Description
Technical field
The present invention relates to a kind of environmental protection equipment, especially be applicable to the wastewater denitrification treatment apparatus of the processing of ammonia nitrogen in the trade effluent.
Background technology
Ammonia nitrogen is the water body main nutrient, and main source is the discharging of rainwash, sanitary sewage and trade effluent.In industrial pollution source, the waste water of industry such as coking, inorganic and organic chemical industry and percolate etc. all have the characteristics of high-concentration ammonia-nitrogen.High-concentration ammonia nitrogenous wastewater can not generally adopt the vapor distillation denitrogenation at present with conventional biologic treating technique, and its running cost is high, and increases a large amount of waste water.
Processing thinking to high-concentration ammonia nitrogenous wastewater mainly contains two at present: the one, reduce the ammonia nitrogen concentration in the waste water, thereby the nutritive proportion in the adjustment waste water (C/N), make waste water can directly enter biological processing unit and realize high efficiency treatment effect, mainly comprise various physico-chemical processes denitride technologies; The 2nd, the improvement of existing biologic treating technique and the exploitation of true tumor treatment process make microorganism can carry out series reaction such as nitrification and denitrification smoothly, make the ammonia nitrogen in the waste water finally change into harmless nitrogen discharge, realize the efficient removal of ammonia nitrogen.
The physical chemistry denitride technology mainly utilizes physics and the chemical action between the material to remove with ammonia nitrogen or with redox reaction or in the mode of sorption extraction.Because this technology directly enters the subsequent biological treatment unit with ammonia nitrogen removal again after to a certain degree, thereby optimized the nutrition ratio in the waste water, can improve the unitary organism of subsequent biological treatment and handle load, increase the operation stability of biosystem, reduce the complicacy of biosystem debugging and operational process.The physical chemistry denitride technology mainly includes break point chlorination, chemical precipitation method, absorption method, ion exchange method, the gentle formulation of blow-off method, liquid-film method, electroosmose process, catalytic wet air oxidation etc.
Though above a lot of method can both be removed the nitrogen in the water effectively, all exists some shortcomings.Break point chlorination directly utilizes the oxygenizement of chlorine to remove ammonia nitrogen in the waste water, and the chlorine dosage is big when ammonia nitrogen concentration is high, the working cost height, and when have organism in the waste water, have the risk of production organochlorine secondary pollution; Chemical precipitation method mainly utilizes the insoluble of some composite salt of ammonia that ammonia precipitation is removed, and when ammonia nitrogen concentration was higher, the same existence added the big problem of dose; Absorption method and ion exchange method are subjected to the restriction of material absorption (or exchange) capacity, also only are fit to the processing of low ammonia nitrogen concentration, and the organism that material is subject in the waste water disturbs its also more complicated of regenerating; Blow-off method and vaporizing extract process require the pH value of waste water higher, and it is big to add alkali number, and corresponding aeration machinery energy consumption and steam consumption are also than higher, and the treatment effect instability pollutes atmosphere easily; Electroosmose process requires membrane module that ammonium ion is had stronger selectivity, and membrane module also pollutes than being easier to receive the machine thing; Catalytic wet air oxidation is owing to High Temperature High Pressure, so equipment is had higher requirement.
Summary of the invention
Problem to be solved by this invention provides a kind of wastewater denitrification treatment apparatus, and this wastewater denitrification treatment apparatus is simple in structure, and treatment effect is better, pollutes little and cost is low.
Technical scheme provided by the invention is: a kind of wastewater denitrification treatment apparatus, comprise waste water reactor, and waste water reactor has water-in, water outlet and air outlet; Be provided with the aeration tube of taking pore out of in the waste water reactor, aeration tube has the inlet mouth with waste water reactor source of the gas UNICOM outward; Be provided with the casing of built-in microwave source, cabinet wall is equipped with microwave generator, and waste water reactor runs through casing.
Be provided with the microwave leakage safety guard around the slit between above-mentioned waste water reactor and the casing.
Above-mentioned microwave leakage safety guard is to be located at around the slit and around the iron sheet protective layer of waste water reactor.
Above-mentioned waste water reactor is a glass reactor.
Above-mentioned waste water reactor is provided with the overvoltage venting port.
The water-in of above-mentioned waste water reactor and air outlet are located at the waste water reactor upper end, and water outlet is located at the waste water reactor lower end.
Beneficial effect of the present invention:
The present invention provides a kind of materialization of economical and efficient to handle new installation for the denitrogenation processing of China's ammonia nitrogen in high density trade effluent, and ammonia nitrogen in waste water concentration significantly reduces after the denitrogenation, helps follow-up biochemical treatment.Relatively have reduced investment with existing denitrogenation of waste water technology, advantages such as working cost is low, occupation area of equipment is little, processing efficiency is high, convenient management.Can reach life reuse water standard after the microwave treatment, reproducible utilization is in additional underground water source, process water, agricultural water, cities and towns miscellaneous water (afforestation, flush the toilet, street cleaning, vehicle flushing, building operation, fire-fighting) etc., if further advanced treatment can reach present city tap-water standard.This equipment has good market and uses and industrialization prospect.
The present invention is simple in structure, and treatment effect is good, pollutes little and cost is low.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
Embodiment
Referring to accompanying drawing, the present invention includes the casing 7 of waste water reactor 2 (as glass reactor) and built-in microwave source, at casing 7 inwalls microwave generator 5 is housed, the perpendicular cylinder type glass reactor 2 of putting in the middle of the casing 7, glass reactor stretches out casing in two ends about in the of 2, one aeration tube 10 is arranged in the glass reactor 2, offers several production wells 8 on the aeration tube 10, inlet mouth 3 ends of aeration tube 10 from the glass reaction wall stretch out be used for glass reactor 2 outside source of the gas UNICOM.Described glass reactor 2 upper ends have inlet mouth 3 (aeration tube inlet mouth), water-in 9, venting port 11 (overvoltage venting port or emergency situation venting port) and ammonia to reclaim mouthful 1 (a waste water reactor air outlet).There is a water outlet 6 described glass reactor lower end.In order to prevent microwave leakage contaminate environment and infringement people's health, the present invention's suggestion is provided with the microwave leakage safety guard, as iron sheet protective layer 4 being set on every side and around waste water reactor in the slit.
