Background
The air floatation machine is a device for removing solid suspended substances, grease and various jellies in various industrial and municipal sewage. The device is widely applied to the treatment of industrial wastewater and municipal sewage in oil refining, chemical industry, brewing, vegetable oil production and refining, slaughtering, electroplating, printing and dyeing and the like. The air flotation method is a flotation method commonly used in sewage treatment, and is a flotation method by utilizing micro-bubbles formed by air compression and instant release or mechanical shearing. Common methods for forming bubbles can be divided into suction air flotation machines with water suction pipes of water pumps, diffusion plate aeration air flotation, jet air flotation and impeller air flotation machines. An operation for separating and removing hydrophobic contaminant ions contained in a multiphase system of sewage, contaminant substances and air bubbles from water in the form of foam by selectively adsorbing the hydrophobic contaminant ions onto the air bubbles from the sewage. The air floatation method is a water treatment technique in which a large amount of micro-bubbles are injected into water or generated by an electrolysis method, so that the micro-bubbles are adhered to solid or liquid pollutant particles with density close to that of water in waste water to form an air floating body with density lower than that of water, and the air floating body floats to the water surface under the action of buoyancy to form floating slag for solid-liquid or liquid-liquid separation. The air flotation method is mainly used for removing suspended matters, oils and fats with relative density from the wastewater, and can also be used for concentrating high-concentration wastewater and then pressing and drying the wastewater by a belt filter press. The pollutant particles in the wastewater can be stably adsorbed on the bubbles and float upwards along with the bubbles, which is a precondition for air floatation separation, and therefore, the removed pollutant particles have hydrophobic surfaces. In order to improve the separation effect of the air flotation method, the sludge dewatering machine usually adopts measures to change the surface characteristics of solid or liquid pollutant particles, adds a certain amount of suspending agent into water to convert hydrophilic particles into hydrophobic particles, and adds a demulsifier (coagulant) into emulsified oil wastewater to aggregate emulsified oil which is difficult to float into suspended matters to remove. The air flotation machine is divided into two types according to an air dissolving mode, namely a cavitation air flotation machine and an air dissolving air flotation machine, wherein the cavitation air flotation machine efficiently pressurizes and mixes gas or more than two different liquids which are difficult to dissolve in water by utilizing the special stirring function of vortex, and the particle size of generated micro bubbles is 20-50 micrometers. The stirring technology greatly simplifies the traditional stirring process, not only can realize the miniaturization of equipment, but also saves the investment and the running cost. The pressurizing dissolved air flotation machine is a pressurizing dissolved air flotation system adopting a gas-liquid mixing pump, omits complex arrangements of a pressurizing pump, an air compressor, a jet device, a high-pressure dissolved air tank and the like, and only needs simple debugging once.
Ozone has strong oxidizability, so that organic pollutants in water can be degraded, under the condition of existence of a free radical activator or promoter, the ozone can generate a large amount of free radicals in liquid or gas, the free radicals can oxidize organic matters in the liquid or gas into simple organic matters or completely remove carbon dioxide and water in a very short time, and the ozone oxidation technology is an advanced oxidation technology.
