Beneficial effects of the present invention:
1, the present invention is combined using flotation tank, denitrification deep-bed filter, activated coke absorption tower, can be removed in sewage simultaneously
COD, ammonia nitrogen, total nitrogen, total phosphorus and SS, can guarantee the qualified discharge of each index of tail water, it is simple, effectively, stablize.
2, the present invention is in denitrification deep-bed filter, for the defect for overcoming fiber-like wastes of crops itself, in conjunction with tradition
Quartz sand filter media, the preferable haydite of reselection porosity select quartz sand, haydite and fiber-like wastes of crops body as filtrate
Proportion of the product than 3:2:1 realizes the economic stability operation of denitrification deep-bed filter.Quartz sand and haydite, which combine, increases the strong of filtrate
Degree and porosity (porosity increases, that is, increases the bond area of removal total nitrogen microorganism), fiber-like wastes of crops increases hole
While gap rate, carbon source needed for emphasis provides denitrification.Traditional filtrate quartz sand, haydite and fiber-like wastes of crops
Combination the shortcomings that can overcoming traditional filtrate addition carbon source, while the disadvantage for overcoming fiber-like wastes of crops intensity inadequate,
It ensure that outlet effect, and saved cost.
3, activated coke adsorption tower of the present invention is set to after denitrification deep-bed filter, is conducive to absorb fine in denitrification process
The COD that class wastes of crops generates is tieed up, while being adsorbed the COD in sewage by filtering suction-operated, and activated coke pair
The removal effect of ammonia nitrogen is smaller, carries out Adsorption to ammonia nitrogen by zeolite, it can keep two indexes up to standard, improve the association of the two
Same filtration.Using activated coke and zeolite, 4-2:1 is mixed by volume, can remove tail water and the leaching of fiber-like wastes of crops
COD and ammonia nitrogen out guarantee each index emission compliance in tail water.
