Description
Technical field
The utility model belongs to the environmental protection equipment technical field, is specifically related to the wastewater treatment equipment that a kind of deamination and ammonia nitrogen reclaim, particularly blue charcoal sewage treatment equipment.
Backgroundfield
Blue charcoal waste water is the waste water that produces in coal system semicoke product and the quenching process, its COD, BOD, SS, phenol, NH
3-N, wet goods content are very high, and complicated component is changeable, and wherein organic pollutant is main with phenol compound, accounts for the over half of total organic matter, secondly also comprise the heterogeneous ring compound of polycyclc aromatic compound and nitrogenous, oxygen, sulphur etc.; Inorganic pollutant is main with prussiate, sulfide, ammonium salt mainly.Blue charcoal waste water is a kind of typical high-concentration organic sewage difficult to degrade, and intractability is very big.
Difference according to coking industry investment and production mode; Coking chemical waste water is divided into two kinds of the lighter metallurgical coke of pollution (coke) waste water and with serious pollution semicoke (blue charcoal) waste water; The production of the extensive property of metallurgical coke is in the majority, and investment puts in place, and the sub product (coal tar, coke(oven)gas, crude benzol etc.) that is produced in the production process has been carried out comprehensive recovery and utilization; Therefore; Pollutent obviously reduces in the waste water of its generation, and such waste water is general only through carrying out biochemical treatment after the simple pre-treatment (oil removal and water quality and quantity are regulated), realizes standard wastewater discharge or recycling.Semicoke is blue charcoal, is raw material because it adopts non-caking coal and weakly caking coal, the production technique of middle low-temperature pyrolysis; Add production-scale limitedly, the deficiency of investment does not comprehensively reclaim and utilizes the sub product in the production process; Therefore; The a large amount of poisonous and hazardous material that produces in its process of coking all is dissolved in the waste water, makes such contaminated wastewater substrate concentration quite high, has also improved the intractability of such waste water simultaneously greatly; At present, blue charcoal waste water has become one of used water difficult to degradate of generally acknowledging both at home and abroad.
Blue charcoal waste water contains the ammonia nitrogen of high density; If do not handle; Follow-up processing is brought certain influence; Simultaneously a large amount of ammonia nitrogen waste waters enter water body not only to be caused body eutrophication, causes water body black smelly, and will increase difficulty and the cost of giving water treatment, even crowd and biology are produced toxic action.Generally can handle back qualified discharge or reuse in the industry to ammonia nitrogen waste water.Technological method commonly used has chemical precipitation method, ion exchange method, break point chlorination method, biological process etc.Chemical precipitation method is difficult to control to the dosage of phosphoric acid salt and magnesium salts, causes exceeding standard of phosphorus easily simultaneously, follow-up processing has been increased certain load, and the relative blow-off method of processing costs is higher.Ion exchange method and break point chlorination method cost of investment are big, and treatment of high concentration waste water is poor, are difficult to control during dosing.If carry out biochemical treatment, be prone to cause into that C/N reduces in the water, want to obtain good nitrated and denitrification effect; Just must extra increase carbon source and increase basicity; And the ammonia nitrogen of high density itself has restraining effect to activity and the breeding of mikrobe, and biological ammonia nitrogen removal technology also exists floor space big, and investment cost is high; The low temperature aging rate is low, is subject to the shortcoming such as influence and operational management trouble of toxic substance.
The utility model content
The technical problem that the utility model solved provides a kind of deamination that both can be used for; Can be used as the waste disposal plant that ammonia nitrogen reclaims again, high to solve the cost that exists in the prior art, investment is big; It is serious that ammonia nitrogen reclaims the secondary pollution that causes, the complicated problem rambunctious of operation of equipment.
For solving above-mentioned technical problem, the technical scheme that the utility model is taked:
The wastewater treatment equipment that a kind of deamination and ammonia nitrogen reclaim comprises tower body, and the top of tower body is provided with the air outlet; The outer wall of tower body bottom is provided with rising pipe, inlet pipe; The outer wall on tower body top is provided with water inlet pipe, also comprises air water combination layer, water distributor, packing layer, guide water board, gas block panel, and water inlet pipe is communicated with the water distributor that is connected into by several nozzles that is horizontally set on the tower body inner chamber; The water distributor upper end is provided with the air water combination layer; The water distributor lower end is provided with packing layer, and the bottom of packing layer is provided with guide water board, and the guide water board bottom vertically is provided with gas block panel near a side of rising pipe.
Constitute the cloth gas area between the bottom of above-mentioned guide water board bottom and tower body inwall, rising pipe, inlet pipe are all and the connection of cloth gas area.
The xsect of the guide water board of last water is a trilateral, and the radial direction of guide water board is provided with the guiding gutter of matrix, and guide water board is provided with several pores.
Compared with prior art; The utility model can also can reclaim ammonia by deamination; On cost, reduce greatly, operational administrative is simple, and it has strengthens the water distribution that atomizes, spilling water separation obstruct, filler contact diffusion, gas-water separation receipts water, the recovery of gas-water separation waste gas, homogenizing air distribution function; Wherein ammonia nitrogen removal frank is greater than 90%, and the water recovery is greater than 95%.
