Abstract

The invention discloses foam scrapping type sewage treating equipment, and belongs to the field of water treatment. The foam scrapping type sewage treating equipment comprises an air floating tank, a foam scraping machine, a storage pool and a sludge tank, wherein the foam scraping machine is positioned at the upper part of the air floating tank; the storage pool and the sludge tank are positioned at one side of the air floating tank; the air floating tank is positioned above the storage pool; a pressure reducing device for suddenly decompressing a sewage medium is arranged inside the air floating tank; the sewage medium passes through the pressure reducing device, and then first flows into the air floating tank for solid-liquid separation, thus forming a flocculent mixture and a treated medium; the flocculent mixture enters the sludge tank under the action of the foam scraping machine; the treated medium flows into the storage pool. According to the foam scraping type sewage treating equipment disclosed by the invention, the sewage medium is suddenly decompressed and the pressure of the sewage medium is quickly released, thereby generating a large amount of micro air bubbles; the flocculent mixture in the sewage medium is enabled to float up and then is collected, thereby enhancing the high-efficiency water purifying capability of the foam scraping type sewage treating equipment; the decontamination ability is remarkable.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to a scraping type sewage treatment equipment. Background technique [0002] Sewage treatment equipment is mainly aimed at the evolutionary treatment of domestic wastewater or industrial wastewater. Scraping sewage treatment equipment is a common industrial sewage treatment equipment, which is widely used in papermaking, printing and dyeing, electroplating, leather, textile and petrochemical industries. [0003] In order to realize the purification treatment of industrial sewage, the foam scraping sewage treatment equipment is usually equipped with an air flotation tank and a foam scraper, through which the wastewater is separated from solid to liquid, and then the impurities in the wastewater are removed by the foam scraper. Chinese Patent Literature Publication No. CN201648035U discloses a fully enclosed sewage treatment air flotation tank, including a treatment tank, the two ends o...
