Sewage treatment equipment > Zl - mkws001 coal mine wastewater treatment equipment
Mine wastewater treatment equipment using physical and chemical methods, the sewage in the suspended particles, metal ions, nonmetal pollutants removal, in order to achieve the purpose of purifying water quality.Equipment basic structure is the combination of carbon steel anticorrosive processing components.Can according to customer's actual situation to install or the scene splicing combination as a whole.Light weight, easy to transport, convenient installation, corrosion resistance, long life and other characteristics;A high degree of automation equipment, low energy consumption, small management cost;Purification efficiency is high, the SS removal rate over 93%, water the indicators meet the national "integrated wastewater discharge standard" (GB 8978-1996), the level of standards, emissions can be up to standard.
Name: coal mine wastewater treatment equipment
Model: zl - mkws001
Power: 1.1. (kw)
Sewage quantity: 10 (m3 / h)
Processing custom, can according to customer requirements for manufacturing
General mine wastewater with chemical method, according to the water quality situation, if COD on the high side, but behind the physico-chemical process and biological treatment process to deal with.
Technology commonly used are: regulating pool + tank + filtration + coagulation reaction pool
Or: adjusting pool + coagulation reaction pool, primary sedimentation tank + filtration + aerobic + secondary precipitation
The mine wastewater quality analysis:
There were significant differences in different coal mine water quality, the water quality and common water quality of surface water and groundwater have obvious differences, has obvious characteristics of the coal industry, mainly include:
1. The suspended solids content of coal mine water was obviously higher than that of surface water, and is not very stable, sensory properties.
2. The suspended matter small size, light weight, slow subsidence, the mine water suspended particles diameter smaller, on average only 2 ~ 8 um, about more than 85% of the total suspended solids under 50 um particle size;The average density of pulverized coal is normally 1.3 ~ 1.6 g/cm3, significantly less than the clay sand particles in surface water of the average density of 1.9 ~ 62.6 g/cm3.
3. Containing organic pollutants.Surface water is generally not contain organic matter, and in the mine water, in addition to the pulverized coal is organic matter, water also contains a small amount of waste oil, emulsified oil, rotting waste timber, such as underground waste organic matter.
4. Difficult alum flowers in the process of coagulation, sedimentation effect is poor.
5. Pulverized coal mine water as the suspended solids, only not oxygen organic pollutants.Different containing suspended solids mine water CODcr difference is big, but the CODcr is due to organic carbon reducibility in slack, so the general need for biochemical treatment.
1. The coagulation sedimentation tank, settling tank size
2. The filter specifications
Of the packing is commonly within medium filter: quartz sand, granular activated carbon, anthracite, KDF, porous ceramic particles, etc., can choose according to actual needs to use.Within the water flow through the filter packing to intercept to remove the suspended solids in the water, organic matter, colloid particles, microorganism, oxygen ions, mainly for the domestic water, industrial water supply, water reuse.Fill in fluoride in filter material in filter activated alumina, remove the fluoride in water.Fill in sponge iron in filter, remove the oxygen.
