Description

Technical Field

[0001] The present invention relates to a sludge residue cleaning mechanism for a sludge collection area of a horizontal tube sedimentation tank and a method for use thereof, and relates to a mechanism and a method for use thereof, belonging to the technical field of sewage treatment, and particularly to a cleaning mechanism that can float up and down in a sludge collection area, diverting water flow together with sludge residue therein for cleaning, and preventing sludge residue from continuously floating in sewage, increasing sewage turbidity, and reducing effluent water quality. Background Art

[0002] Upgrading municipal sewage treatment plants can improve effluent quality, reduce pollutant loads, mitigate the risk of eutrophication, and increase water resource utilization in water-scarce areas. However, sewage plant upgrades present land challenges. How to address this challenge within existing land resources will be a major challenge for the domestic environmental protection industry. Sedimentation tanks, structures that remove suspended solids from water by sedimentation, are widely used in wastewater treatment. Traditional sedimentation tanks have slow flow rates, long settling times, and long sedimentation distances for suspended solids, making them prone to pipe blockage and alum leakage.

[0003] In order to solve the above problems, the applicant proposed a horizontal tube sedimentation tank in another case, including a sedimentation tank, a water inlet is provided on the left side of the sedimentation tank, the water inlet is connected to a pipeline mixer, a dosing port is provided on the pipeline mixer, and the dosing port is connected to the dosing equipment through a pipeline. The sedimentation tank is provided with a flocculation area, a water distribution area, a sedimentation area and a water collection area from left to right. The inner cavity of the flocculation area is provided with a flocculation reactor, and the flocculation reactor is located above the water inlet. A water distribution flower wall is provided on the right side of the top of the flocculation area to connect with the water distribution area. A water distribution flower wall is provided on the right side of the top of the water distribution area to connect with the horizontal tube sedimentator. The horizontal tube sedimentator is located above the inner cavity of the sedimentation area. A mud collection area is provided below the horizontal tube sedimentator, and a water distribution flower wall is provided on the right side of the top of the horizontal tube sedimentator to connect with the water collection area. The device applies Ha Zhen's "shallow sedimentation theory" to shorten the sedimentation distance of suspended matter, avoiding the occurrence of suspended matter clogging pipes and alum leakage; suspended matter settles to the sludge collection area to produce sludge, most of which will be discharged through the sludge discharge pipe, while the remaining sludge residue will be suspended in the water and is relatively dispersed and difficult to be discharged directly from the sludge discharge pipe. The sludge residue will continue to float in the sewage during subsequent sewage impact, increasing the sewage turbidity and thereby reducing the effluent water quality. Summary of the Invention
