Abstract
The utility model relates a semi-aerobic biofilm filter bed of spray-type, belonging to the treatment device of life sewage and organic industrial wastewater. The filter bed consists of a reactor, a spray device, fillings, a filter supporting bed and a baffle. A venthole is equipped at the top of the reactor, whose downside is equipped with a water outlet and a sludge discharge outlet. The fillings in the filter bed is the cracked construction wastes so that sewage flows through the filling layer which has the strong adsorption capacity to degrade the organic contamination by microorganism, no secondary pollution. The utility model has the characteristics of simple structure, high utilization of the biofilm and better treatment effect, without aeration device and seldom blockage. Moreover, the utility model could continuously operate in a long-term with little capital investment and low operation cost, easy for broad application.
Description
Technical field
The utility model relates to the treatment unit of sanitary sewage and organic industrial sewage, belongs to the biologic treating technique field of sewage.
Background technology
Owing to a large amount of dischargings of sanitary sewage, trade effluent, water was seriously polluted in recent years, and the protection of water resources seems particularly important with utilization rationally.Therefore, water treatment and reuse technology are subjected to extensive concern and fast development.At present, sewage water treatment method commonly used both at home and abroad has chemical method, physics method and biological process, and chemical method easily forms secondary pollution, and physics method and biological rule are gradually by usefulness that people like.And biological process is because of plurality of advantages quilt application more and more widely such as it is efficient, non-secondary pollutions.The biological process sewage disposal technology has activated sludge process, but its construction investment is big, working cost is high, and the BAF method progressively is applied in sewage disposal, but still there are a lot of deficiencies at aspects such as operation, working costs, easily stop up as filtering layer, be difficult for back flushing, aeration system is more numerous and diverse.
Summary of the invention
The utility model is the deficiency that overcomes above-mentioned technology, provides a kind of spray-type simple in structure, that cost is low, operation is convenient, treatment effect is good accurate aerobic biologic membrane filter bed.
The utility model adopts following technical solution to realize: the accurate aerobic biologic membrane filter bed of a kind of spray-type, form by reactor, spray equipment, filler, supporting layer, traverse baffle, wherein, the spray equipment that is located at reactor top is made up of waste pipe and shower nozzle, and filler is the construction waste of handling through crushing and screening in the reactor filter bed.Described filler particles increases from top to bottom successively.The top of this reactor is provided with ventilation opening, and water outlet one side of reactor lower part is provided with traverse baffle.
Reactor is that synthetic glass or PVC make.Spray equipment is made up of water inlet pipe and shower nozzle two portions, and water inlet pipe and shower nozzle can be made by PVC.Filler is the construction waste of handling through crushing and screening, plays the effect of biofilm carrier, and its filler particles increases from top to bottom successively.Supporting layer, traverse baffle can adopt synthetic glass, PVC respectively.
During the filter bed operation, sewage enters filter bed by the oxygenation of spout spray, and microorganism when filler breeds at filling surface effluent stream in a large number.After finishing biofilm, the organic pollutant in the sewage is attached microorganism absorption, the degraded on filling carrier, thereby sewage is purified.Because microorganism constantly breeds, rete constantly thickens, on the carrier aged microbial film come off from it with the sewage degradation process in the suspended substance that produces in traverse baffle place precipitation, discharge by mud discharging mouth.
The utlity model has following characteristics:
(1) need not aerator, reduced working cost;
(2) filler utilizes construction waste, has realized the utilization again of solid waste;
(3) packing material size increases from top to bottom successively, has increased the water environment capacity of filtering layer, has reduced the chance of stopping up.
(4) simple in structure, capital cost is low, be convenient to sizable application;
(5), do not produce secondary pollution by the biological degradation organic pollutant.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Among the figure: 1, reactor, 2, spray header, 3, filler, 4, supporting layer, 5, traverse baffle, 6, mud discharging mouth, 7, water outlet, 8, ventage.
Embodiment
Embodiment: structure is made up of 1 reactor, 2 spray headers, 3 fillers, 4 supporting layers, 5 traverse baffles, 6 mud discharging mouths, 7 water outlets, 8 ventages as shown in drawings.Reactor 1 is that synthetic glass or its upper end of PVC structure are provided with ventilating pit 8 and spray header 2, the air contact fully that spout upwards can make current be entered by ventilating pit like this reaches the purpose of aeration, filler 3 is construction waste (being made through fragmentation by brick or concrete) in the filter bed, effluent stream is through packing layer, filler has stronger adsorptive power, microorganism just breeds in a large number at filling surface, after progressively finishing biofilm, organic pollutant in the sewage is adsorbed to biofilm surface, through microbiological deterioration, the suspended particle that this process is produced, because the particle diameter of filler increases from top to bottom successively, the filtering layer lower space is big, and the part suspended particle flows through 4 bearing beds with water is discharged by 6 mud discharging mouths after the barrier effect of 5 traverse baffles deposits, and the water after the purification is then discharged by 7 water outlets.Because the special proportioning of filter bed filler particle size makes this depth filtration, deep bed filtration effect strong, water outlet is more clear than the water outlet of general filter bed, and more general filter bed is easy when back flushing.
