Description

TECHNICAL FIELD

[0001] The present application relates to the field of industrial wastewater treatment, in particular to an adsorption system for treating industrial wastewater. BACKGROUND

[0002] The iron-containing waste hydrochloric acid meeting the access standard but exceeding the technical index of the acid mother liquor is pumped into a continuous reactor composed of three 35m³ reaction tanks in series, activated carbon powder is added in the first reaction tank, a heavy metal capturing agent is added in the second reaction tank, the acidity is adjusted to be less than 5%, hydrogen peroxide is added according to the remaining organic matter, the organic matter in the waste hydrochloric acid is converted into inorganic salt, water and a small amount of carbon dioxide by Fenton reaction, calcium chloride is added according to the concentration of fluoride ions to remove the fluoride ions, and after filtration by a diaphragm filter press, if the pretreatment standard is met, the waste hydrochloric acid is directly pumped into an intermediate storage tank of waste acid. If the indexes such as organic matter, heavy metals, total nitrogen and total phosphorus exceed the pretreatment standard, the waste hydrochloric acid is pumped into a resin adsorption system for adsorption and removal until the harmful indexes meet the standard, and then the waste hydrochloric acid is pumped into the intermediate storage tank of waste acid. The existing adsorption system often needs to pass through an organic matter adsorption device, a heavy metal adsorption device, a total nitrogen adsorption device and a total phosphorus adsorption device in turn, and finally enters the intermediate storage tank of waste acid. However, sometimes after filtration by the diaphragm filter press, some indexes are qualified, so passing through the organic matter adsorption device, the heavy metal adsorption device, the total nitrogen adsorption device and the total phosphorus adsorption device is not only a waste of time, but also a waste of resources.

[0067] The working principle of the adsorption system for treating industrial wastewater according to the first embodiment is as follows:

[0068] The switching component drives the vertical support rod to rotate by a certain angle so that the filter holes of the upper filter plate 15, the lower filter plate 16, the top sealing filter plate 21, the upper sealing filter plate 22 and the lower sealing filter plate 23 are in one-to-one correspondence. At this time, the wastewater retained in the lower adsorption chamber 102 is discharged downward, the wastewater retained in the upper adsorption chamber 100 enters the lower adsorption chamber 102 downward, and the wastewater on the upper adsorption chamber 100 enters the upper adsorption chamber 100; then the switching component drives the vertical support rod to return to the original position, and the filter holes of the top sealing filter plate 21, the upper sealing filter plate 22 and the lower sealing filter plate 23 are staggered with the filter holes of the upper filter plate 15 and the lower filter plate 16.

[0069] When the resin needs to be desorbed and regenerated, the pair of upper feed hole sealing rings 37 rises, the upper feed hole 3310 is opened, and then the electromagnetic valve on the discharge conduit 17 is opened. The resin in the upper adsorption chamber 100 and the lower adsorption chamber 102 enters the inside of the pair of ring seat bodies 331 along the discharge conduit 17, and then the desorption liquid is sprayed to the resin in the pair of ring seat bodies 331 through the liquid inlet pipe 341 and the liquid inlet nozzle 34. After a period of time, the liquid outlet pipe 39 is opened, and the desorption liquid is discharged along the liquid outlet pipe 39. After desorption of various different liquids, the pair of ring seat bodies 331 rises so that the lower discharge hole 3312 is opposite to the feed conduit 18, and then the pair of lower discharge hole sealing rings 38 descends so that the lower discharge hole 3312, the discharge communication hole 380 and the feed conduit 18 are communicated. In this way, the resin particles in the pair of ring seat bodies 331 return to the upper adsorption chamber 100 and the lower adsorption chamber 102.
