1. The work that needs to be done before starting the shallow air flotation: check the switching power supply route and run it at full load for a short time to distinguish whether the pump and air compressor are running normally, whether there is noise and heat, and whether the agitator is normal when the water cooler is introduced turn. Move the sludge collection pressure reducer to see if it rotates normally. If there is impact and instability, clean it up immediately, turn on the main power switch of the dissolving machine, prepare according to the regulations of the concentration value of the liquid medicine, stir until the concentration value of the liquid medicine is symmetrical, and put the gas The float is cleaned without leaving any dirt. Check if the connection is loose and if there is grease in the swivel.
2. Difficulties that should be paid attention to in the application of shallow air flotation: it is necessary to ensure that the water level of the air flotation machine neither engulfs the packing layer nor is lower than 0.6m, so as to prevent it from containing a large amount of undissolved gas and endanger the actual effect of the fluctuation . If the temperature in the air flotation machine is low, the method of increasing the dosage can be used to fill the upward adjustment characteristics of the flocs under pressure due to the increase in the viscosity of the flowing water, so as to ensure the effluent water body; the shallow air flotation is settled according to the inclined plate of the reflecting pool. The conversion of sludge and effluent water in the separation zone of the tank and the air flotation tank should be adjusted immediately. When the air flotation machine is used, it must have the ability to eliminate pollution, so as to know how much total area can be solved when it is used.
