Slaughterhouse wastewater treatment equipment

Slaughterhouse wastewater treatment equipmentThe air dissolved in water is released from the water, forming particles with a diameter of20-50μmMicrobubbles combine with suspended solids in wastewater, reducing their specific gravity until they float to the surface of the water; A large amount of floating slag is formed, which is then removed by a chain scraper installed on the air flotation tank to achieve the desired treatment effect.

2、 Main Structure Description

1Air flotation system

The air flotation system integrates water intake, flocculation, separation, water collection, and effluent. Similar to traditional air flotation equipment, it is equipped with a stable flow chamber and a dissolved air release chamber, making the treatment performance more stable and the effect more efficient. Stable chamber: The raw water reacted through folded plates has a high flow rate. If it comes into direct contact with dissolved air water, it will dissipate small bubbles, affecting the adhesion of bubbles to flocs and reducing the efficiency of air flotation treatment. If a stable flow chamber is added, the kinetic energy of turbulent raw water will be consumed and enter the dissolved air water release chamber at a uniform speed, effectively ensuring the removal effect.

Dissolved gas release chamber: The dissolved gas release chamber and the separation chamber are located in the same tank. Separated in the middle, the dissolved air water and the flocculated raw water adhere here, slowly rise, and enter the air flotation separation chamber, ensuring the contact space and time between the flocs and small bubbles, and achieving the release rate of dissolved air water80-99

2Dissolved gas system

For air flotation equipment, the dissolved air system is like an air flotation equipment“heart”It is also a major component of air flotation equipment. At this stage, air and water are sucked in together at the inlet of the pump, and mixed into dissolved air and water through shear and pressure. The gas-liquid phase is fully mixed and reaches saturation,The entire dissolved gas system has a high gas content of10%And the solubility of the gas is100When the gas is dispersed, the distribution of microbubbles is uniform, and the average bubble diameter is less than30umThe dissolved air system is an improvement and technological innovation of traditional air flotation, which enhances the separation efficiency of air flotation and greatly reduces the production and operating costs of equipment.

3Scraper machine

The operation mode and speed of the scraper directly affect the water quality of the air flotation effluent and the solid content of the sludge. The system adopts a rotary scraper, which can continuously and uniformly scrape the floating slag into the floating slag tank, reducing the phenomenon of collision between floating slag; In addition, the height adjustable scraper can better adapt to various operating conditions and reduce the moisture content of sludge.

4Control system

The control system adopts*Electrical components are used to ensure the safety of the equipment*Effective operation.

5Supporting equipment

Air flotation agents and dosing equipment are also important factors in ensuring treatment effectiveness. We can provide matching dosing equipment and optimized combination agents according to the needs of users.

The parallel flow dissolved air flotation machine needs to be debugged after installation and before formal operation. The debugging operation of the parallel flow dissolved air flotation machine includes two methods: clean water debugging and sewage testing. Today, we will mainly talk about the sewage test method of the horizontal flow dissolved air flotation machine.
　　1Connect the sewage to be treated to the original water tank(The water level cannot exceed the upper limit of the water level).
　　2Open the valve at the dosing port and turn on the dosing pump.
　　3Turn on the raw water pump, adjust the front and rear valves of the pump, and at the same time open and adjust the valve of the clean water outlet pipe leading to the raw water tank to stabilize the water in the tank at the designed height.
　　4Adjust the water level of the overflow weir of the host and remove the floating debris in place.
　　5After all the raw water entering the pool is sewage, test the effluent effect of the main unitjiaIn the effluent state, samples are taken from the sampling point of the raw water inlet pipe to test the inlet water quality, outlet water quality, dosage and other data, which are written into the commissioning report. The dosage concentration is changed to reduce the dosage and ensure that it meets the effluent water quality requirements. The interval between each test is not less than30minute.
　　6Open the valve connecting the clean water outlet pipe to the clean water tank, and close the valve connecting the clean water outlet pipe to the original water tank.
　　7Observe the dissolution process of the drug dissolving machine, stir and store the drug solution at any time.
