A suspended floating tank tank foam collection and elimination device

Abstract

The invention relates to a suspension floating type box tank foam collecting and eliminating device. The device comprises a plurality of foam collecting tanks, wherein the foam collecting tanks are connected into a whole and floated on the liquid surface of a tank body, so that the foam which overflows the tank body of the collecting tank is collected; and a spraying device is arranged above the foam collecting tank so as to spray antifoaming agent liquid in the foam collecting tank, and antifoaming is carried out in the foam collecting tank to form liquid. A suspension floating type box tank foam guiding device is used, so that the problem that the foam produced too much by a water treatment aeration tank overflows outside the wall of tank can be solved, and an antifoaming system can not be polluted due to the addition of the antifoaming agent; and the antifoaming agent can be recycled after being collected, so that the dosing amount is reduced.

Description

technical field [0001] The invention relates to a foam collection and elimination device used in the fields of food fermentation, papermaking, mineral processing, landfill leachate and other water treatment foam collection, foam separation and defoaming. Specifically, the invention relates to a suspended floating tank foam Collect and eliminate devices. Background technique [0002] With the continuous development of the economy, the protection of the ecological environment and the rational and effective use of resources have become the focus of people's increasing attention. At present, the environmental pollution in our country is serious. The discharge of industrial wastewater and urban domestic wastewater has caused environmental pollution. At the same time, the excessive exploitation and use of water resources has made our country face a serious water crisis. [0003] At present, it is an indisputable fact that mankind is facing a water crisis. Although the country has...

Problems solved by technology

[0003] At present, it is an indisputable fact that mankind is facing a water crisis. Although the country has increased investment in urban infrastructure construction and environmental protection, strengthened comprehensive environmental management, and effectively controlled the total amount of pollutant discharge, the environmental quality of some areas and cities has improved. , but according to the statistical analysis of environmental monitoring results, my country's water pollution situation is still very severe, the total discharge of various pollutants is large, and the pollution degree is still at a fairly high level

[0004] At the same time, with the acceleration of urbanization, the increase in water consumption and the increase in drainage, the demand for sewage treatment has also increased. Regeneration of sewage treatment and the use of regenerated water have also become effective ways to alleviate the pressure on water resources. Currently, the methods for sewage treatment There are many kinds, but most of the sewage treatment methods require anaerobic and aerobic biological treatment processes. During the biochemical water treatment process, the biochemical aerobic aeration tank will be filled with a large amount of air. Due to the high content of organic matter in the water, The organic components are complex, the activated sludge of the aeration mixture is aging, the influent contains excessive detergent or surfactant, filamentous bacteria expand, and the factors such as unstable influent water quality, temperature changes, improper biochemical adjustment and other factors form a large number of foams , too much foam will bring many disadvantages. In severe cases, foam will overflow the pool wall, seriously affecting the normal operation of the sewage treatment process, and causing certain difficulties in the operation, operation and control of the sewage treatment plant. Serious affect effluent quality

[0005] At present, because mechanical defoaming is difficult to achieve, in order to eliminate a large number of bubbles generated in the water treatment process, the existing technology usually uses spraying water or defoaming agents to defoam, and simple spraying of water will still cause foam to overflow the pool wall phenomenon, and a large amount of defoaming agent will affect microorganisms and subsequent treatment processes and increase costs
