Dissolved air flotation machine is a kind of equipment to remove jelly in wastewater, and it is now an important equipment to protect the environment. Work efficiency is the direct factor that determines the quality of equipment, so how should the work efficiency of the air floatation machine be improved? Let's take a closer look at the work that needs to be done before starting the dissolved air flotation machine and the issues that need to be paid attention to during use.
1. What needs to be done before starting the dissolved air flotation machine: check the power line and perform a short no-load operation to determine whether the pump and air compressor are turning correctly, whether there is noise or heat, and the mixer is activated after injecting clean water to judge it. Whether the steering is correct. Jog the scum collection reducer to observe whether its steering is correct, whether there are collisions and unevenness, and eliminate them in time, turn on the power switch of the dissolver, configure according to the concentration of the drug solution, and stir until the concentration of the drug solution is uniform. Clean the dissolved air flotation machine without leaving any foreign matter. Check whether the connection part is loose and the lubricating oil in the rotating part is injected.
2. Problems to be paid attention to in the use of the dissolved air flotation machine: It is necessary to ensure that the water level of the dissolved air flotation machine does not submerge the filler layer and is not less than 0.6m. This is to avoid a large amount of undissolved air in the air and affect the undulating effect. If the water temperature in the dissolved air flotation machine is low, the method of increasing the dosage can be adopted to compensate for the decrease in the floating performance of the air-carrying flocs due to the increase in water flow viscosity, and to ensure the water quality of the effluent; the dissolved air flotation machine is based on the flocculation and separation of the dissolved air flotation pool Change the scum and effluent quality in the area, adjust the dosage of coagulant in time; operate the scum scraper regularly to remove the scum, establish a slag scraping system that meets the actual situation, and the dissolved air flotation machine must be released when in use The ability to pollute in this way can know how much area can be handled when it is used.
The above are two ways to improve the working efficiency of the dissolved air flotation machine, I hope it can be helpful to everyone.
