Description

Domestic wastewater regeneration treatment system

Technical Field

This scheme relates to the treatment facility technical field of sewage, specifically is living waste water regeneration system.

Background

Along with the improvement of living standard of people, more and more impurities are contained in the domestic wastewater. Therefore, for environmental protection, domestic wastewater needs to be treated before being discharged into the natural environment, so as to reduce the influence of the domestic wastewater on the environment. The treatment of domestic wastewater is generally completed in a wastewater treatment system, the wastewater treatment system comprises a filter tank, a sedimentation tank, a biochemical treatment tank and a disinfection treatment tank, the domestic wastewater is treated by the filter tank to remove solid matters with larger volume, then the small solid matters are precipitated in the sedimentation tank, and then the domestic wastewater is discharged into the biochemical treatment tank to treat substances dissolved in water, and finally the domestic wastewater is disinfected in the disinfection tank to meet the discharge requirement. Domestic wastewater contains kitchen wastewater, which contains a large amount of oil. When the waste water that contains oil is handled in the sedimentation tank, oil can float on the surface of water, because oil has certain stickness, then oil can adhere on the pool wall of sedimentation tank, then oil contact with the bacterium in the air for a long time, and oil can give off some smell of nauseing to the colour changes, makes the pool wall of sedimentation tank very dirty, influences the processing of waste water.

Disclosure of Invention

The invention aims to provide a domestic wastewater regeneration treatment system to solve the problem that a large amount of oil is easy to adhere to the wall of a sedimentation tank in the prior art.

The basic scheme of the invention is as follows: domestic wastewater regeneration processing system, including the sedimentation tank, be equipped with a plurality of jet-propelled mechanisms on the pool wall of sedimentation tank, jet-propelled mechanism includes jet-propelled mouth shower nozzle down, the inside of pool wall is equipped with the gas storage chamber, shower nozzle and gas storage chamber intercommunication, the inside of pool wall still is equipped with air pressure boost chamber, air pressure boost chamber passes through the air duct intercommunication with the gas storage chamber, install electric valve on the air duct, the below of shower nozzle is equipped with the riser of being made by oleophylic hydrophobic material, fixedly connected with slider on the riser, vertical and pool wall sliding connection are followed to the slider, be equipped with the elastic component that makes the slider reset on the pool wall, limit switch has set firmly in the below of slider, limit switch and electric valve electric connection.

The working principle is as follows: when the water level in the settling tank rapidly drops, the oil layer floating on the water surface also drops. Because the water is positioned at the lower side of the oil layer, the water firstly enters the vertical pipe, and because the vertical pipe has hydrophobicity, the water and the vertical pipe cannot generate larger adhesive force, so that the water cannot drive the vertical pipe to move downwards in the descending process. Then, when the water in the riser is lowered to make the oil enter the riser, the oil will move slowly due to the oil viscosity and the greater adhesion between the riser and the oil due to the oleophilicity of the riser. When the water of riser lower part descends, make the interface production negative pressure of oil and water in the riser, make the gravity of water pass through atmospheric pressure and transmit the oil, oil is transmitting power for the riser, thereby make the riser fall because of the weight increase, and then make limit switch closed, make electric valve open, thereby make the high-pressure air in the air pressurizing chamber enter into the gas storage chamber through the air duct and spout from the shower nozzle, shower nozzle spun high-pressure draught blows off the oil on the pool wall downwards, reduced the oil of adhesion on the pool wall, be favorable to the clean and tidy of pool wall.

Compared with the prior art, the scheme has the advantages that: 1. through the vertical pipe, the oil is high in viscosity and high in bonding force with the vertical pipe, and meanwhile, the bonding force between water and the vertical pipe is low, so that the water transmits force to the oil and the vertical pipe under the action of atmospheric pressure, the gravity of the vertical pipe is increased by the gravity of the water and the oil, the vertical pipe descends and triggers the limit switch, the spray head sprays air, the oil adhered to the wall of the pool is less, and the cleanness of the wall of the pool is kept. 2. The vertical pipe is not driven to move downwards when water descends by utilizing the hydrophobicity of the vertical pipe, and the spray head can spray air only when oil enters the vertical pipe and then moves downwards, so that the air spraying of the spray head is sequentially opened from top to bottom along with the descending of the water level, and the oil on the pool wall is blown off from top to bottom in sequence, and the phenomenon of secondary pollution is avoided. 3. The air sprayed by the spray head can eat the oil and water in the vertical pipe, so that the vertical pipe moves upwards due to the reduction of weight, the limit switch is switched off, the spray head stops spraying air, the automatic closing is realized, and the manual operation is not needed.

Further, the elastic part is a spiral tension spring. The spiral tension spring is simple to manufacture and convenient to maintain.

Furthermore, the limit switch is a swing rod type limit switch. The swing rod type limit switch is simple in structure and beneficial to reducing cost.

Further, the lower part of the inner side of the vertical pipe is provided with two separated conducting strips, the outer side of the sedimentation tank is provided with a supercharger communicated with the air supercharging cavity, one of the two conducting strips is electrically connected with a limit switch, the other conducting strip is electrically connected with a control switch of the supercharger, and the limit switch is electrically connected with the control switch of the supercharging motor. Through setting up two conducting strips, when two conducting strips and the water contact in the riser, two conducting strips can be switched on. Then when the limit switch is closed, the control circuit of the supercharger is conducted, the supercharger works and supercharges the air supercharging cavity, and pressure loss caused by air injection of the nozzle is compensated.

Further, the spiral tension spring is sleeved with an air bag. The spiral tension spring is surrounded by the air bag, so that the spiral tension spring cannot be contacted with wastewater, and the spiral tension spring is prevented from being corroded by the wastewater.

Furthermore, the free end of the swing rod type limit switch is rotatably connected with a roller. Through setting up the gyro wheel, can reduce the frictional force between pendulum rod and the slider, reduce wearing and tearing.
