Problems solved by technology
[0008] In order to solve the problems of the above-mentioned magnetic separation technology in the treatment of high-concentration wastewater in engineering practice, that is, the problem of insufficient purification capacity of the disk drive and poor water discharge effect when the concentration of suspended solids increases instantaneously or the concentration of suspended solids itself is relatively high, the magnetic separation technology is used. Separation technology has the advantages of small footprint and controls the investment cost of magnetic separation process. The present invention provides an integrated two-stage magnetic purification high-concentration wastewater equipment, which has no obvious increase in floor space and investment cost compared with existing disk drives. Under normal circumstances, the magnetic separation and purification process is set to two stages, i.e. primary magnetic separation and deep magnetic separation; further, the primary magnetic separation proposed by the present invention follows the principle of low cost and less land occupation; further, the present invention The proposed primary magnetic separation and deep magnetic separation constitute an integrated device, and the two-stage separation shares a screw slag conveying mechanism (including a spiral slag conveying tank and a slag conveying screw), which is conducive to the subsequent unified recovery and treatment of slag, and occupies less land. Compact, low energy consumption, low cost, strong ability to treat high-concentration wastewater, and good water discharge effect

The invention discloses integrated high-concentration wastewater two-stage magnetic purification equipment with the capability of realizing primary magnetic separation and deep magnetic separation of magnetic suspended matters or magnetic floc. The integrated high-concentration wastewater two-stage magnetic purification equipment comprises a machine cover, a rack, a water tank and a transmission system and is characterized in that the water tank is internally provided with a water inlet, a magnetic drum, a magnetic-disk pack, a spiral slag transportation mechanism and a water outlet sequentially, one end of a slag scraper of the magnetic drum is tangentially connected with the upper part of the magnetic drum, the other end of the slag scraper is close to the outer edge of the magnetic-disk pack, and the magnetic drum and the magnetic-disk pack share one spiral slag transportation mechanism. With the adoption of the integrated high-concentration wastewater two-stage magnetic purification equipment, wastewater enters the magnetic-disk pack with lower suspended matter concentration after crude separation purification and is then subjected to high-accuracy separation, the effluent quality is good, the equipment is compact, the investment is saved, and the integrated high-concentration wastewater two-stage magnetic purification equipment is more ideal technological equipment used for high-concentration wastewater magnetic separation purification.
Description
technical field [0001] The invention provides an integrated two-stage magnetic purification equipment for high-concentration wastewater, which belongs to the technical field of magnetic separation and purification of wastewater. Background technique [0002] Since the development of disk-type magnetic separation water purification technology abroad in the 1970s, magnetic separation and purification wastewater technology equipment represented by disk drives has been widely used in the water treatment industry, especially in the treatment of metallurgical wastewater. In recent years, disk magnetic separation technology has also been gradually applied to the purification of non-steel wastewater whose main goal is to remove suspended pollutants, such as mine water and landscape water. By adding magnetic powder and water treatment chemicals to the non-magnetic sewage, the non-magnetic suspended pollutants in the wastewater are mixed with the magnetic powder, flocculated into magn...
