Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to an MBR wastewater treatment and greywater reuse device. Background Technology

[0002] The greywater reuse system is a wastewater treatment device, mainly used for the purification and reuse of industrial organic wastewater and domestic sewage. Its core adopts the PMW-B MBR integrated biological reactor system, which combines biological treatment technology and flat-plate membrane solid-liquid separation technology to replace the secondary sedimentation tank of the traditional activated sludge process, forming an integrated treatment process.

[0003] Existing MBR wastewater treatment devices, such as the integrated MBR wastewater treatment equipment disclosed in publication number CN209923146U, have the advantage of using scrapers to clean the filter screens. However, the filter screens in this screen tank are inconvenient to use and clean alternately during use, which leads to problems such as untimely cleaning and the screen tank becoming unusable during cleaning. Therefore, we propose an MBR wastewater treatment and greywater reuse device. Utility Model Content

[0026] The following describes, with reference to the accompanying drawings, some embodiments of the MBR wastewater treatment and greywater reuse device provided by this utility model.

[0027] Example 1:

[0028] Combination Figure 1-5As shown, the MBR wastewater treatment and reclaimed water reuse device provided by this utility model includes: a main body 100 and a filter assembly 200; the main body 100 includes a pretreatment tank 101, an equalization tank 102, an MBR membrane filter tank 103, a disinfection tank 104, and a control box 105 fixedly installed at the outer end of the pretreatment tank 101; the filter assembly 200 includes a filter grid 201 movably installed inside the pretreatment tank 101, a left filter chamber 202 and a right filter chamber 203 respectively arranged on both sides of the filter grid 201, a first electric push rod 204 fixedly installed on both sides of the pretreatment tank 101, a pusher block 205 fixedly installed at the front end of the first electric push rod 204, a discharge port 206 penetrating through both sides of the pretreatment tank 101, and a discharge nozzle 207 fixedly installed at the outer end of the discharge port 206; an inlet pipe 208 is also fixedly installed on one side of the pretreatment tank 101. A sealing gasket 209 is fixedly installed at one end of the filter grid 201. Fixing ears 210 are fixedly installed on both sides of the bottom of the filter grid 201. Fixing rods 211 are movably installed in the fixing ears 210, and both ends of the fixing rods 211 are fixed to the inner wall of the pretreatment tank 101. A left positioning block 212 and a right positioning block 213 are fixedly installed on both sides of the fixing rods 211 respectively. A second electric push rod 214 is fixedly installed on one side of the pretreatment tank 101, and the front end of the second electric push rod 214 is fixed to the filter grid 201. A stop block 215 is fixedly installed on one side of the pretreatment tank 101. A front scraper 216 and a rear scraper 217 are fixedly installed on both sides of the bottom of the push block 205 respectively. A brush plate 218 is fixedly installed at the center of the bottom of the push block 205. The first electric push rod 204 and the second electric push rod 214 are electrically connected to the control box 105.

[0029] Specifically, the greywater reuse device is a wastewater treatment equipment, mainly used for the purification and reuse of industrial organic wastewater and domestic sewage. The left filter chamber 202 and right filter chamber 203, located on both sides of the filter screen 201 in the pretreatment tank 101, can be alternately moved to the bottom of the inlet pipe 208 by the adjustment of the second electric push rod 214 to filter wastewater, thus avoiding clogging problems caused by prolonged use of individual filter structures. Simultaneously, during the alternating use of the left filter chamber 202 and right filter chamber 203, unused filter chambers can also have their filtered impurities promptly and uniformly pushed out by the pusher block 205 driven by the first electric push rod 204, and discharged through the discharge port 206 and discharge nozzle 207 on one side, preventing the filtered impurities from accumulating in the left filter chamber 202 or right filter chamber 203. Furthermore, the front scraper 216 and rear scraper 217 located on the front and rear sides of the bottom of the pusher block 205, as well as the brush plate 218 in the middle, ensure effective pushing of impurities into the left filter chamber 202 and right filter chamber 203. The left filter chamber 202 and the right filter chamber 203 can also be cleaned to avoid the problem of filtration effect being affected by the blockage of pores. The sealing gasket 209 fixedly installed on one side of the filter grid 201 is mainly used to ensure the sealing between one side of the left filter chamber 202 or the right filter chamber 203 and the inner wall of the pretreatment tank 101 during use. The baffle 215 fixedly installed on one side of the pretreatment tank 101 is mainly used to block one end of the left filter chamber 202 or the right filter chamber 203 during use to prevent the filtered debris from flowing out through one end of the left filter chamber 202 or the right filter chamber 203. The fixing ear 210 fixedly installed at the bottom of the filter grid 201 and the fixing rod 211 movably installed at the outer end of the fixing ear 210 are mainly used to support the bottom of the filter grid 201 to maintain its stability during use. The left positioning block 212 and the right positioning block 213 fixedly installed on both sides of the fixing rod 211 are mainly used to position the left filter chamber 202 and the right filter chamber 203 during use.

[0030] Working principle and usage process of this utility model:

[0031] After the wastewater is introduced through the inlet pipe 208, it will first be transported to the left filter chamber 202 on the left side of the bottom filter screen 201 for filtration. Impurities will be filtered out in the left filter chamber 202. After a certain amount of impurities are filtered out, the second electric push rod 214 can be activated to pull the filter screen 201 to the left, thereby pulling the filter screen 201 to the left positioning block 212, so that the right filter chamber 203 on the right side of the filter screen 201 can move. Move to the bottom of the inlet pipe 208 to filter the wastewater. After the left filter chamber 202 is moved out, it will be at the outer end of the pusher block 205. At this time, start the first electric push rod 204 to drive the pusher block 205 to push the impurities filtered in the left filter chamber 202 into the discharge port 206 and discharge nozzle 207 for discharge. During the pushing of the material by the pusher block 205, the brush plate 218 at the center of its bottom can also clean the left filter chamber 202 to clear the blocked pores and ensure the filtration effect in subsequent use.

[0032] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
