Abstract
The utility model discloses an activated sludge process wastewater treatment system, and belongs to the field of environmentally-friendly equipment. The activated sludge process wastewater treatment system comprises an aerating system, a sedimentation system, a sludge recycle system and a surplus sludge scavenging system, wherein a tube-type aerator is used as the aerating system and comprises a water inlet pipe, an air inlet pipe and an aerator pipe; and the water inlet pipe and the air inlet pipe are simultaneously connected with the same end of the aerator pipe, the aerator pipe is bent and also provided with a mixing chamber, and the outlet end of the surplus sludge scavenging system is also connected with a fermentation tank. According to the utility model, the aerator pipe is designed to be bent, so that the aeration time is prolonged, an aeration effect is improved, the mixing chamber is arranged before waste water and oxygen simultaneously enter the aerating system, the oxygen and the waste water are fully mixed, and the aeration effect is further improved; meanwhile, surplus sludge enters the fermentation tank to ferment, so that organic contaminant can be further disposed; and meanwhile, the organic contaminant can be utilized as farm fertilizers and the like after fermenting, so that the resource utilization is performed.
Description
Technical field
The utility model relates to a kind of environmental protection equipment, particularly a kind of Waste Water Treatment that adopts activated sludge process to carry out wastewater treatment.
Background technology
Active sludge (activesludge) is microbial population and the organic substance that they depended on and the general name of inorganic substance.At present, active sludge is widely used as a kind of method of aerobe processing waste water.Common active sludge processing system generally comprises and comprises aerating system, settling system, mud return-flow system and excess sludge scavenge system; Wherein, Aerating system links to each other with settling system; The settling system exit end links to each other with the excess sludge scavenge system with the mud return-flow system simultaneously, and mud return-flow system exit end also links to each other with aerating system; Waste water at first gets into aerating system; Carry out aerated reaction; Precipitate in settling system then, the general direct discharging of the clear water on upper strata, the mud part of lower floor gets into the mud return-flow system; Continue to pass back into aerating system and sewage hybrid reaction, another part gets into fertility sludge removal system and discharges or landfill disposal etc.In the whole active sludge processing system, aerating system is the most important.Present aerating system is generally aeration tank or aeration tube, because structure itself usually because aeration is not enough, and makes the organism in the waste water not obtain good reaction treatment, and then causes treatment effect bad; In addition, the excess sludge scavenge system directly discharges mud or landfill, usually can not reach environmental requirement, causes secondary pollution.
Summary of the invention
The goal of the invention of the utility model is: the problem to above-mentioned existence provides the sewage treatment equipment that a kind of aeration is abundant, treatment effect is good.
The technical scheme that the utility model adopts is such: a kind of activated sludge process Waste Water Treatment comprises aerating system, settling system, mud return-flow system and excess sludge scavenge system, wherein; Aerating system links to each other with settling system; The settling system exit end links to each other with the excess sludge scavenge system with the mud return-flow system simultaneously, and mud return-flow system exit end also links to each other with aerating system, and said aerating system is a tube aerator; Comprise water inlet pipe, inlet pipe and aeration tube; Wherein, the same end of aeration tube connects water inlet pipe and inlet pipe simultaneously, and said aeration tube is a curved tube.
As preferably: also be provided with a mixing section, said mixing section is between water inlet pipe and aeration tube, simultaneously also between inlet pipe and aeration tube.
Further: the exit end of said excess sludge scavenge system also connects a fermentation vat.
In sum, owing to adopted technique scheme, the beneficial effect of the utility model is: aeration tube is set to curved tube, has prolonged aeration time, has improved the aeration effect; Before waste water and oxygen get into aerating system simultaneously, a mixing section is set, can make oxygen and waste water thorough mixing, further improve the aeration effect; Simultaneously, excess sludge is got into fermentation vat ferment, can further handle organic pollutant, simultaneously can be as agricultural fertilizer after by fermentation etc., make it carry out recycling.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment 1.
Mark among the figure: 1 is water inlet pipe; 2 is inlet pipe; 3 is mixing section; 4 is aeration tube; 5 is settling system; 6 is the mud return-flow system; 7 is the excess sludge scavenge system; 8 is fermentation vat.
Embodiment
Below in conjunction with accompanying drawing, the utility model is done detailed explanation.
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
As shown in Figure 1, the activated sludge process Waste Water Treatment comprises aerating system, settling system 5, mud return-flow system 6 and excess sludge scavenge system 7 and fermentation vat 8; Wherein, Aerating system is a tube aerator, comprises water inlet pipe 1, inlet pipe 2 and aeration tube 4, and aeration tube 4 is a curved tube; Water inlet pipe 1 is connected a mixing section 3 simultaneously with inlet pipe 2; The exit end of mixing section 3 links to each other with the inlet end of aeration tube 4, and the exit end of aeration tube 4 links to each other 5 with settling system, and settling system 5 exit end link to each other with excess sludge scavenge system 7 with mud return-flow system 6 simultaneously; Mud return-flow system 6 exit end also link to each other with water inlet pipe 1, and the exit end of excess sludge scavenge system 7 links to each other with fermentation vat 8.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
