Description

Technical Field

[0001] The invention belongs to the technical field of environmental engineering, and in particular relates to an environmental engineering water treatment system. Background Art

[0002] Wastewater treatment is a crucial component of environmental engineering. Sewage treatment plants effectively treat urban domestic and industrial wastewater, preventing wastewater and pollutants from flowing directly into waterways. This plays a crucial role in improving the ecological environment, enhancing urban quality, and promoting economic development. Sewage treatment plants used in environmental engineering typically utilize biofilms for wastewater purification. However, over time, the biofilms are susceptible to stains, resulting in poor purification performance and ultimately impacting the effectiveness of the biofilms.

[0003] Existing methods for cleaning biofilms generally use backwashing. However, existing backwashing can only clean the biofilm from the back by applying pressure. Although the stains attached to the front of the biofilm are washed away, the free stains will still quickly adhere to the biofilm, resulting in poor cleaning effect and affecting the purification effect of sewage. To this end, we provide an environmental engineering water treatment system to solve the above problems. Summary of the Invention

Through the coordinated use of a backwash component, an adsorption component and a pressurizing component, not only the flushing of the biofilm is completed, but also the stains attached to the biofilm are removed and sucked out for cleaning, avoiding the floating stains from being adsorbed on the biofilm again, thereby improving the service life of the biofilm and the purification effect of sewage, and solving the problem that the existing biofilm cleaning method generally adopts a backwashing method, but the existing backwashing can only achieve the cleaning of the biofilm by pressurizing from the back, but although the stains attached to the front of the biofilm are washed away, the free stains will still quickly attach to the biofilm, resulting in poor cleaning effect, and thus affecting the purification effect of sewage.

DETAILED DESCRIPTION

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0032] For example 1, please refer to Figure 1-11 The present invention provides the following technical solutions: a water treatment system for environmental engineering, comprising a purification component 1; the purification component 1 comprises a box body 101, and a biofilm 102 is fixedly connected to the inner circumferential side surface of the box body 101; a backwash component 2 is fixedly fitted inside the box body 101, and the backwash component 2 comprises a flushing cover 201 that fits with the bottom of the biofilm 102, and a plurality of through holes 202 distributed in a circular array are opened at the bottom of the flushing cover 201, which deviates from the center of the circle, and a positioning groove 203 corresponding to the plurality of through holes 202 is opened at the bottom of the flushing cover 201, which deviates from the center of the circle.

[0033] The outer wall of the box body 101 is fixedly connected with a U-shaped tube 204, which is connected to the flushing cover 201. The outer wall of the U-shaped tube 204 is connected with an air inlet pipe 205, and the air inlet pipe 205 is provided with a solenoid valve 206; the outer wall of the U-shaped tube 204 is slidably matched with a blocking component 3 for blocking a plurality of through holes 202, and the outer top of the box body 101 is slidably matched with an adsorption component 4, which includes a cylindrical tube 401 that is slidably connected to the outer top of the box body 101, and the inner circumferential side of the cylindrical tube 401 is slidably matched with a sleeve 402 ( A hole is opened through the outer wall of the sleeve 402, so that the water inside the sealing cover 403 can enter the sleeve 402 through the hole, thereby ensuring that the subsequent suction is carried out smoothly), the outer peripheral side of the cylindrical tube 401 is fixedly connected to the sealing cover 403, and the outer peripheral side of the sleeve 402 is fixedly connected to the scraper 404 that is in sliding contact with the biofilm 102; the inner peripheral side of the U-shaped tube 204 is slidably matched with the pressure component 5, and the pressure component 5 includes a pressure plate 501 that is slidably connected to the inner peripheral side of the U-shaped tube 204, and the top of the pressure plate 501 is fixedly connected to the extension rod 502.

[0034] The operation process of this embodiment is as follows: first, the air inlet pipe 205 is controlled to be in a closed state by controlling the solenoid valve 206, and then the cylindrical tube 401 is connected to the external pump output end, and then the cylindrical tube 401 is controlled to move downward, and at the same time, the cylindrical tube 401 is controlled to rotate (in the initial state, the pressure plate 501 is not in contact with the water inside the U-shaped tube 204), so that the sealing cover 403 on the cylindrical tube 401 is attached to the upper surface of the biofilm 102, and at the same time, the sleeve 402 is in contact with the top of the biofilm 102. As the cylindrical tube 401 rotates, the sleeve 402 is driven to rotate, and further the scraper 404 is driven to rotate, so that the scraper 404 scrapes the stains stuck on the biofilm 102, so that the stains are removed. In the free state, the external water pump is then started, so that the sewage and stains inside the sealing cover 403 are sucked to the outside of the box body 101. At the same time, the extension rod 502 is controlled to drive the pressure plate 501 to move downward, so that the pressure plate 501 pushes the water inside the U-shaped tube 204 to move into the flushing cover 201. By continuously pressurizing the water inside the flushing cover 201 (before this, the through hole 202 is blocked by the blocking component 3, so that a closed space is formed between the flushing cover 201 and the biofilm 102), the biofilm 102 is backwashed, and then the biofilm 102 is cleaned, which effectively improves the service life of the biofilm and the purification effect of the sewage.

A number of support rods 304 are fixedly connected to the top of the annular plate 303, and a sealing plate 305 corresponding to the positioning groove 203 is fixedly connected to the top of the support rod 304. The outer wall of the annular plate 303 is symmetrically fixedly connected with two slides 306 that slide with the first sliding groove 108, and the bottom of one of the connecting plates 302 is fixedly connected to a push rod 307 that contacts the wedge block 106.

[0036] The operation process of this embodiment is: by controlling the electric push rod 104 to drive the cross bar 105 and the wedge block 106 to move the rod toward the push rod 307, so that the wedge block 105 conflicts with the push rod 307, and then drives the push rod 307 to move upward, and then drives the blocking plate 305 to move upward through the connecting plate 302 and the annular plate 303, so that the blocking plate 305 is correspondingly plugged into the positioning groove 203, thereby completing the blocking of the through hole 202.
