Description
Technical Field
The invention belongs to the technical field of sewage treatment, and relates to a degassing device for a membrane system.
Background
The reverse osmosis membrane treatment process is one of the most commonly used processes for treating landfill leachate at present, and a reverse osmosis membrane can effectively intercept organic matters and inorganic salts in the landfill leachate (also called stock solution), but has no interception effect on gas dissolved in water, so that produced water after the landfill leachate is treated by the reverse osmosis membrane still contains various gases dissolved in the stock solution, such as carbon dioxide, ammonia nitrogen and the like. For this reason, a degassing tower is often added after the reverse osmosis process to blow off the dissolved gases in the water produced by the reverse osmosis process, especially the dissolved carbon dioxide gas in the water produced by the reverse osmosis process, in order to make the PH of the water produced by the degassing tower reach the relevant discharge standard (typically a PH of 6 to 9 is required). At present, through continuous development, two types of degassing towers emerge, wherein the first type of degassing tower utilizes different gas solubilities under different pressures and temperatures to volatilize gas in liquid by adjusting the pressure and the temperature in the degassing tower; the second type of degassing uses a stripping process, i.e. a flow of water to be degassed is made to flow against a stream of artificially produced air, which, when in contact with the water flow, carries away the gases contained in the water flow. In the current sewage treatment process, a second type of degassing tower is often used, and an alkali neutralization device is added behind the degassing tower to further ensure the removal of carbon dioxide and the reaching of the PH of produced water.
The degasser main scheme of current adoption air stripping principle is for treating the rivers of degasser from last down flowing, and the air is from up flowing down, and the two fully contacts at the packing layer at middle part (the filler main function is let rivers form the water film on the surface of packing to increase the area of contact of rivers and air), and the air is discharged towards the upper end, takes away the carbon dioxide in the rivers when the contact. Meanwhile, a large water tank is arranged at the bottom of the degassing tower, degassed water flows fall into the water tank, alkali is added into the water tank, and water in the water tank is stirred in a circulating mode through an external pump, so that the content of carbon dioxide in water and the PH of produced water are further ensured.
However, in the prior art, the upper degassing device and the lower alkali-adding neutralizing device are independent, so that the overall size and the occupied area of the whole device are increased, and the cost is increased; and secondly, a part of gas blown into the degassing tower by the blower is discharged through a water outlet of the degassing tower, so that the amount of air in contact with water flow at the packing layer is reduced, and the degassing effect is reduced.
