Description

Technical Field

[0001] The present invention relates to the field of chemical wastewater treatment, and in particular to an environmentally friendly chemical wastewater treatment system and a treatment method. Background Art

[0002] Wastewater treatment is an indispensable part of modern industry and life. In order to effectively remove suspended matter in wastewater, physical treatment methods are widely used in the prior art, among which flotation is a common and effective method. Flotation uses the floating effect of bubbles to bring suspended matter in wastewater to the surface of the water body, thereby achieving solid-liquid separation.

[0003] In the traditional flotation method, bubbles are generated by a bubble generator and evenly distributed on the bottom of the pool, and then float up from the bottom. This bubble distribution method has many disadvantages:

[0004] In the traditional flotation method, the direction of the bubbles is fixed. This regular flotation method easily forms dead corners, resulting in some suspended matter being unable to fully contact with the bubbles, reducing the flotation effect.

[0005] Although the bubble generators are evenly distributed at the bottom of the pool, in actual operation, the distribution and size of the bubbles may be affected by many factors, resulting in uneven floating of the bubbles, thus affecting the treatment effect.

[0006] When the suspended matter floats to the top of the liquid surface, a rotary scraper is usually required to remove the floating suspended matter. The rotary scraper in the prior art has the following main shortcomings:

[0007] Rotary scraping can usually only scrape from one direction to another, such as circular scraping or horizontal scraping. This single-direction scraping method is inefficient when the stroke is large and is prone to uneven scraping;

[0008] The scraping process needs to cover the entire water surface. When the water surface area is large, the scraping device needs to run for a long time to complete one scraping, resulting in low processing efficiency;

[0009] In order to achieve effective scraping, traditional rotary scrapers usually require complex mechanical structures, which not only increases the manufacturing cost of the equipment, but also increases the maintenance difficulty and operating cost. Summary of the invention

[0010] In order to solve the above problems, the present invention provides an environmentally friendly treatment system and method for chemical wastewater, which adopts a circular expansion method to evenly push suspended matter outward and form a closed cavity to absorb the suspended matter. This all-round synchronous expansion scraping method can greatly improve the scraping efficiency and make the scraping more uniform. In addition, the present invention adopts a twisting method to control the direction of the bubble discharge port, so that the bubbles can be distributed throughout the entire treatment pool and in all directions. The discharge direction of the bubbles is no longer a single vertical upward direction, so the contact area with the suspended matter can be effectively increased, the flotation efficiency can be improved, and the deficiencies in the prior art can be effectively solved.

[0027] A method for environmentally friendly treatment of chemical wastewater of the present invention comprises the following steps:

[0028] Step 1: Put the chemical wastewater to be treated into the treatment tank to the set liquid level, and then turn on the bubble generator. At this time, the elastic scraper ring does not contact the upper end surface liquid level of the wastewater, and the bubbles generated by the bubble generator carry the suspended matter up to the liquid surface;

[0029] Step 2, start the driving motor, the driving motor drives the rotating disk to rotate, when the rotating disk rotates, it drives each air flotation hose to twist, when the air flotation hose twists, the discharge direction of each bubble discharge port changes to any direction, and each air flotation hose twists and pulls down the fixed disk and the elastic scraper ring, and makes the elastic scraper ring contact with the upper end surface of the liquid surface;

[0030] Step 3: At this time, the air pump is turned on, the solenoid valve is closed, and the air pump is turned on to inject air into each second telescopic connecting pipe, thereby pushing the second telescopic connecting rod out of the second telescopic sleeve.

[0035] Second, after the air flotation hose of the present invention is twisted, the distance between the rotating disk and the fixed disk becomes shorter, so that the first telescopic connecting tube can be pulled, so that the elastic scraper ring that was not in contact with the liquid surface originally descends and contacts the liquid surface, so that the elastic scraper ring can be expanded in a ring-shaped manner by using an air pump to scrape the suspended matter on the liquid surface uniformly in the circumferential direction synchronously, which greatly improves the efficiency and makes the scraping more uniform;

[0036] And only need to reset the air flotation hose, can reset the elastic scraper ring, so that the elastic scraper ring rises again away from the liquid surface, and then reset the elastic scraper ring, so that the reset of the elastic scraper ring does not contact the liquid surface. The present invention uses the torsional action of the air flotation hose to control the contact and separation of the elastic scraper ring and the liquid surface, which greatly simplifies the structure. At the same time, the air flotation hose can enjoy the bubble discharge mode in different directions due to the torsional action. The structural design is more reasonable, and the influence of the reset contraction of the elastic scraper ring on the scraper is effectively avoided.
