Example 1:
the limited liability company of the Daniang mining industry of the Henan Steel group is an iron ore mining enterprise, and the production scale is 215 ten thousand tons per year. According to the requirement of the iron ore dressing process, the average industrial water consumption is 1250 tons/h, and the maximum daily water consumption is 2253.37 tons/h. The area of the iron mountain mining area is 4.32km2According to the construction requirements of green mines, running water landscapes such as ponds, fish ponds, fountains, water drops and the like are needed.
Based on the technical scheme, the utility model is utilized to reasonably divide and classify the mineral processing industrial drainage; the treatment process of the mineral processing tail water is integrated into a landscape water system, and the treatment approach is beautified by adopting an environmental concept. Because the pollution components of the mineral processing tail water are solid particles and impurities such as mineral powder and the like, the effect of purification treatment can be achieved by a physical treatment process and a slight biological treatment process; the method comprises three processing modes: clear water which meets the use requirement of industrial water and has good water quality directly enters a recycling circulating system; tail water containing more micro particles and poor water quality enters a landscape water circulating system of a mining area; pumping and draining the precipitated slag and slime to recharge the underground goaf; meanwhile, the physical treatment process (including plant interception, filtration and the like) and the biological treatment process of tail water treatment are used as landscape water circulation systems, so that the mobility of landscape water can be increased, and the effect of beautifying the environment is improved. The specific embodiment is as follows:
firstly, a water collecting and distributing tank (see fig. 1 to 4) with an oval horizontal cross section (which can save floor space, increase precipitation distance in limited space and improve precipitation effect) is arranged at a mineral separation water outlet of a mine enterprise, and mineral separation drainage is distributed and classified. The major axis of the elliptic water collecting and distributing pool is 20.0m long, the minor axis is 15.0m, the depth is 6.0m, reinforced concrete structures on half ground and half underground are adopted, and the lower part is subjected to rigid seepage-proofing and flexible seepage-proofing treatment;
the drainage end of the water collecting and distributing tank is provided with a clear water overflow outlet 2, a sewage discharge port 9 and sludge discharge ports 6 and 8 with different functions according to different heights. 5 clear water overflow outlets (with the height of 0.3m and the width of 1.0m, stainless steel grids are arranged on the overflow ports, 80-100 meshes of nylon water filter nets are arranged on the grids) 2 are radially arranged at the edge of the tank wall of the water outlet of the upper layer (at the position 2m away from the normal water level) along the water discharging direction, the discharged water directly enters an industrial water circulating system, and the water is reused; a sewage outlet (with the width of 0.5m and the height of 0.3m, and a gate and a stainless steel grating are arranged on the outlet) 9 is arranged at the position of the middle and lower layers, which is 1.5m away from the bottom of the pool, and is used for discharging water with poor water quality, the water discharged from the part enters a landscape water circulation system of a mining area, and the physical purification and biological evolution processes of sewage are completed through the landscape water circulation process;
for the convenience of slime deposition and discharge, the catchment reposition of redundant personnel bottom of the pool is ridge-shaped bottom of the pool (namely use oval major axis to set up into ridge-shaped symmetrical slope as the center) 7, set up two mud discharging openings 6, 8 at bottom of the pool drainage end bilateral symmetry, width 0.3m, height 0.3m, set up the valve on the mud discharging opening 6, 8, and use the mud discharging opening to set up U type drainage groove as the axis, the deposit slay in the pool, periodic use when the slime is thicker, slay, the slime that discharges from the slag discharging opening, the underground space in the mud can be via the pipe-line system who corresponds the design flows back to the collecting space in the dead zone.
The lower parts of the middle and lower drainage ports are provided with corresponding landscapes such as a lotus pond, a fish pond and the like, so that industrial drainage passes through the processes of physical treatment, biological treatment and the like in the landscape flowing water, a circulation path is lengthened, and the water quality can be fully treated and purified.
