Abstract
The invention discloses a biofiltration apparatus, which belongs to the field of environment protection equipment. The biofiltration apparatus comprises a water inlet, a biofilter and a water outlet which are connected together sequentially from the top down, the biofilter is divided into a trickling filtration section and a lixiviation section, the trickling filtration section is located over the lixiviation section, and is divided into at least two layers, each layer comprises at least two separate trickling filtration units which are arranged sequentially from left to right, the lixiviation section is also divided into at least two layers, each layer also comprises at least two separate lixiviation units which are arranged sequentially from left to right, and an air inlet is arranged on the upper end of the trickling filtration section as well. The structure of the biofiltration apparatus is simple and compact, energy consumption is little, the biofiltration apparatus can simultaneously purify sewage and treat odor, the efficiency of removing phosphorus and ammonia nitrogen from sewage is high, energy is saved, and the environmental protection is realized.
Description
Technical field
The present invention relates to a kind of environmental protection equipment, particularly a kind of sewage treatment equipment.
Background technology
Along with more serious contamination, the WWT especially pressure of municipal sewage treatment is increasing.Present WWT usually needs aerator, and aeration when handling the oxygen environment power consumption big, suitable energy-saving and emission-reduction.Simultaneously, present treatment facility is usually very complicated and huge, and equipment cost is high on the one hand, the also not water treatment of suitable various scales on the other hand, and complicated operation is higher to the competency profiling of treatment people simultaneously.
In addition, present sewage work usually in sewage treatment process, because gas purgings such as dioxin are very unpleasant on the one hand, also causes very big threat to HUMAN HEALTH on the other hand, usually needs other equipment to carry out foul smell and handles, and is pretty troublesome.
Summary of the invention
Goal of the invention of the present invention is: the problem to above-mentioned existence provides a kind of new bio straining installation.
The technical scheme that the present invention adopts is such: a kind of biofiltration equipment; Comprise the water-in, biological filter and the water outlet that link to each other in order from top to bottom; Said biological filter is divided into drips filter section and leaching section, drips the filter section and is positioned at leaching section top, and said filter section is divided into two-layer at least; Every layer independently drips the filter unit by at least two and rearranges in order from left to right; Said leaching section also is divided into two-layer at least, every layer also by at least two independently the leaching unit rearrange in order from left to right, said filter section upper end also is provided with an inlet mouth.Sewage get into to drip the filter section from water-in, introduces foul smell from inlet mouth simultaneously, behind foul smell dissolving and the sewage, gets into and drips the filter section and carry out microbial metabolism and handle.After dripping the filter completion, get into the leaching section, the leaching section is flooded fully; After leaching is finished dealing with, discharge from water outlet through the water that purifies.Drip filter section and leaching section and all be divided into several layers, be beneficial to and handle fully, and be divided into several filter unit and leaching unit, can adjust according to the scale of handling, be applicable to the water treatment of various scales, promptly the scope of application increases greatly.
As preferably: leave the gap between the layer of said filter section and the layer, and drip a filter unit and load the dephosphorization filler.Dripping the unitary filler of filter is the bigger filler of particle, leaves the gap between the layer of a filter section and the layer, is beneficial to the prolongation reaction times, is fully reacted, and the ammonia nitrogen in the sewage is oxidized to nitrate salt, simultaneously phosphorus is carried out sedimentation and removes.
As preferably: leave the gap between the layer of said leaching section and the layer, and the leaching unit loads the biological ceramic particle filler.The biological ceramic particle filler can carry out further denitrification denitrogenation with nitrate salt.The unitary filler of leaching is the less filler of particle.
Further: said dephosphorization filler is a Wingdale.
As preferably: said leaching section top one side also is provided with into water arm, and said water inlet arm links to each other with water-in, and the water inlet arm is provided with valve.Through the valve on the control water inlet arm, introduce an amount of sewage supplementary carbon source, thereby help the anti-nitration reaction of leaching section.
In sum, owing to adopted technique scheme, the invention has the beneficial effects as follows: collection WWT and foul smell are handled and one; Guaranteed the healthy of WWT personnel, facility compact is simple, easy handling; High to the removal efficient of harmful elements such as ammonia nitrogen, phosphorus simultaneously, can reach more than 98% ammonia-N removal rate, can reach more than 92% to the clearance of phosphorus; The sewage of the same volume of identical harmful substance contents is handled in environmental protection and energy saving, and the present invention can practice thrift the energy more than 50%.
