Purification system for disorderly discharged seepage water of iron-manganese mines

Abstract

The invention discloses a purification system for disorderly discharged seepage water of iron-manganese mines. The purification system comprises a storage tank, a lime tank, a natural ventilation device, a long fiber filter layer, an adjustable nickel-chromium alloy plate, a filter residue tank and a safety tank, wherein the storage tank, the lime tank and the safety tank are sequentially arranged; the storage tank comprises a water inlet end, and seepage water flows in from the water inlet end of the storage tank and flows out from the water outlet end of the safety tank; the long fiber filter layer is arranged between the lime tank and the safety tank; the filter residue tank is located below the lime tank; the lime tank and the filter residue tank are separated by the adjustable nickel-chromium alloy plate; the natural ventilation device comprises a plurality of ventilation pipes; and the ventilation pipes extend into the lime tank. The purification system can be used continuously and is convenient to clean, the suspended matter content of the filtered water body is remarkably reduced, recycling of residues is convenient and rapid through the design of the adjustable nickel-chromium alloy plate between the link tank and the filter residue tank, and reduction and recycling of pollution are effectively realized.

Description

technical field [0001] The invention relates to the treatment of polluted water, in particular to a system for purifying seepage water from ferromanganese ore mines with disorderly discharge. Background technique [0002] The seepage water of iron-manganese mines is characterized by large changes in water volume and quality, acidic wastewater, and contains a large amount of iron and manganese ions. Most of them are discharged directly without treatment, which will cause serious pollution. For iron and manganese wastewater, my country generally adopts the neutralization method to treat the discharge, and the commonly used neutralizers are limestone and lime. However, the lime neutralization treatment process requires treatment sites such as mixing reaction tanks and sedimentation tanks. Aeration or catalytic oxidation with nitric oxide requires a lot of energy and power, and the cost is high. [0003] There are some ferromanganese mine seepage water treatment systems in our ...
