Product Description
Structure principle
Dissolved air flotation sewage processor for steel structure, its working principle is: dissolved gas into air through the pump pressure, under the pressure of 0.5 Mpa were forced to dissolve in the water, in the case of sudden release of the air dissolved in water precipitation, form to close the micro air bubble group in the process of slowly rising adsorption in the suspended solids density decreased buoyancy, remove content.
The structure is mainly composed of the following parts:
1. Air floating machine
The round steel structure is the main body and core of the water treatment plant.There are internal releaser, distributor, sludge pipe, outlet pipe, sludge tank, scraper and transmission system.Release in the centre of the flotation machine, is the key components of micro bubble, dissolving tank to dissolved air water mixed with waste water fully here, all of a sudden release of vigorous agitation and eddy current, and so attached on flocculation of waste water body, so as to reduce the rising proportion of flocculation body, clear water completely isolated, uniform process of conical structure and connection on the release, main effect is to separate the even distribution of water and sludge in the tanks, pipes that are actually bottom of tank, and through a vertical tube is connected to the tank on the point of overflow, overflow outlet without water level regulating handle, facilitate adjustment tank water level, the sludge pipe installed on the bottom of the tank,It is used for discharging sediment. There is no sludge tank on the upper part of the tank. There is a scraper on the tank.
2. Dissolved gas system
The dissolved gas system is mainly composed of dissolved gas tank, storage tank, air compressor and high-pressure pump. The dissolved gas tank is the most critical part of the system, whose function is to realize full contact between water and air and accelerate air dissolution.It is a sealed pressure steel tank, the internal design has baffles, spacers, can accelerate the gas and water dispersion, mass transfer process, improve the efficiency of dissolved gas.
3. Potions cans
Steel round tank, used for dissolving and storing medicinal liquid, two of which are dissolving tanks with stirring device, and the other two are pharmaceutical storage tanks, the volume of which is matched with the processing capacity.
The product description
At present, it is widely used at home and abroad to separate the suspended substances in the wastewater, and it is widely used in the industrial wastewater treatment such as petroleum, chemical industry, leather making, papermaking, printing and dyeing, electroplating and so on.Air floatation machine is based on the in-depth study of the same type of air floatation device at home and abroad, through the engineering practice, gathered a lot of operating experience, after continuous improvement design.The series devices are equipped with a horizontal reaction chamber and a diversion buffer plate.The method of removing scum is improved to further improve the air floating effect, so it has the characteristics of strong adaptability, stable flow state, drug application and reaction.
The working principle of
Air floatation machine can be used in a variety of wastewater treatment processes, due to the different nature of wastewater, treatment methods and means are different, but the main role in different processes is basically the same.
Taking the commonly used oily wastewater and electroplating wastewater treatment as an example, the following instructions are given:
1. For the treatment of oily wastewater, it is mainly used to remove the emulsified oil in the wastewater. The emulsified oil particles are negatively charged and repel each other.When the emulsified oil is treated by air flotation, demulsifier is added to destroy the structure of the emulsified oil, so that the oil particles can condense and combine with other impurities to form a flocculant.These flocculants float up rapidly under the buoyancy of air floating microbubbles, so as to remove the emulsified oil from the wastewater.
2, used for electroplating wastewater treatment electroplating wastewater mainly contains chromium, nickel, copper, zinc and other heavy metal ions, of which chromium hexavalent is the most serious harm to human.Used air flotation treatment containing hexavalent chromium electroplating wastewater, first into ferrous sulfate in water, make the hexavalent chromium oxide into trivalent chromium, trivalent chromium and other heavy metal ions under the condition of certain PH, metal hydroxide to form insoluble in water, at the same time, the new iron hydroxide and metal hydroxide combined into flocculation body material.These flocculants float up rapidly under the buoyancy of air floating microbubbles, so as to achieve the purpose of removing from the waste water.
The process flow
Wastewater and agents after sewage pump blending into the horizontal reaction chamber, after full reaction chamber into the contact, contact chamber has dissolved air release system, saturated dissolved air water after release release to produce a large number of tiny air bubbles, fine bubbles and waste water after flocculation in combination in the gas floating separation pool, floc under micro bubbles floating bracket, rapid rise, the scum on a regular basis with slag scraper scrape, after separation of water level after entering the system.
