Integrated sewage treatment equipment for flocculation, pressure filtration and purification

The main components of mine wastewater are suspended solids and soluble inorganic substances, as well as small amounts of organic pollutants such as waste engine oil, emulsified oil, decaying waste pit wood, and underground feces. Mineral pollution includes sand, mud particles, mineral impurities, smoke, dissolved salts, acids, and alkalis; Organic compound pollution includes coal particles, oil, microbial life metabolites, wood, and oxidative decomposition products of other compounds. Due to the pollution caused by scattered fine ore, coal powder, rock powder and accompanying minerals during the mining and transportation process, the water quality is black gray, turbid, with floating oil on the surface, and emits a small amount of fishy and oily odor. The results of water quality monitoring and testing show that the chemical oxygen consumption is high, the total bacterial count and Salmonella content are high. If left untreated and discharged for a long time, it will have a certain negative impact on the environment.

Integrated sewage treatment equipment for flocculation, pressure filtration and purificationBy adopting the filter pressing process, the ultra-high pressure filter press integrates the functions of "traditional filter press+drying equipment". With a maximum pressure of 10Mpa, the water content of the coal slurry solid-liquid separation product is reduced by about 10% compared to traditional filter presses, and can be as low as 10.5%. This converts the coal slurry into directly usable power coal, significantly reducing the comprehensive investment cost of equipment and greatly improving the economic benefits and energy-saving and environmental protection indicators of the mining area.

Integrated sewage treatment equipment for flocculation, pressure filtration and purificationSix major advantages:

1. High squeezing pressure: The maximum squeezing pressure can reach 100 kilograms, which is 8-10 times that of traditional filter presses

2. High degree of automation: single person digital panel operation, all other processes are automatically controlled by PLC

3. Low investment cost: replacing the traditional filter press and drying processing mode, saving about 45% of investment

4. Large single device production capacity: The standard model has a daily production capacity of about 600 tons, an annual production capacity of 200000 tons, and a production cycle of 45 minutes

5. Low operating costs: only 20% compared to traditional modes

6. High dryness of coal slurry: The moisture content of the produced coal powder can be as low as 10.5%, meeting the coal demand of power plants
