Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to organic wastewater treatment equipment. Background Art

[0002] At present, a large number of manufacturers that process accessories need to use organic cleaning solvents to clean the accessories, which will produce a certain amount of organic wastewater. The composition of the wastewater after cleaning the accessories is relatively simple, and the amount of wastewater generated is small. The main component of the wastewater is organic alcohol, and its characteristic pollution indicators are mainly high COD (about 8000-15000 mg / L), lack of nutrients such as nitrogen and phosphorus, and need to undergo anaerobic and aerobic treatment.

[0003] In the existing anaerobic treatment of organic wastewater, the bottom sludge absorbs gas and floats up, and the floating sludge generated cannot be well treated and recovered, and enters the aerobic system along with the water flow, affecting the quality of wastewater treatment. Therefore, an organic wastewater treatment equipment is proposed to provide an organic wastewater anaerobic treatment mechanism with good water distribution and water discharge uniformity and floating sludge efficient collection components for the wastewater generated by the machine cleaning solvent for cleaning accessories, so as to avoid the sludge accompanied by anaerobic bacteria from destroying the bacteria in the aerobic tank, thereby ensuring the quality of organic wastewater treatment.

[0017] Specifically, the triangular overflow weirs are arranged at equal distances along the overflow outlet.

[0018] By adopting the above technical solution, the wastewater after anaerobically treatment in the tank body can be evenly overflowed through the triangular overflow weir.

[0026] The auger runs through the bottom of the lower partition.

[0027] By adopting the above technical solution, the floating sludge in the anaerobic tank is precipitated and filtered through the floating sludge treatment part, and spirally discharged for unified recycling by workers.

[0028] Specifically, the shaft heads at both ends of the auger are rotatably connected to the water outlet pool and the mud discharge channel through sealed bearings respectively. A motor is installed outside the mud discharge channel, and the driving end of the motor is connected to the shaft head at one end of the auger through a coupling.

[0029] Specifically, the aerobic pool connecting pipe is located below the slope plate.

[0030] The beneficial effects of the utility model are as follows: through the components consisting of the anaerobic tank, the pulse water distributor, the triangular overflow weir and the floating sludge treatment part, the wastewater generated by the cleaning accessories of the machine cleaning solvent is realized, and a set of organic wastewater anaerobic treatment mechanism with good water distribution and water discharge uniformity and a floating sludge efficient collection component is provided, so as to avoid the sludge accompanied by anaerobic bacteria from destroying the bacteria in the aerobic tank, thereby ensuring the quality of organic wastewater treatment, and utilizing the siphon principle of the pulse water distributor, without power, to evenly distribute raw water and nutrients into the anaerobic tank, so that the organic wastewater can be better anaerobic treated, and the problem that in the existing anaerobic treatment of organic wastewater, the floating sludge generated cannot be well treated and recovered due to the bottom sludge adsorbing gas and floating up, and enters the aerobic system along with the water flow, thereby affecting the quality of wastewater treatment.

DETAILED DESCRIPTION

The siphon principle of the pulse water distributor 2 is utilized to evenly distribute the raw water and the nutrient agent into the anaerobic tank without power, so that the organic wastewater can be better anaerobic treated.

[0045] For example, Figure 2 , 3 As shown, the utility model also includes that the anaerobic tank 1 includes:

[0046] Pool body 101;

[0047] The overflow port 102 is arranged at one end of the top of the tank body 101;

[0048] A water inlet interface 103 connected to the tank body 101;

[0049] At least one group of annular filter materials 104 is provided and arranged along the pool body 101 .

[0050] In order to ensure the uniformity of water discharge, for example, Figure 1 As shown, the utility model also includes that the triangular overflow weir 3 is arranged at equal distances along the overflow port 102 .

[0051] The overflow surface of the triangular overflow weir is at a 45-degree angle. This design can improve the water level regulation ability of the water body, while reducing resistance and improving the uniformity of water discharge.

[0052] To filter the floating sludge, for example, Figure 1 , 2 As shown in 4, the utility model also includes that the floating sludge processing unit 4 includes:

[0053] The water outlet pool 401 is connected to the pool body 101;

[0054] The aerobic pool connecting pipe 402 is connected to the water outlet pool 401;

[0055] The ramp 403 is arranged at the top of the water outlet pool 401;

[0056] At least one set of upper partition plates 404 is provided and connected along the bottom of the ramp plate 403;

[0057] The lower baffle 405 is staggered with the upper baffle 404 and fixed to the bottom of the water outlet pool 401;

[0058] The mud discharge channel 406 is connected to the water outlet pool 401;

[0059] The auger 407 passes through the bottom of the lower partition 405 .

[0060] When in use, the floating sludge in the water source is precipitated and filtered through the flow column formed by the upper partition 404 and the lower partition 405 to improve the cleanliness of the water source discharged from the anaerobic tank 1, prevent the floating sludge from entering the aerobic tank of the next process, and reduce the processing complexity of the next cutting process.

[0061] The shaft heads at both ends of the auger 407 are rotatably connected to the water outlet pool 401 and the mud discharge channel 406 through sealed bearings respectively. A motor 408 is installed on the outer side of the mud discharge channel 406. The driving end of the motor 408 is connected to the shaft head at one end of the auger 407 through a coupling.

[0062] When in use, the auger 407 is driven by the motor 408, and the auger 407 transports the sludge at the bottom of the outlet pool 401 to the sludge discharge channel 406, which is then collected by the water treatment personnel.

[0063] The aerobic pool connecting pipe 402 is located below the slope plate 403 .

[0064] When the utility model is in use, the organic wastewater to be treated is discharged to the tank body 101 with the annular filter material 104 through the water inlet interface 103, and the raw water and the nutrient agent are evenly distributed to the anaerobic tank without power through the siphon principle of the pulse water distributor 2, so that the organic wastewater is well anaerobic treated. The aerobic tank connecting pipe 402 is connected to the water inlet end of the aerobic tank, so that the wastewater enters the aerobic system after being decomposed by the anaerobic bacteria. During this period, the floating sludge treatment part 4 performs a simple filtering treatment on the water source before entering the aerobic tank, reducing the invasion of the floating sludge into the aerobic tank, and avoiding the sludge accompanied by the anaerobic bacteria to destroy the bacteria in the aerobic tank, so as to ensure the quality of the organic wastewater treatment. The floating sludge accompanying the water source is precipitated and filtered through the flow column formed by the upper partition 404 and the lower partition 405, so as to improve the cleanliness of the water source discharged from the anaerobic tank 1, avoid the floating sludge from entering the aerobic tank of the next process, and reduce the processing complexity of the next cutting process.
