Mine wastewater circulating treatment system

Abstract

The invention relates to the technical field of wastewater circulation treatment, in particular to a mine wastewater circulation treatment system which comprises a settling tank, an acid-base neutralization tank and a filter pressing tank. A first water inlet pipe is arranged on the top surface of the settling tank, and a rough filtration grating plate is arranged on the top surface of the settling tank; the side wall of the settling tank is connected with a water inlet pipe II and a flocculating agent pipe; a drawing groove is formed in the side wall of the settling tank, and a filtering drawer is inserted into the drawing groove; an activated sludge treatment mechanism is arranged in the settling tank, the settling tank is connected with a water outlet pipe I, and the water outlet pipe Iis connected with a lifting water pump communicated with the acid-base neutralization tank; the acid-base neutralization tank is connected with a second water outlet pipe, the second water outlet pipe is communicated with the filter pressing tank through a suction pump, a filter pressing plate is arranged in the filter pressing tank, and a water suction pump is fixed to the top surface of the filter pressing tank. The system has the effect of synchronously treating various mine wastewater, neutralizing and circulating treatment is carried out on acidity and alkalinity, multiple treatment is carried out on domestic water and the like, the purpose of recycling is finally achieved, environmental protection is improved, and waste of water resources is reduced.

Description

technical field [0001] The invention relates to the technical field of waste water circulation treatment, in particular to a mine waste water circulation treatment system. Background technique [0002] The mining industry has always been the pillar industry of our country's economy and has made outstanding contributions to the development of the national economy. However, the mine wastewater produced has also caused serious damage to groundwater resources and the surrounding environment. There are many types of mining sewage, which can be roughly divided into: 1. Domestic sewage, which is mainly produced by the construction workers in the mining area; 2. Ordinary mine water. The hardness and salinity of this type of wastewater are not high, and the water quality is neutral. The internal suspended matter is mainly particles such as rock dust; 3. High salinity mine water, the water body of this type of waste water has high hardness, contains inorganic salts inside, and is neut...
