1. Overview:

Coal mine mining water is affected by coal gangue

2.2 Process selection

2.2.1Process selection

The latest patented equipment "Magnetic Separation Coal Mine Wastewater Treatment Plant" is used as the main equipment to treat the wastewater. This equipment integrates multiple functions such as drug feeding, flocculation reaction, mud water separation, water purification, sludge concentration and dewatering (has obtained national patent number: ZL2013 2 0598273.1）。 Mainly used for sewage and wastewater treatmentoneGrade physical and chemical enhanced mixingCondensation treatment, can quickly（3Efficient removal of suspended solids, turbidity reduction, decolorization, viscosity reduction, and clear water quality within minutes, effectively reducing organic matter in water. It can also be used for phosphorus removal, algae removal, hard water softening, and concentration dewatering of sludge containing wastewater. It can replace air flotation or sedimentation tanks in water treatment projects and is a revolutionary alternative to traditional treatment methods.

The main components of the "magnetic separation coal mine sewage treatment machine" are composed of various devices such as a mixing and flocculation reactor, a mud water separator, a clear water overflow device, and a sludge concentration and pressing dewatering device. The sewage enters the machine, and various water treatment agents are automatically metered and injected into the sewage in sequence. Impurities in the sewage undergo coagulation reaction to produce flocs. At this time, turbid (or colored) sewage becomes clear due to solid-liquid separation. Then the sewage enters a specific high-energy physical field, and with its strong energy field adsorption force, the flocs in the water are instantly adsorbed and removed. After removing impurities and flocs, the clean water flows out from the water pipe, and the remaining flocs are compressed and concentrated into mud, which slides out of the machine.

2.2.2Significant advantages of this device

(1)Fast processing speed: The dwell time inside the machine is ≤ 3 minutes.

(2)Small overall area: 100m³/H occupies an area of ≤ 25m².

(3)Energy saving: The electricity consumption per ton of water treatment is ≤ 1.5Kw.

(4)High purification degree of effluent: SS removal rate>90%. Remove viscosity>99%

(5)High degree of sludge drying: solid content ≥ 20%.

(6)Low noise:<60 decibels.

(7)No need for backwashing, stable and reliable automatic operation.

(8)It can greatly save equipment maintenance and repair costs, as well as various expenses such as technical personnel and operators.

(9)It can replace air flotation or sedimentation tanks in water treatment projects and is a revolutionary alternative to traditional treatment methods.

3.3.1、Process description:

Wastewater flows into the regulating tank, which not only regulates the water volume but also homogenizes the water quality. The wastewater pump lifts the wastewater toThe "magnetic separation sewage treatment equipment" uses an automatic dosing device to add various chemicals and fully mix the wastewater in the reactor. A mixer is used to mix and stabilize the wastewater. SS and most COD in the water precipitate in the form of particles and coagulate into flocs. The flocs are wrapped with specific sensitive substances, and then the wastewater enters a specific high-energy physical field. With its strong energy field adsorption force, the flocs in the water are instantly adsorbed and removed. The remaining flocs are compressed and concentrated into mud, which is then slid out of the integrated machine. After removing impurities and flocs, the clean water flows out of the water pipe and enters the clean water tank for reuse.
