Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to an improved wastewater treatment equipment. Background Technology

[0002] Over time, the concentration of pollutants in wastewater treatment equipment filtration systems increases. Therefore, when the pollutants trapped in the filter reach a certain level, backwashing is necessary. Directly discharging backwash water into the environment will cause secondary pollution and waste water resources. If the backwash water is recycled at the front end of the screen, the nutrients such as nitrogen, phosphorus, and COD required by bacteria in the various biological treatment systems have already been removed. The addition of this water dilutes the nutrient concentration in the water. Moreover, since the treatment capacity of domestic wastewater treatment systems is fixed, the addition of this water actually circulates continuously within the system, reducing the amount of domestic wastewater treated and recycled, thus reducing the efficiency of the entire system and hindering the achievement of environmental protection targets and the rational use of water resources.

[0003] Therefore, the purpose of this utility model is to provide an improved sewage treatment equipment, which aims to solve the problems in the prior art. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution: an improved sewage treatment device, including a sewage collection tank 1 and a sewage treatment mechanism 3. A primary filter 2 is arranged on the left side of the sewage collection tank 1, and the sewage treatment mechanism 3 is arranged on the left side of the primary filter 2. A backwash tank 301 is arranged on the left side of the primary filter 2, a secondary filter 302 is arranged on the left side of the backwash tank 301, a biological treatment tank 303 is arranged on the left side of the secondary filter 302, a tertiary filter 304 is arranged on the left side of the biological treatment tank 303, and a disinfection treatment tank 305 is arranged on the left side of the tertiary filter 304. A medicine storage tank 306 is installed at the top, a dosing pump 307 is installed at the front end of the medicine storage tank 306, a support frame 308 is installed on the left side of the dosing pump 307, a disinfection spray pipe 309 is installed at the bottom of the support frame 308, a nozzle 310 is installed at the bottom of the disinfection spray pipe 309, a fine-hole inclined plate collection tank 311 is installed on the left side of the disinfection treatment tank 305, a drain pipe 312 is installed on the left side of the fine-hole inclined plate collection tank 311, a return washing pipe 313 is installed at the front of the disinfection treatment tank 305, a valve 314 is installed on one side of the return washing pipe 313, and a pump 315 is installed at the end of the return washing pipe 313.

[0021] Furthermore, the sewage collection tank 1 and the primary filter 2 are connected by a slot, and the primary filter 2 fits tightly with the sewage collection tank 1. With this setting, the primary filter 2 is located on the upper left side of the sewage collection tank 1, which can effectively settle and filter large impurities and particles for preliminary filtration.

[0022] Furthermore, wastewater can flow between the backwash tank 301 and the biological treatment tank 303. A secondary filter 302 is connected between the backwash tank 301 and the biological treatment tank 303 via a slot. This design allows the secondary filter 302 to be easily maintained and replaced. The secondary filter 302 can effectively intercept larger particles in the wastewater, improving the effect of subsequent biological treatment.

[0023] Furthermore, sewage can flow between the biochemical treatment tank 303 and the disinfection treatment tank 305. A three-stage filter screen 304 is connected between the biochemical treatment tank 303 and the disinfection treatment tank 305 via a slot. This arrangement allows sewage to flow smoothly between the biochemical treatment tank 303 and the disinfection treatment tank 305. The three-stage filter screen 304 further filters out fine particulate matter in the sewage, thus performing further filtration.

[0024] Furthermore, the nozzle 310 is connected to the disinfection spray pipe 309 by screws, and the nozzle 310 is evenly and symmetrically distributed at the bottom of the disinfection spray pipe 309. With this setting, uniform spraying can ensure that the disinfectant fully covers the sewage and enhance the disinfection effect.

[0025] Furthermore, the fine-pore inclined plate collection tank 311 is connected to the disinfection treatment tank 305 by a pipe, and the fine-pore inclined plate collection tank 311 is connected to the drain pipe 312 by a slot seal. With this setting, the backwashed water is collected in the fine-pore inclined plate collection tank 311 and discharged together with the sewage treated at the front end in compliance with standards. The fine-pore inclined plates in the fine-pore inclined plate collection tank 311 can be disassembled at any time to clean the suspended solids and other pollutants adhering to them, which is simple and convenient.

[0026] Furthermore, the backwash pipe 313 and valve 314 are connected by a flange. Both the biochemical treatment tank 303 and the disinfection treatment tank 305 are equipped with backwash pipes 313 and valves 314. The backwash pipe 313 at the outlet of pump 315 is connected to the backwash tank 301. With this arrangement, the flange connection allows the backwash pipe 313 and valve 314 to be easily disassembled and maintained, while also facilitating the adjustment and control of the backwash process. The backwash pipe 313 ensures the regular backwashing of the biochemical treatment tank 303 and the disinfection treatment tank 305, which helps to maintain the efficient operation of the system.

[0027] Working principle: First, wastewater enters the primary filter 2 through the wastewater collection tank 1. The primary filter 2 is located in the upper left part of the wastewater collection tank 1 and is responsible for preliminary filtration, removing larger particulate impurities and suspended solids. Then, the filtered wastewater flows into the wash tank 301, where the secondary filter 302 further intercepts larger particles to improve the effect of subsequent biological treatment. Wastewater passing through the secondary filter 302 flows into the biological treatment tank 303, where it undergoes biological treatment to remove organic pollutants. After biological treatment, the wastewater passes through the tertiary filter 304, which is located between the biological treatment tank 303 and the disinfection treatment tank 305, to further filter out finer particles. Then, the wastewater passing through the tertiary filter 304 enters the disinfection treatment tank 305, where it is mixed with disinfectant. The disinfectant is stored in the storage tank 3. The disinfectant in 06 is delivered to the disinfection spray pipe 309 by the dosing pump 307. The nozzle 310 sprays the disinfectant evenly onto the sewage to ensure the disinfection effect. The disinfected sewage flows from the disinfection treatment tank 305 into the fine-hole inclined plate collection tank 311. The fine-hole inclined plate collection tank 311 is connected to the drain pipe 312 through a pipe. The backwash water also collects in the fine-hole inclined plate collection tank 311 and is discharged together with the treated sewage. Finally, the backwashing process is controlled by the valve 314 set in the backwash pipe 313, and the water flow is sent back to the backwash tank 301. The water flow is increased by the pump 315 to ensure the cleanliness and efficient operation of the backwash pipe 313, the backwash tank 301, the biological treatment tank 303, and the disinfection treatment tank 305. This completes the use process of an improved sewage treatment equipment.
