First, an overview
With China's rapid economic development, people's living standards continued to improve, people have become increasingly demanding of the quality of life and living environment; rapid development consumes a lot of resources, resulting in a large number of waste, the threat to people quality of life of life, the development of economic pollution control, has become the consensus of modern society, the CPC Central Committee and State Council made a timely manner to the path of sustainable development, national development strategies to create a harmonious society, more pointed in the direction of the work for us. As the paper industry, cleaner production, waste water treatment has become a trend in the international arena, will also become a trend in the country, is the paper industry the bounden duty of.
Paper wastewater treatment technology and processing cost reasons, has been plagued by pulp and paper, making it a paper mill to have a heavy burden to design an efficient sewage treatment facilities has become a common paper industry and mechanical industry desire, my company in a timely manner with the international advanced sewage treatment technology, combined with the experience of many years wastewater treatment, design and development ZSF series of super-dissolved air flotation wastewater treatment equipment and technology, completely solve the problem of the paper mill wastewater treatment many paper mills use to prove the technical operations reliable, good water quality, processing cost, easy to operate, easy to master, by the use of home recognition and widespread praise.
CXX series of super-dissolved air flotation wastewater treatment equipment, application of new dissolved air mechanism, design new and unique system of dissolved gas, its excellent operating performance excellence in the treatment effect has been fully reflected in the industrial wastewater treatment.
Second, the structure and principles
Sewage processor CXX series of super-dissolved air flotation for the steel structure and its working principle is: the air pressure through the pump into the melting tank, under 0.5Mpa pressure is forced to dissolve in water, in the case of a sudden release, dissolved in The air in the water precipitates to form a float to close micro-bubbles rise slowly adsorbed on suspended solids density decreased to achieve the purpose of removal of SS and CODcr.
CXX series of super-dissolved air flotation wastewater processor structure from top to bottom consists of the following components:
A flotation machine:
Circular steel structure, is the main core of the water treatment machines. Internal release, uniform, sludge pipe, outlet pipe, sludge tanks, scraper and drive system. Release placed in the central location of the flotation machines, the key components to produce micro-bubbles and dissolved gas cylinders to the dissolved gas and water well mixed with the waste water in here, suddenly released, resulting in severe agitation and vortex to form a diameter of about 20-80um micro-bubbles, which is attached to the floc in the wastewater, thereby reducing the proportion of the rise of the floc, water thoroughly separated, both cloth the Cheng cone of structure, connected to the release on the main role is to separate the clean water evenly spread and the sludge in the tank, the outlet pipe are distributed in the tank the lower part, and through a vertical pipe connected to the tank the upper overflow, overflow export level adjustable handle, easy to adjust the tank water level, sludge pipe installed in the tank the bottom for the discharge of sediment, tank upper part of the sludge tank scraper slot scraper kept turning constantly floating sludge scrape the sludge tank and gravity to the sludge tanks.
2, dissolved air system
Dissolved air system is mainly composed of dissolved gas cylinders, gas tank, air compressor, high pressure pump, dissolved gas cylinders is the most crucial part of the system, its role is to achieve full contact of the water and air to accelerate the air dissolved. It is an airtight pressure steel tanks, the internal design of the baffle sleeve, can accelerate the dispersion of the gas and water, mass transfer process, to improve the efficiency of dissolved air.

Add coagulation drugs the PAC in the quenched and tempered pool wastewater to be preliminary separation, flocculation, sedimentation, and then by the sewage pumped to the flotation machine in the role of the flocculant PAM to form larger flocs. Since the capture of a large number of micro-bubbles and flocs greatly reduced the proportion of floating, water thoroughly to separate and flow away from the overflow into the aerobic rapid filter, where water further oxygen, and filtration and absorption through the filter to be get rid of the color and some sediment, and water into the sedimentation clarifiers, standing settlement to clarify that the final flow tanks reuse or discharge.
Float to the top of the sludge flotation machine, scrape the sludge tank and gravity to the sludge drying pool of sludge pumped into a sludge filter press, filter press, the formation of filter cake, outside Wan landfill, or mixed with coal burning. The filter press effluent back to the sedimentation tank. If you continue to invest in a cardboard machine, the sludge can also be directly used to produce high-grade cardboard, not only to eliminate the secondary pollution, you can also create great value for money.
