Description

Acidic wastewater treatment device and method

Technical Field

The invention relates to the technical field of wastewater treatment, and in particular to acidic wastewater treatment equipment and method.

Background technique

Acidic wastewater refers to wastewater containing certain acids and with a pH value lower than 6. Acidic and alkaline wastewater entering the water body will destroy the natural neutralization effect, change the pH value of the water body, affect the normal growth of aquatic organisms, and reduce the self-purification function of the water body. Acidic and alkaline wastewater seeps into the soil, which will destroy the physical and chemical properties of the soil, causing soil acidification or alkalization, affecting the normal growth of crops. Acidic wastewater mainly comes from wastewater discharged during the production process of industrial sectors such as mine drainage, hydrometallurgy, steel rolling, steel and non-ferrous metal surface acid treatment, chemical industry, acid making, pharmaceuticals, dyes, electrolysis, electroplating, and artificial fibers. Acidic wastewater needs to be treated before it can be discharged, so the acidic wastewater treatment equipment and method are needed.

For example, an acid wastewater treatment device and treatment method with patent publication number CN107673539A is composed of a dearsenicization system, an evaporation concentration system, a stripping system and a reverse osmosis system. In order to solve the deficiencies of the prior art, a device and a treatment method for efficiently treating acid wastewater generated in the process of smelting flue gas acid production are provided. Since lime milk is not added during the treatment process, the water obtained after treatment by the device and method of the present invention can be returned to the smelting flue gas acid production system for reuse, saving water resources.

However, during the acidic wastewater treatment process, the above-mentioned equipment needs to be left to settle to remove suspended matter and impurities in the wastewater due to the internal arsenic removal system and reverse osmosis system. However, the sedimentation time is relatively long. Long-term sedimentation may also cause certain harmful substances in the wastewater to undergo chemical reactions during the sedimentation process to generate new pollutants, thereby reducing work efficiency. At the same time, a large amount of neutralization sludge will be produced during the neutralization reaction of the acidic wastewater. The sludge is not only bulky, but also easily adheres to the equipment and clogs the equipment. Therefore, in response to this situation, we propose a more convenient and practical acidic wastewater treatment equipment that meets the use needs.

When the sedimentation inclined plate 504 needs to be replaced, the baffle 505 is manually opened and the push rod 503 is pulled to remove the sedimentation inclined plate 504 under the action of the fixed frame 502. When sludge appears at the base of the box 501, the stepper motor 509 drives the screw rod 506 to rotate, driving the sliding block 507 and the scraper 508 to push the sludge into the sedimentation funnel 510 and into the sludge pipe 511.

The first driven bevel gear 305 drives the rotating tube 304 and the first stirring plate 308 to rotate, and the second driven bevel gear 307 drives the first rotating rod 306 and the second stirring plate 309 to rotate.

A method for treating acidic wastewater, using the above-mentioned acidic wastewater treatment equipment, comprises:

Step 1: Feeding and pretreatment: wastewater enters the equipment through the feeding mechanism 1, and the feeding mechanism 1 cooperates with the spraying mechanism 2 and the stirring mechanism 3 to mix the wastewater with the treatment agent. The spraying mechanism 2 sprays the treatment agent into the wastewater in a cross-even manner in a pulse manner through the booster pump 204 and the spray pipe 206. The stirring mechanism 3 drives the stirring plate to rotate through the servo motor 303 and the bevel gear to fully mix the wastewater and the treatment agent to improve the reaction efficiency;

Step 2: Heating treatment: The heater 4 connected to the bottom of the housing 101 heats the wastewater to increase the solubility of pollutants in the wastewater or accelerate the chemical reaction rate;

Step 3: Sedimentation and solid-liquid separation: After the reaction and neutralization, the wastewater enters the box 501 and passes through the sedimentation inclined plate 504 to form a sedimentation environment, so that the solid particles or suspended matter in the wastewater can be quickly precipitated. The precipitated sludge can be discharged through the sludge pipe 511, and the clear liquid is further filtered;

Step 4: Filtration and purification: The clear liquid is further filtered and purified through the filtering mechanism 6. In this process, the filter cartridge 602 effectively removes tiny particles and suspended matter in the wastewater, improves the water quality, and automatically cleans the filter cartridge 602.

It should be noted that during use, first, waste water enters the first connecting pipe 102 through the first water inlet pipe 103, and is input into the housing 101 through the fixed pipe 104 and the first nozzle 105. The treatment agent enters the liquid storage tank 201 through the feed pipe 202, and the booster pump 204 starts to effectively extract the treatment agent from the liquid storage tank 201, and transports it to the spray pipe 206 through the drain pipe 203 and the second connecting pipe 205, and sprays it out from the second nozzle 207. When the treatment agent is mixed, the servo motor 303 on the mounting frame 301 is first started, driving the driving bevel gear 302 to rotate, while the first driven bevel gear 305 drives the rotating tube 304 and the first stirring plate 308 to rotate, and the second driven bevel gear 307 rotates through the first rotating rod 306 and the second stirring plate 309, and is heated by the heater 4. When the wastewater and the treatment agent are fully mixed in the housing 101, the solenoid valve 107 is opened, so that the mixed wastewater is smoothly discharged into the first drain pipe 106. In the sedimentation mechanism 5, the first sedimentation is carried out through the sedimentation inclined plate 504. When sludge appears at the base of the box body 501, the stepper motor 509 drives the screw rod 506 to rotate and drives the sliding block 507 and the scraper 508 to push the sludge into the sedimentation funnel 510 and enter the sludge pipe 511. Then the reduction motor 514 drives the connecting rod 512 and the spiral plate 513 to rotate to discharge the sludge. The remaining wastewater enters the filter cartridge 602 through the second water inlet pipe 601 and is discharged through the second drain pipe 610. When the filter cartridge 602 needs to be cleaned, the cleaning motor 606 first drives the second rotating rod 603 to drive the fixed rod 604 and the brush 605 to rotate to clean the filter cartridge 602. After cleaning, the sludge enters the drain pipe 608 through the discharge funnel 607 and is manually opened and discharged by the second cover cap 609, which can increase the sedimentation area and improve the sedimentation efficiency. The precipitated sludge is discharged through the sludge pipe 511. The design of the spiral plate 513 facilitates the smooth discharge of the sludge and is highly practical.
