Analysis of routine maintenance and inspection of dissolved air flotation machine:

检查工作,希望对大家是有帮助的。 The daily maintenance and inspection of the dissolved air flotation machine is very important. Many users often ignore it. This not only greatly reduces the service life of the dissolved air floatation machine, but also affects the normal operation of the equipment. The following introduces the dissolved gas to you. The daily maintenance and inspection of the floating machine is hopeful to everyone.
Analysis of routine maintenance and inspection of dissolved air flotation machine
1. Regularly check the filling and lubrication systems of air compressors and water pumps, and often refuel.
泡与絮粒黏附不好,应检查并对混凝系统进行调整或采取适当措施(如投加表面活性剂等);不合格出水返回集水池,合格出水进入后续处理系统。 2. Frequently investigate the surface condition of the air flotation tank of the dissolved air flotation machine. If the scum surface in the contact area is found to be uneven, and large bubbles or water flow is unstable, the releaser should be removed to eliminate the blockage. Large bubbles often rupture on the surface, indicating that the bubbles and flocs do not adhere well. Check and adjust the coagulation system or take appropriate measures (such as adding surfactants); unqualified effluent returns to the catchment tank, and is qualified. The effluent enters the subsequent processing system.
3. Make daily operation records of the dissolved air flotation machine, including the amount of treated water, dosage, dissolved water, dissolved gas tank pressure, water temperature, power consumption, inlet and outlet water quality, slag discharge cycle, and sludge moisture content.
气絮粒的上浮性能,从而保证出水水质正常。 4. In the period when the water temperature is too low in winter, because of the poor flocculation effect, in addition to usually increasing the dosage, sometimes the dissolved air floater needs to increase the amount of dissolved water or the pressure of the dissolved gas to allow more micro-bubbles to adhere to the flocculent particles. Make up for the impact of air floc on the floating performance due to the increase of the viscosity of the water flow , so as to ensure the normal quality of the effluent water.
5. According to the flocculation of the reaction tank, scum in the air flotation zone and the quality of the effluent water, pay attention to adjusting the parameters such as the amount of coagulant added, and especially to prevent the blocking of the dosing tube.
6. Frequently check the water level indicating tube of the dissolved gas tank to control it within a certain range (generally within 60-100 cm). To ensure the effect of dissolved gas. Avoid the destruction of water purification effect and scum layer due to the emptying of the water level of the dissolved gas tank, causing a large amount of air to enter the air floating pond. 有溶气罐液位自动控制装置的,则需注意设备的维护保养。 For the automatic level control device of the dissolved gas tank, the maintenance of the equipment should be paid attention to.
The above is all the content introduced for everyone, I hope to help everyone. If you want to learn more, you can browse our website and we will provide you with more professional information.
