Description

Technical Field

[0001] The utility model relates to the field of formaldehyde wastewater, in particular to a formaldehyde wastewater treatment device capable of preventing filter screen from being clogged. Background Art

[0002] Formaldehyde wastewater mainly comes from multiple links in industrial production, including organic synthesis, synthetic fibers, dyes, plastics, leather making, wood processing and paint making industries. Specifically, the wood processing industry produces formaldehyde-containing wastewater when using formaldehyde-containing adhesives such as urea-formaldehyde resin, such as in the manufacture of artificial boards. Formaldehyde wastewater treatment equipment usually uses physical, chemical or biological methods to decompose the formaldehyde in the wastewater into harmless substances. These methods have their own characteristics and can be selected based on comprehensive consideration of factors such as the composition, concentration and emission volume of the wastewater.

[0003] After searching, a wastewater treatment device for chlorobenzaldehyde production with the announcement number CN217613177U was found, which specifically discloses a wastewater treatment device for chlorobenzaldehyde production. The two ends of the treatment box are respectively provided with an inlet pipe and an outlet pipe, the outer surface of the sewage pipe is provided with a valve, the interior of the filter tank is provided with a fixed block, the upper surface of the treatment box is provided with a box cover, and one side of the box cover is provided with a limiting mechanism. The dosing mechanism includes a dosing port, which is opened inside the box cover, and a movable groove is opened on one side of the dosing port. A baffle is provided inside the movable groove, and the dosing port and the baffle play the role of dosing. This wastewater treatment device for chlorobenzaldehyde production is convenient for replacing the filter layer, and the movable baffle facilitates dosing, and the precipitate can be discharged by rotating the valve.

[0004] During use, the existing formaldehyde wastewater treatment device has a filter, which is an important component of the wastewater treatment device. Its function is to intercept and remove impurities such as suspended matter and particulate matter in the wastewater. Once the filter is clogged, the flow rate of the wastewater will be seriously affected, resulting in a decrease in treatment efficiency. This will not only prolong the wastewater treatment time, but also make it impossible for the wastewater to meet the discharge standards within the specified time. The formaldehyde wastewater treatment device in the above-mentioned comparative case also lacks the ability to prevent the filter from being clogged. Under long-term use, the formaldehyde wastewater treatment device will malfunction or be damaged due to excessive pressure, and needs to be replaced or repaired, further increasing the cost of wastewater treatment.

[0005] Therefore, it is necessary to invent a formaldehyde wastewater treatment device that prevents filter screen clogging to solve the above problems. Utility Model Content

[0006] The utility model aims to provide a formaldehyde wastewater treatment device which can prevent filter clogging. The formaldehyde wastewater treatment device has the ability to prevent filter clogging through the water inlet treatment port, the inlet filter basket, the filter scraper, the first formaldehyde wastewater filter, the second formaldehyde wastewater filter, the flushing cavity and the flushing nozzle. The formaldehyde wastewater treatment device can ensure the smooth flow of wastewater in the device, thereby improving the efficiency of wastewater treatment. Moreover, keeping the filter unobstructed can ensure that impurities and particulate matter in the wastewater are effectively removed, thereby improving the effluent water quality and making it more in line with the emission standards. Preventing filter clogging can enhance the stability of the entire wastewater treatment device, reduce the shutdown or malfunction caused by filter clogging, and further reduce the wastewater treatment. The cost effect is to solve the problem that the formaldehyde wastewater treatment device in the prior art is in use. Since the filter is an important component of the wastewater treatment device, its function is to intercept and remove impurities such as suspended matter and particulate matter in the wastewater. Once the filter is clogged, the flow rate of the wastewater will be seriously affected, resulting in a decrease in treatment efficiency, which will not only prolong the wastewater treatment time, but also make the wastewater unable to meet the emission standards within the prescribed time. Moreover, the formaldehyde wastewater treatment device in the above-mentioned comparative case also lacks the ability to prevent the filter from being clogged. Under long-term use, the formaldehyde wastewater treatment device will malfunction or be damaged due to excessive pressure and needs to be replaced or repaired, further increasing the cost of wastewater treatment.
