Installation plan for buried grease separatorIf uneven floating surface, large bubbles or unstable water flow are found in the contact area, the release device should be removed to eliminate blockage; If the surface of the floating slag in the separation zone is uneven, the coagulation system should be inspected and adjusted or appropriate measures should be taken.

1. Regularly observe the surface condition of the air flotation tank, such as adding surfactants; Unqualified effluent is returned to the collection tank, while qualified effluent enters the subsequent treatment system.
During the period of low water temperature in winter, due to poor flocculation effect, in addition to usually increasing the dosage, it is sometimes necessary to increase the amount or pressure of dissolved air to allow more microbubbles to adhere to the flocs, in order to compensate for the impact of increased water flow viscosity on the buoyancy performance of aerated flocs and ensure normal effluent quality.
3. Regularly check the water level indicator pipe of the dissolved gas tank to control it within a certain range (usually within 60-100 centimeters). To ensure the effectiveness of gas dissolution. To avoid a large amount of air entering the air flotation tank and damaging the water purification effect and floating slag layer due to the emptying of the dissolved gas tank water level. For those equipped with automatic liquid level control devices for dissolved gas tanks, attention should be paid to the maintenance and upkeep of the equipment.
4. The team work for pipeline prefabrication needs to be carried out on a steel platform for pipeline processing, while stainless steel pipelines should be carried out on a wooden platform.
5. The prefabrication of pipelines should consider in advance whether transportation and installation are convenient, leaving adjustable openings. After prefabrication is completed, the interior of the pipeline should be cleaned and the gate should be closed.
After the pipe rack is made, it should be promptly treated with rust prevention and marked.

1. According to the flocculation, floating slag and effluent quality of the reaction tank, pay attention to adjusting the dosage of coagulant and other parameters, especially to prevent blockage of the dosing tube.
2. Disinfection treatment: Our company uses chlorine dioxide disinfection equipment. The disinfection pool and disinfection device can continuously change the dosage according to the water output, achieving the goal of adding more water and more medicine, and adding less water and less medicine. Other devices can be separately prepared if needed.
3. Keep daily operation records, including water treatment volume, dosage, dissolved gas volume, dissolved gas tank pressure, water temperature, power consumption, inlet and outlet water quality, slag discharge cycle, sludge moisture content, etc.
4. Steel pipe cutting requires a smooth surface, free from various defects such as cracks, burrs, and bumps. The cut steel pipe should be promptly marked with the material specifications and the position used on each pipe section.
5. Aerobic digestion tank for sludge: The remaining sludge discharged from the sedimentation tank is subjected to aerobic digestion and stabilization treatment in the tank to reduce the volume of sludge and improve its stability. The amount of sludge after aerobic digestion is relatively small. When cleaning, a suction truck can be used to extend from the inspection hole of the sludge tank to the bottom of the tank for suction and then transported outside
6. Regularly check the packing and lubrication system of the air compressor and water pump, and regularly add oil.
7. Prefabricate pipes according to user requirements and the environmental characteristics of the construction site. Before use, check the pipe specifications, quantity, markings, and quality according to the design requirements.
