to the inside of the mixing box. A liquid level gauge is located on the outer wall of the mixing box. This device allows for direct chemical addition without opening the tank lid and facilitates quick disassembly of the filter plate for maintenance, extending its service life. It is practical.

[0004] Existing wastewater treatment equipment for municipal engineering projects suffers from problems such as excessive accumulation of naturally settled impurities on the filter plates, resulting in a heavy filtration load and the need for frequent cleaning. To overcome these disadvantages, this invention provides a wastewater treatment device for municipal engineering projects. Utility Model Content

[0013] When in use, this wastewater treatment equipment for municipal engineering has the following advantages:

[0014] 1. In this solution, a base, U-shaped box, inlet pipe, outlet pipe, drain pipe, baffle, connecting frame, chute, screw, limit rod, receiving tank, sealing plate, and filter plate are installed. Wastewater is continuously discharged into the U-shaped box through the inlet pipe, with the water flowing from left to right. After being filtered by several filter plates, the water is discharged through the outlet pipe. As the wastewater flows from left to right, impurities and solids contained therein settle into the drain pipe due to gravity. The first motor drives the screw to rotate, thereby moving the connecting frame and baffle up and down along the chute, facilitating the opening and closing of the baffle. Closing the control valve of the inlet pipe moves the baffle downward, and the impurities and waste settled at the bottom of the U-shaped box are discharged through the drain pipe, making cleaning convenient and quick. Some impurities in the wastewater naturally settle to the bottom of the U-shaped box, reducing the filtration burden on the filter plates. The receiving tank is used to receive overflowing impurities and liquids. By unscrewing the fixing bolts, the sealing plate and filter plates can be removed for easy cleaning of the filter plates.

[0015] 2. In this scheme, a storage tank, pump body, delivery pipe, spray box, rotating shaft, stirring blade, fixed box, driven bevel gear, connecting shaft, and driving bevel gear are installed. The pump body operates to transport the agent in the storage tank to the spray box through the delivery pipe, and sprays it into the U-shaped box through several nozzles to mix with the incoming wastewater. The second motor operates to drive the connecting shaft and driving bevel gear to rotate, thereby driving the driven bevel gear meshing with it to rotate, and thus several rotating shafts rotate accordingly. The stirring blades are used to stir and mix the incoming wastewater and sprayed agent to improve the mixing uniformity. Attached Figure Description
