Treatment process of brewing wastewater
Technical Field
The invention relates to the technical field of wastewater treatment, in particular to a treatment process of brewing wastewater.
Background
The air floatation machine is water treatment equipment which generates a large number of micro bubbles in water by an air dissolving system, enables air to be attached to suspended particles in a highly dispersed micro bubble mode, causes the density to be smaller than that of water, and floats on the water surface by utilizing the buoyancy principle so as to realize solid-liquid separation.
The brewing wastewater mainly originates from two processes of cleaning and fermentation liquor distillation in the brewing process, has the characteristics of high concentration of organic matters, more suspended particles, large ratio and the like, and is wastewater which is difficult to treat in the brewing industry.
When the air floatation machine is used for treating the brewing wastewater, because the brewing wastewater has the characteristics of more suspended particles and higher solubility of organic matters compared with common wastewater, scum can be rapidly generated in the treatment process, and a scum accumulation layer is rapidly formed on the liquid level, so that larger work load is brought to a scum cleaning structure of the air floatation machine, the scum cannot be timely and rapidly cleaned out, and meanwhile, the filtering structure inside the air floatation machine is easier to block, thereby bringing negative influence to the wastewater treatment work of the air floatation machine, and the efficiency and effect of the air floatation machine in treating the brewing wastewater are reduced.
