Description

Technical Field

[0001] The invention belongs to the technical field of industrial wastewater treatment, and particularly relates to a quartz sand pickling wastewater rapid treatment device and a treatment process thereof. Background Art

[0002] In the production of ultra-pure quartz sand, hydrofluoric acid (HF) pickling can effectively remove metal and mineral impurities, but it will produce pickling wastewater with complex components. The pickling wastewater mainly contains HF, medium metal ions, fluoride (F-), suspended matter and silicon compounds. Among them, fluoride (F-) is highly toxic, and direct discharge will seriously pollute the environment and endanger human health;

[0003] The discharge standard of ultrapure quartz sand pickling wastewater is mainly based on the "Comprehensive Wastewater Discharge Standard" (GB 8978-1996); "Inorganic Chemical Industry Pollutant Discharge Standard" (GB 31573-2015) and relevant local standards or industry standards. The following are some key control indicators and emission requirements: pH value 6-9, suspended solids ≤50mg / L, heavy metal ions ≤0.1mg / L, fluoride ≤10mg / L.

[0004] After searching, the prior art announcement number is: CN117326756A. A treatment process for high-purity quartz sand pickling wastewater includes the following steps: S1. The high-purity quartz sand pickling wastewater is discharged into a raw water pool and allowed to stand; S2. The wastewater is pumped to a neutralization pool, and lime water is added to adjust the pH of the wastewater in the pool to 6.0-7.0; S3. The neutralized wastewater is transported to a coagulation sedimentation pool, calcium chloride and PAC are added, coagulated and stirred, allowed to stand and precipitate, and the sludge is discharged to a sludge pool after precipitation; S4. The coagulation sedimentation supernatant is discharged to an ion adsorption pool, stirring is started, and adsorbent calcium aluminum hydrotalcite is added to the pool for adsorption, and the fluoride ion content is measured until the fluoride ion content is lower than 5 mg / L, stirring and adsorption are stopped, and the water quality meets the standard and is discharged to a discharge pool;

[0005] Further search, the prior art announcement number: CN117735693A A kind of ultra-pure quartz sand pickling wastewater treatment device and treatment method thereof, including a waste liquid collection component, a stirring component, a reagent adding component and a waste gas treatment component; the waste liquid collection component includes a collection tank, an inflow pipe and an air intake pipe; the stirring component includes a stirring motor, a stirring shaft, a bearing and a blade; the reagent adding component includes a reagent barrel, a meter and a reagent adding pipe; the waste gas treatment component includes a neutralization tank, a neutralization liquid, a waste gas discharge pipe and an exhalation pipe; although the prior art adds a sodium-containing reagent to make the harmful substance fluorosilicic acid in the pickling wastewater react with the sodium-containing reagent to form sodium fluorosilicate crystals, it does not treat other components of the ultra-pure quartz sand pickling wastewater, resulting in incomplete wastewater treatment, and unable to achieve comprehensive purification and resource utilization;

[0006] After another search, the prior art announcement number is: CN118811902A. A quartz sand purification wastewater secondary utilization treatment equipment is arranged on a quartz sand purification production line for supporting use. The quartz sand purification production line is composed of quartz sand ore subjected to ball milling, ore washing, magnetic separation, flotation, pickling and heat treatment processes, including a mud water settling tank, a recycling pipeline system, a magnetic separation mechanism and a pickling equipment, wherein the mud water settling tank is used to settling the ore washing wastewater after ore washing; although the prior art realizes the recycling and reuse of the purified waste products, it does not treat the fluoride (F-) in the quartz sand pickling wastewater, thereby causing serious pollution to the water body, soil and ecological environment, and even endangering human health. Summary of the invention

[0007] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a quartz sand pickling wastewater rapid treatment device and a treatment process thereof. The pickling wastewater and the neutralizing agent are stirred by a dosing mechanism to preliminarily mix the pickling wastewater and the neutralizing agent; the neutralization flocculation mechanism ensures that the pickling wastewater is neutralized while harmful substances such as metal ions and fluoride ions in the wastewater are rapidly flocculated into agglomerates and precipitates are generated, and the pickling wastewater and the precipitate are quickly separated; the mixing tube and inclined plate sedimentation mechanism are used to further remove harmful substances in the pickling wastewater, thereby realizing efficient treatment of the pickling wastewater.

[0008] In order to achieve the above object, the technical solution adopted by the present invention is:

[0009] 1) Neutralization treatment: When the pickling wastewater enters the neutralization flocculation mechanism, the dosing mechanism adds the neutralizing agent into the pickling wastewater, and the motor IV in the dosing mechanism drives the telescopic medicine tube to rotate, so that the telescopic medicine tube rotates, and the stirring blades at the telescopic end of the telescopic medicine tube rotate; the electric push rod pushes the telescopic end of the telescopic medicine tube to move up and down, and the stirring plates hinged on both sides of the telescopic end of the telescopic medicine tube swing flexibly under the action of the tension spring, and rotate synchronously with the telescopic medicine tube, so that the pickling wastewater and the neutralizing agent are preliminarily mixed, and the pH of the neutralized pickling wastewater is adjusted to 6.0-7.5;

[0010] 2) Flocculation treatment: After the pickling wastewater and the neutralizing agent are preliminarily mixed in the neutralizing flocculation mechanism, the flocculant is added to the pickling wastewater in the neutralizing flocculation mechanism;

