step two: semi-coke wastewater is stored in a wastewater tank 5, is pumped to the top end of a first reactor 1 by a water pump 6 through a connecting pipe 4, enters through a water inlet 2, flows to the bottom end from the top end of the reactor 1 through internal semi-coke adsorption and filtration, flows to a water storage tank 7 through a sewage discharge outlet 8, is pumped to the top end of the next reactor 1 by the water pump 6 in sequence, and is filtered and adsorbed by the internal semi-coke to remove partial tar, phenol and other impurities in the wastewater, wherein the first and second-stage filtering devices are continuously used for 15-18 days, the third, fourth and fifth-stage filtering devices are continuously used for 20-22 days, and 30-50 tons of semi-coke wastewater is treated every day.

The first and second reactors 1 adopt 5 processing boxes 14, mainly comprising the layer 3 with specification of 0-

The semi-coke with the thickness of 6mm is used as a main filter element for mainly filtering tar in sewage, when the oily sewage enters the filtering device, the granular semi-coke filter element can generate certain resistance to cause the sewage not to be easy to uniformly leak in the filter element, so that the 1 st layer with the specification of 18-

The blue carbon filter element with the specification of 6-18mm on the 35mm layer and the 2 nd layer can filter certain impurities and promote sewage to uniformly leak in the blue carbon filter element with the specification of 0-6mm on the 3 rd layer, and the blue carbon filter element with the specification of 6-18mm on the 6-18mm layer and the blue carbon filter element with the specification of 18-35mm on the 5 th layer are placed on the fourth layer and used for filtering fine blue carbon particles, so that continuous operation of equipment is guaranteed.

The third, fourth and fifth reactors 1 are mainly used for adsorbing phenol and the like in the sewage, and because the sewage after being deoiled by the first secondary filtering device is required to stay in the third, fourth and fifth reactors 1 for 2-4 hours to fully absorb the phenol component in the sewage into the inner structure of the semi-coke, and the longer the stay time is, the better the absorption effect is, therefore, the third and the fourth reactors 1 adopt semi coke with a slightly larger specification as an adsorption material, the upper layer adopts semi coke with the diameter of 6-18mm as a main adsorption material, the bottom layer adopts semi coke with the diameter of 18-35mm to increase the smoothness of water outlet, the fifth reactor 1 adopts mixed semi coke with the diameter of 6-35mm as a main adsorption material, and the main purpose is to adsorb other substances except tar in sewage, and the semi-coke filter element with the bottom layer of 18-35mm is used for filtering fine semi-coke particles and increasing the smoothness of effluent.
