Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to energy-saving sewage treatment equipment. Background Art

[0002] In daily life, a large amount of sewage is generated. Domestic sewage needs to be treated before discharge. Domestic sewage is the wastewater discharged in the daily life of residents. It mainly comes from residential buildings and public buildings, such as residences, institutions, schools, hospitals, shops, public places and industrial enterprise toilets. The pollutants contained in domestic sewage are mainly organic matter and a large number of pathogenic microorganisms. The organic matter in domestic sewage is extremely unstable and easy to decay and produce odor. Bacteria and pathogens multiply in large numbers with organic matter in domestic sewage as nutrition, which can lead to the spread of infectious diseases. Therefore, domestic sewage must be treated before discharge, and then treated through filtration, biochemical treatment, sedimentation, disinfection and other steps.

[0003] However, domestic sewage treatment devices have certain defects in actual use. Most of them use screens to intercept large particles of impurities and suspended matter before treatment, but it is inconvenient to clean them. Over time, it is easy to cause accumulation on the screens, affecting the flow of water and thus affecting the water treatment efficiency. Utility Model Content

After preliminary filtration, the rear end is connected to a water storage tank 2, and a lifting pump (which is convenient for extracting sewage for subsequent purification operations) and a liquid level meter (which can be a float or an ultrasonic liquid level meter, which is convenient for monitoring the internal liquid level) can be arranged inside the water storage tank 2, and the water storage tank 2 is connected to a flow meter well 3 (a relatively mature technology, which will not be described here) through a lifting pump and a liquid outlet pipe 11 (which can be provided with a check valve and a ball valve), and an anaerobic tank 4 is arranged on the flow meter well 3 through a first connecting pipe 12;

[0023] The rear end of the anaerobic tank 4 is provided with an anoxic tank 5, an aerobic tank 6 and a sedimentation tank 7 of a purification mechanism in sequence, wherein a sludge return pipe may be provided between the sedimentation tank 7 and the anaerobic tank 4, a nitrification liquid return pipe may be provided between the aerobic tank 6 and the anaerobic tank 4, and an aeration device may be provided in the aerobic tank 6. The sedimentation tank 7 is provided with a disinfection well 9 (with disinfectants such as sodium hypochlorite inside) through a discharge pipe 14, and a dosing barrel 8 is provided under the sedimentation tank 7. The two are connected by a dosing inlet pipe 13 (which may be a flocculant, etc., and is provided according to actual conditions). Both are common devices in sewage treatment devices and are not described in detail here. The disinfection well 9 is then connected to the outlet well 10 through a second connecting pipe 15, and a discharge pipe 16 is provided on the side wall of the outlet well 10, which can facilitate the discharge of the treated water that meets the standards.

[0024] See also Figure 1-Figure 5 In order to regularly clean the grille 21 and take out the large particles of impurities and suspended matter in the pretreatment box 1 for cleaning, an empty slot is provided at the top of the pretreatment box 1, and a sealing plate 20 of a lifting assembly is provided in the empty slot (a sealing gasket may be bonded to the surrounding side to ensure the sealing effect with the empty slot), and two groups of electric push rods 18 are installed on the side wall of the pretreatment box 1, and a connecting piece 19 with an L-shaped cross-section is installed at the output end of the electric push rod 18. The connecting piece 19 is welded and fixed to the sealing plate 20, and four groups of connecting columns 23 (located inside the pretreatment box 1) are vertically welded to the bottom of the sealing plate 20. The bottom ends of the four connecting columns 23 are welded together with a collecting bucket 22, which can facilitate the collection of large particles of impurities intercepted and filtered by the grille 21, and facilitate subsequent pulling out and cleaning, and a leakage hole 24 is provided at the bottom of the collecting bucket 22 for convenient water discharge.

[0025] Working principle: When the utility model is in use, the sewage is introduced into the pretreatment box 1 through the sewage inlet pipe 17, the large particles of impurities and suspended solids are filtered through the grille 21, and then introduced into the water storage tank 2, and then pumped into the flow meter well 3 through the liquid outlet pipe 11, and then introduced into the anaerobic tank 4, the anoxic tank 5, the aerobic tank 6 and the sedimentation tank 7 in sequence through the first connecting pipe 12, so as to treat and purify the sewage, and then the liquid (which can be a flocculant) in the dosing barrel 8 is added to the sedimentation tank 7 through the dosing inlet pipe 13 for further treatment, and the precipitated liquid enters the disinfection well 9 through the second connecting pipe 15 for treatment. After disinfection, the wastewater is passed through the second connecting pipe 15 to the water outlet well 10, and is discharged through the discharge pipe 16 after meeting the standards. After a period of use, when it is necessary to clean the large particles of impurities and suspended matter in the pretreatment box 1, the electric push rod 18 is extended to move the sealing plate 20 under the connecting piece 19 upward, and then move the collecting bucket 22 under the connecting column 23 upward to bring out the impurities, and the water flows out through the leakage hole 24, and then the collecting bucket 22 is removed and cleaned. After cleaning, the electric push rod 18 shrinks and moves the whole thing downward to reset, which does not affect the subsequent sewage treatment.
