Description

Mine sewage treatment equipment for removing heavy metal ions by using metal ion semipermeable membrane

Technical Field

The invention relates to the field of sewage treatment, in particular to mine sewage treatment equipment for removing heavy metal ions by using a metal ion semipermeable membrane.

Background

The semipermeable membrane is a membrane only allowing certain molecules or ions to diffuse in and out, and has selectivity for the passing of different particles, when the pressure of raw water at one side of the semipermeable membrane exceeds osmotic pressure by using a high-pressure pump, water molecules in the raw water can pass through the semipermeable membrane and enter the other side, and thus purified water is obtained. And the dissolved and non-dissolved inorganic salts, heavy metal ions, organic matters, thalli, colloid and other substances in the raw water can not pass through the semipermeable membrane and only can be left in the concentrated water to be discharged.

In the mining process, a large amount of heavy metal ions often exist in the sewage, the removal process is very complicated, a certain amount of heavy metal ions also exist in the discharged treated water, and the discharged treated water pollutes a water system.

The use steps herein are described in detail below with reference to fig. 1-4:

in the initial state, the meshing rack 38 is positioned at the uppermost side, the jacking rod 70 is positioned at the lowermost side, the fixed block 54 is positioned at the uppermost side, the jacking rod 44 is positioned at the rightmost side, the inflatable column 26 is not abutted by the fish expansion blocking block 31, the air bag 32 is in the contraction state, the partition plate 27 is positioned at the uppermost side, the floating block 45 is positioned at the lowermost side, the control valve in the drainage pipeline 25 is in the closing state, and the motor is in the standby state.

When sewage enters the water inlet pipeline 47 through the connecting hose 49, the sewage passes through the nano filter screen 73, so that an oil film is adsorbed, solid particles are blocked on the nano filter screen 73, the solid particles are accumulated on the nano filter screen 73 along with the time, the water inlet pipeline 47 is finally blocked, the water level rises in the water inlet pipeline 47, finally the water level rises and touches the detection block 48, an electric signal is sent to the rotating motor 60, the rotating motor 60 is started, so that the second partial gear 63, the first partial gear 62 and the filtering device rotating disc 71 rotate for a circle, in the process of the circle, the first partial gear 62 is firstly meshed with the pinion 58 to drive the reel 57 to rotate, the connecting rope 56 is released, so that the fixed block 54 descends under the action of the spring, then the first partial gear 62 is disengaged from the pinion 58, the reel 57 rotates reversely, and the fixed block 54 rises again, the sliding rod 55 is lifted and lowered to make the second rotating shaft 50 rotate for a circle, so that the first part of the gear 62 contacts the nano filter screen 73 at the lowest side, and the nano filter screen 73 falls through the pipeline, before the process, because the rotating shaft 61 rotates, the nano filter screen 73 in the water inlet pipeline 47 originally rotates to the filter material storage space 15 from the water inlet pipeline 47, at the moment, because the second part of the gear 63 rotates and is provided with part of the gear, the transverse rack 64 resets under the action of the spring after moving leftwards, the connecting rack 65 moves leftwards and rightwards, the jacking cam 69 resets after rotating ninety degrees forwards, the jacking rod 70 descends after rising, so that the nano filter screen 73 in the replacing space 14 is jacked up by the jacking rod 70 and falls to the lower side of the rotating replacing space 12, at the moment, the nano filter screen 73 in the replacing space 14 reaches the water inlet pipeline 47 before, and when the nano filter screen 73 is pushed away, the nano filter screen 73 just at the lowest side of the filter material storage space 15 falls down and is placed on the right side of the filter device turntable 71 for use.

After sewage enters the treatment space 19 through the water inlet pipeline 47, along with the rising of the water level, the floating block 45 rises until reaching the abutting induction block 75, at the moment, the partition plate 27 reaches the lowest side, at the moment, the inflation column 26 abuts against the telescopic blocking block 31, so that the inflation port in the locking block 29 is opened, at the moment, the air pump 24 is started to inflate the air bag 32, and the treatment space 19 is divided into the left side and the right side.

After the sewage reaches a certain amount, because the sewage at the left side and the right side both contain high-content heavy metal ions, the driving motor 40 is started at the moment, the main shaft 41, the second belt wheel 42 and the cam 43 rotate, the cam 43 rotates to enable the ejector rod 44 to continuously move left and right, so that the sewage at the right side of the treatment space 19 enters the first space 17 through the liquid inlet 33, then the sewage is extruded into the second space 18 and reaches the left side of the treatment space 19 through the liquid outlet 34, then the first incomplete gear 37 continuously rotates under the action of the belt 39 due to the rotation of the second belt wheel 42, so that the meshing rack 38 continuously ascends and descends, the sewage at the left side of the treatment space 19 is pressurized in the descending process, water molecules penetrate through the metal ion semi-permeable membrane 28 to enter the right side of the treatment space 19 due to the action of the metal ion semi-permeable membrane 28 after pressurization, and the concentration of the heavy metal ions, at this time, the sewage on the right side of the treatment space 19 is continuously pumped to the left side of the treatment space 19 for filtering, and once circulation is performed, so that the heavy metal ions in the water on the right side of the treatment space 19 reach a very low value, and the driving motor 40 is turned off after running for a period of time.

When the active motor 40 is turned off, the control valves in the water pump 23 and the water discharge pipeline 25 are started, so that the high-concentration heavy metal ion sewage on the left side of the treatment space 19 enters the high-concentration sewage storage space 22 to be further treated, and the treated water on the right side of the treatment space 19 is discharged through the water discharge pipeline 25.

The invention has the beneficial effects that: the invention relates to a device for treating mine mining sewage, which can filter the most oily substances and heavy metal ions in the mine sewage, treat an oil film in the sewage through a special nano oleophylic hydrophobic material, and simultaneously filter some solid particles.

The above embodiments are merely illustrative of the technical ideas and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the protection scope of the present invention.
