Iron Chengchao transformation of industrial water systems Analysis

DN250 pipeline to the East mining, underground water will be transported to the selected plant water 1000m. Pool, as the iron ore industry Chengchao water. Decline of the total displacement of 2-430m level of the design and construction of metallurgical and mining 8 31 No. 5 Wastewater Pumping Station 2.2 concentrator processing plant regularly open parking, causing some production together in a short time to the turbid water ring pool, although clarify the normal operation of the water supply system, but the fixed transmission capacity is limited, with the pool water volume of 1000m processing plant is not enough, resulting in a large number of mineral production and efflux of water, this part of the external drainage and waste water plant and the nearby farmers choose to wash the mud water, waste rock are aggregated to the selection pool of Wastewater Pumping Station accident, because this part of the water with sediment, debris more, resulting in waste water pumping station into the slurry pipe-recurrent congestion, waste water pumping station can not normally drive, making the process a large number of industrial water tidal loss of iron. To this end Chengchao iron ore and metallurgical design of Changsha Research Institute of the joint, the technological transformation of the wastewater pumping station, installed in the center of the accident a large pool of mixing device, namely, round 700mm, speed: 136r/min, the motor is Ⅳ = I5kw, normal operation , the mixer working, so the middle of the accident bubble (water pipe near) the mud in suspension, so that the sand pump suction pipe is not blocked, no manual dredging and pumping stations at any time to resume normal operation. Pool into the sink in the accident to install a grille, grille 『can do welding steel erection, grill clearance spacing 20mm, to ensure that students can not get into an accident pool cleaning waste, waste water pumping station to resume normal operation. This part of the wastewater through sand pump transported to the 45mm pool enrichment processing, which flows into the solids with the bottom to the reservoir, to clarify the water into the pool for the election of Circulating recycling plant. 2.3 tailings return water pump station pontoon shift Yangjiawan tailings in l991 was officially put into production, along with the concentrator tailings discharged to the bank to increase the amount of underwater sand acute Wei to the tail Floating backwater pumping station to promote the end of 1997 draft of pontoon pump station for the return 1.9m, the end of suction pipe from the sand underwater 1.2m, resulting in tailings return water pump station pontoon pumping muddy water pipe phenomenon occurred, can not meet the industry water needs, in order to improve the tailings return water quality to improve the tailings back to the water, through on-site location, ship floating on the tailings return water pump station shift, a new water pumping station floating boat site can meet the needs of industrial water + back water from 184.54m / h, increased to 287m. / H. Backwater Pumping Station Shift pontoon plane shown in Figure 1. Regardless of location Driving Kids in a pontoon plane location Backwater Pumping Station Shift 3 Kids in social and economic benefits of industrial water Chengchao Iron has been relying on an external supply, the mine production has been restricted, water rising year by year, an increase of production cost, therefore, of industrial water mooring to transform, both the lower production costs, or the hollow of a tree management of water pollution and mining water reuse have become very urgent, significant. Renovation project took six months, invested a total of TUFS ¨ O million, l998 be completed in the end of April. The project by the city of Wuhan Iron and Steel Mining Company, and attached great importance to fully Ezhou sure this is a way to solve water pollution and water influx of iron ore mining is an effective way issues, the social effects of a huge benefit. Water per year by 1998, 1.35 million, the efflux of mine wastewater pollution compensation costs farmers 35 million per year, Taiwan's total 1.7 million yuan in 1998, invested Chengchao Iron ¨ 0 million, through the transformation of the original water system , built a completely self-enclosed industrial water recycling system, the new transformation of part of the annual running cost not more than 24 million in annual savings of water l11 million, a year later recovered the full investment. 4 Conclusion (1) Chengchao Iron industrial water system renovation project, after two months of trial operation showed that after the transformation of industrial water systems completed in September 1999 Liu Shu and other Chengchao Iron industrial water system renovation Comment Almighty meet Chengchao Iron industrial water needs . (2) The closed loop process water for industrial use, an annual saving of more than 600 million m, industrial water recycling water utilization rate also increased from 73. O5 increased to 9O. (3) Iron Chengchao reconstruction of industrial water systems, proved by the production, transformation of the industrial water system after the water supply network is simple, reliable production, scientific, rational, practical features, which not only increase the economic efficiency of enterprises, but also reduce the waste of water resources in mining, water use and mine is mine opened up a new way to waste water treatment.
