 Zhucheng Bo Environmental Protection Technology Co., Ltd. specializes in producing sewage treatment equipment, sludge treatment equipment at an affordable price, improve the quality of service and dedication for you to solve all kinds of sewage sludge disposal problem of national unity Toll Free: 400- 086-4002 Sales Hotline: 0536-6376787 15006466999 I. Overview BSRF series of flotation equipment, using advection cell body, chosen partially dissolved air technology, it works with other flotation device is basically the same principle, but the structure has been a major changes. The equipment and dissolved air system package is installed on a chassis, compact, high efficiency dissolved air, beautiful appearance, small footprint, easy installation and light transport, power consumption province, easy to operate, easy to manage, good effect and so on. Second, the application as a flotation process water is widely used in sewage treatment and water supply projects, the equipment is suitable for: 1, paper pulp white water recycling and water reuse. 2, the removal of heavy metal ions; 3, refinery wastewater, oil separation; 4, coking wastewater removal of impurities; 5, dyeing Wastewater and impurities removal; 6, sludge, membrane biological treatment of various types of solid-liquid separation after; Third, the application object 1, sewage solid particle size is very small, 2, and the formation of floc particles themselves near or below the density of water, 3, it is difficult to achieve solid-liquid separation by precipitation of various sewage. 4, in the water: the algae can be used in high water, low temperature and turbidity water by purifying contaminated water and brine and other industrial raw materials. 5, liquid-liquid separation: separating and recovering the oil, the fine droplets of the organic solvent, a surfactant and a variety of metal ions from wastewater. 6, asking for a higher place than gravity sedimentation hydraulic load and solids load or restricted land. Four, the device features an equipment box with steel welded reinforcement through channels and angles for the whole reaction tank configuration reaction mixer, water and medicine to ensure adequate response. Catchment system consists of perforated pipes catchment cloth. 2, the release of the first working pressure: at 2.5Kg / cm3 or more, that is able to work effectively. Its release bubbles flat diameter is only about 30 microns in diameter. Surface load up flotation tank 12m3 / m2.h, the residence time of water in the pool just 10-20 minutes, deep pool only about 2m. 3, dissolved gas cylinders: The dissolved air jet device, water intake is automatically adjusted according to the solvent tank pressure, no special operation. Dissolved gas cylinders diameter 400mm (based on the amount of water to play a small adjustment). 4, dissolved gas water: You can adjust the amount of water dissolved gas concentration or suspended, depending on the nature of the water body, generally the reflux ratio (20 to 40%). 5, anti-corrosion materials and equipment: equipment internal corrosion using FRP corrosion. External using iron red rust after two spray-drying hammer paint two six, works a role: mainly played solid-liquid or liquid-liquid separation (while reducing COD, BOD, color, etc.). 2, the flotation process: after sewage into the contact zone flotation tank dosing reactions, full contact with the dissolved gas and water after release, so that the water and microbubbles mutual floc adsorption, and then into the separation zone. Floc microbubbles buoyancy effect in fall to the surface to form a scum layer. Lower water flows through the catchment basin to clean and emissions. After gathering scum on the water to a certain thickness, foam blowing machine by scraping into scum trough discharge. The precipitated sludge sludge discharge port. 3, dissolved gas and water production and release: water or water by dissolved air flotation pump pressure, the control valve into the dissolved gas cylinders, air under pressure conditions to dissolve in water, when after release unit, into the gas were sharply reduced, releasing large amounts of fine size, uniform size, dense and stable microbubbles. Seven, commissioning and commissioning of equipment: a debugging device (1), for all pipe flotation tank and cleaning the pool in order to avoid congestion. (2), the water pump, air compressor and various transmission parts inspection, manual transmission plate moving parts should be flexible, in accordance with regulations plus a good oil. (3) the power to start the pump, check its operation is normal, if an exception should be immediately removed. (4) to manually start the air compressor, check the operation of the gas production and pressure to meet the design requirements. (5) button to start shaving foam machine, check the direction of rotation, to ensure that the scum scum scraping direction, no-load operation 3-4 cycles should be no exception. 2, the test run