[0011] 3) Mixing treatment: After neutralizing agent and flocculant are added to the pickling wastewater, the motor I in the neutralizing and flocculating mechanism drives the rotating tube to rotate, and the gear ring I on the rotating tube cooperates with the internal teeth on the inner wall of the stirring barrel to drive the two sets of gears II to rotate, thereby driving the stirring frame to rotate stably in the sliding groove at the bottom of the stirring barrel at a stirring rate of 600r / min, and strongly stirring the pickling wastewater for 15-20min to accelerate the reaction speed of the pickling wastewater with the neutralizing agent and flocculant; the operation of motor II drives the reciprocating screw I to rotate, driving the sliding frame to slide back and forth along the sliding rod I, and the spoiler frame moves up and down driven by the sliding frame while continuously rotating under the cooperation of the rack and gear III, further disrupting the water flow, so that the pickling wastewater, the neutralizing agent and the flocculant are fully mixed and reacted to generate a large amount of precipitation;

[0012] 4) Separation and precipitation: After the stirring is completed, the generated precipitation enters the filter barrel together with the pickling wastewater. The precipitation is separated from the pickling wastewater under the action of the annular inclined plate with an inclination angle of 60° and its own gravity. The filter plate with a pore size of 50μm further filters the pickling wastewater to prevent the precipitation that is not separated from the pickling wastewater from entering the mixing tube;

[0013] 5) Adsorption treatment: inject the adsorbent into the mixing tube and fully mix it with the pickling wastewater entering the mixing tube for 20-25 minutes;

[0014] 6) Discharge up to standard: After the pickling wastewater is fully mixed with the adsorbent, it flows in the inclined plate.

[0044] Example 1

[0045] The treatment process steps of a quartz sand pickling wastewater rapid treatment device are as follows:

[0046] 1) Neutralization treatment: When the pickling wastewater enters the neutralization flocculation mechanism, the dosing mechanism adds the neutralizing agent into the pickling wastewater. The main component of the neutralizing agent is sodium hydroxide, and the dosage is 300 mg / L. The motor IV in the dosing mechanism drives the telescopic medicine tube to rotate, so that the telescopic medicine tube rotates, and the stirring blades at the telescopic end of the telescopic medicine tube rotate; the electric push rod pushes the telescopic end of the telescopic medicine tube to move up and down, and the stirring plates hinged on both sides of the telescopic end of the telescopic medicine tube swing flexibly under the action of the tension spring, and rotate synchronously with the telescopic medicine tube to preliminarily mix the pickling wastewater with the neutralizing agent;

[0047] 2) Flocculation treatment: After the pickling wastewater and the neutralizing agent are preliminarily mixed in the neutralizing flocculation mechanism, the flocculant is added to the pickling wastewater in the neutralizing flocculation mechanism. The flocculants are mainly calcium chloride and PAC. The dosages of calcium chloride and PAC are 150 mg / L and 50 mg / L respectively.

[0048] 3) Mixing treatment: After the neutralizing agent and flocculant are added to the pickling wastewater, the motor I in the neutralizing and flocculating mechanism drives the rotating tube to rotate, and the gear ring I on the rotating tube cooperates with the internal teeth on the inner wall of the stirring barrel to drive the two sets of gears II to rotate, thereby driving the stirring frame to rotate stably in the sliding groove at the bottom of the stirring barrel at a stirring rate of 600r / min, and strongly stirring the pickling wastewater for 25 minutes to accelerate the reaction speed of the pickling wastewater with the neutralizing agent and flocculant; the operation of motor II drives the reciprocating screw I to rotate, driving the sliding frame to slide back and forth along the sliding rod I, and the spoiler frame moves up and down under the drive of the sliding frame while continuously rotating under the cooperation of the rack and gear III, further disrupting the water flow, so that the pickling wastewater, the neutralizing agent and the flocculant are fully mixed and reacted to generate a large amount of precipitation;

[0049] 4) Separation and precipitation: After the stirring is completed, the generated precipitation enters the filter barrel together with the pickling wastewater.

[0060] It can be seen from the above description that: the pickling wastewater enters the rotating tube 24 through the water inlet 105 at one end of the fixed tube 25, and flows into the stirring barrel 23 from the top of the rotating tube 24. When the pickling wastewater is in the rotating tube 24, the dosing mechanism 3 adds a neutralizing agent to the pickling wastewater, and preliminarily blends the pickling wastewater and the neutralizing agent; while the pickling wastewater flows into the stirring barrel 23, the flocculant is added to the stirring barrel 23 through the nozzle Ⅰ2802 at the top of the annular medicine tube 28; at the same time, the motor Ⅰ26 is started to drive the rotating tube 24 to rotate, and the gear ring Ⅰ2305 on the rotating tube 24 cooperates with the internal teeth 2304 on the inner wall of the stirring barrel 23 to drive the two sets of gears Ⅱ2307 to rotate, thereby driving the stirring frame 2308 to stably rotate in the sliding groove 2316 at the bottom of the stirring barrel 23, and strongly stirs the pickling wastewater to accelerate the reaction speed of the pickling wastewater with the neutralizing agent and the flocculant;

In this process, the pickling wastewater is fully neutralized, and the metal ions, fluoride ions, suspended matter and silicon compounds in the wastewater are The flocculation of the pickling wastewater produces a large amount of precipitation; the produced precipitation flows out through the water outlet 2301 at the top of the stirring barrel 23 together with the pickling wastewater and flows into the bottom of the sedimentation barrel 21 along the outer wall of the filter barrel 22, and then enters the filter barrel 22 from the bottom of the sedimentation barrel 21. The precipitation in the pickling wastewater is separated from the pickling wastewater under the action of the annular inclined plate 2201 and its own gravity, and settles to the bottom of the sedimentation barrel 21. The filter plate 2202 further filters the pickling wastewater to prevent the precipitation that is not separated from the pickling wastewater from entering the mixing tube 4;
