Problems solved by technology

[0003] However, the existing radial-flow secondary sedimentation tanks suitable for glass processing wastewater treatment still have the following disadvantages in the actual use process: First, the effect of relying on scrapers to scrape and collect sludge in use is not good. The sludge settled at the bottom of the pool is scraped into the sludge hopper, but after a long period of use, the bottom of the scraper is severely worn, resulting in a gap between the bottom rubber and the bottom of the pool, resulting in the problem of unclean scraping of the sludge , and because the particles with large mass are deposited at the bottom, the scraper not only cannot scrape off the sludge at the bottom, but also has secondary friction with the precipitated particles, which intensifies the wear; secondly, due to the unstable flow rate of the pool water, mud, water If the contact time is long, the sludge is prone to anaerobic gas generation inside the sludge, which will cause the sludge to float up and affect the water quality of the effluent. Moreover, the scraper at the bottom of the pool will agitate the sludge layer when scraping the sludge, which will not only aggravate the anaerobic gas generation pollution. If the mud floats up, the plants growing in the pool (such as moss, aquatic plants, etc.) will lose their adhesion and float up, affecting the quality of the effluent water

Abstract

The invention relates to the technical field of sewage treatment equipment, and discloses a secondary sedimentation tank suitable for glass processing wastewater treatment, including a tank body, a sludge bucket is provided at the bottom of the tank body, and one side of the sludge bucket is fixed A mud outlet pipe is installed, a central cylinder is fixedly connected to the middle of the sludge hopper, a water inlet pipe is fixedly connected to one side of the bottom of the central cylinder, and a water outlet pipe is fixedly connected to the upper end of the central cylinder. Through the setting of the mud scraping device, when the mud scraping device is installed, the mud scraper will stick to the bottom of the pool under the action of the air bag to prevent the gap between the mud scraper and the bottom of the pool, resulting in incomplete scraping and affecting the separation efficiency. When the mud scraper scrapes the sludge, the air bag has a tendency to compress downward under the static pressure of the water in the pool. When the mud scraper is worn out, the air bag will squeeze the mud scraper so that the mud scraper is always close to the pool To ensure that there will be no gap between the mud scraper and the bottom of the pool, and avoid the problems of incomplete scraping and poor mud scraping effect.

Description

technical field [0001] The invention relates to the technical field of sewage treatment equipment, in particular to a secondary sedimentation tank suitable for glass processing wastewater treatment. Background technique [0002] With the process of national industrialization and urbanization, the discharge of industrial and domestic sewage has increased significantly, and the treatment of sewage has become an urgent problem to be solved for sustainable development. Among them, a secondary sedimentation tank suitable for glass processing wastewater treatment is a utilization The sedimentation method is used to realize the solid-liquid separation of sewage. The sedimentation tank uses gravity to separate and remove solid pollutants from the water. The working principle is as follows: the sewage in the radial flow secondary sedimentation tank enters the central cylinder through the inlet pipe at a certain flow rate, And through the guide tube, it diffuses outward in the form of...
