[0003] Currently, wastewater treatment plants generate sludge from the treatment of industrial and domestic wastewater. Besides inorganic components existing in the form of minerals, this sludge also contains a large amount of organic pollutants. Because this type of sludge has a high water content, is abundant, and is enriched with high concentrations of pollutants, improper treatment can pose a threat of secondary pollution to the environment.

[0004] Commonly used traveling scraper-suction sludge machines are mainly installed at the top of horizontal flow sedimentation tanks. They consist of an above-water section and an underwater section. The scraper blades of the underwater section are usually the same width as the tank body, installed horizontally at a 180-degree angle, with a ground clearance of about 50mm. The bottom of the structure is flat, which facilitates the automatic back-and-forth movement of the scraper blades along the length of the tank. The bottom sludge pump sucks up sludge with a high water content and discharges it into a sludge storage tank. The disadvantages are that the sludge pumped by the sludge pump has a relatively high water content during operation, and the equipment's operating cycle is relatively short. Utility Model Content

[0036] The application changes the traditional horizontal flow sedimentation tank 1 with flat bottom into a sedimentation tank with rectangular sludge groove 101, which can accommodate sludge in layers, and adds X-shaped mud scraping plate 3, so that part of the sludge on the bottom plane of the horizontal flow sedimentation tank 1 above the sludge groove 101 is scraped into the sludge groove 101 and collected to the center of the X-shaped center, and then the sludge is sucked out of the sedimentation tank by the suction device 2.

[0037] The suction device 2 is specially matched with the sludge suction port of the sludge groove 101, the transverse pipe 6 connected with the mud pumping pipe 5 is arranged, and the sludge with low water content in the sludge groove 101 is sucked into the horizontal flow sedimentation tank 1 through the suction port 601 similar to the suction port of the dust collector, so as to increase the amount of sludge sucked out of the bottom of the sedimentation tank, greatly improve the concentration of the sludge sucked out, reduce the running frequency of the scraping and sucking machine, and save the operation cost of the enterprise.
