Abstract

The utility model discloses a sludge concentrating sterilizing device with a ultrasonic wave device, which belongs to the sludge concentrating technical field of a sewage treatment project and aims to overcome the defects of high dosage, high expenses, labor-consuming management and operation, possibly caused secondary pollution and the like of the method for putting chemical medicines into a sludge concentrating pond for killing pathogenic microorganisms in the traditional sludge processing process. The sludge concentrating sterilizing device comprises the sludge concentrating pond, a sludge inlet pipe, a sludge discharging pipe and a clear water outlet pipe; the sludge concentrating sterilizing device is provided with the ultrasonic wave device; the ultrasonic wave device comprises a power supply wire, a switch regulator, a ultrasonic wave generator, a lead wire, transducers and the like, which are mutually connected electronically and are fixed through a support; and the power supply wire is connected with the electric supply. The sludge concentrating sterilizing device is simple to operate, is convenient to manage, has the advantages of reliable effect and low running cost and can not cause the secondary pollution. The sludge concentrating sterilizing device is applicable to sterilizing sludge in the sludge concentrating pond.

Description

Be provided with the mud condensed sterilised equipment of ultrasonic unit

Technical field

The utility model relates to the mud condensed sterilised technology in a kind of sewage treatment project, particularly relates to a kind of mud condensed sterilised equipment that is provided with ultrasonic unit.

Background technology

In sewage treatment project, a very important operation is arranged, will carry out the processing of mud.The purpose of sludge treatment is to allow separating that mud and water tries one's best, and reduces the water ratio of mud dramatically, for final processing, utilization, carrying and the storage of mud provides good condition, the harmful poisonous composition of the environment of decontamination simultaneously.Current, that more typical sludge treatment technique has is concentrated, digestion, dehydration etc.Wherein mud is concentrated mainly is to utilize physical method to reduce moisture percentage in sewage sludge, saving mud subsequent disposal expense with dewatering technology of mud, and in general, technical process is comparatively ripe.And sludge digestion technology is comparatively complicated, wherein in order to kill the pathogenic microorganism in the mud, usually will adopt chemical method and biological process.In a lot of sewage treatment projects, determine owing to be subjected to the restriction and the sludge quality in place, adopt and directly in sludge thickener, throw in the technology that chemical agent kills pathogenic microorganism.In mud, throw in the method that chemical agent is killed pathogenic microorganism, though have and save the place, shorten the treatment time, can rationally utilize advantage such as sludge resource, but also exist: dosage is big with can't deny, the expense costliness, management and operational cost expenses of labour power also can cause deficiencies such as secondary pollution.

Summary of the invention

The purpose of this utility model provides a kind of mud condensed sterilised equipment that is provided with ultrasonic unit, it is big to be intended to overcome the existing dosage of method that employing is killed pathogenic microorganism to sludge thickener input chemical agent in the present sludge treatment technique, the expense costliness, management and operational cost expenses of labour power also might cause deficiencies such as secondary pollution.

The utility model is achieved by following technical proposals.

The utility model comprises sludge thickener, mud inlet pipe, shore pipe, clear water vent pipe, be provided with ultrasonic unit, described ultrasonic unit comprises devices such as supply lead, switching regulaor, ultrasonic generator, lead, transverter and is electrically connected mutually, fix by support simultaneously, described supply lead and civil power are connected.In order to make described ultrasonic unit can bring into play the purpose of killing pathogenic microorganism in the mud better, described transverter is arranged in the described sludge thickener, is immersed in the sewage.On the perhaps described transverter horn is housed, described horn is arranged in the described sludge thickener, is immersed in the sewage.

In the utility model, should in low-frequency range, select for use for the frequency of ultrasonic wave band, generally at 20-100kHz.Mud is because of being subjected to action of ultrasonic waves, constantly is compressed and expands, and the cavitation cavitation appears in inside, produces cavitation bubble simultaneously.These cavitation bubbles are constantly being expanded and are being taken place " implosion " under the effect of resonance under hyperacoustic continuous action, produce huge hydraulic shear, at first make in the mud zoogleic physical structure destroyed, make the microbial cell wall also destroyed simultaneously, the stripping from cell of tenuigenin and enzyme reaches the purpose of killing pathogenic microorganism.

Against existing technologies, the beneficial effects of the utility model are:

Simple to operate, convenient management, reliable for effect, working cost is low, does not have the worry that causes secondary pollution.

Description of drawings

Fig. 1 is the structural representation (not adorning horn on the described transverter) of an embodiment of the utility model, and Fig. 2 is the structural representation (on the described transverter horn being housed) of another embodiment of the utility model, and Fig. 3 is that the A of Fig. 1 is to view.Among the figure: 1, supply lead, 2, switching regulaor, 3, ultrasonic wave gives birth to device, 4, lead, 5, transverter, 6, support, 7, sludge thickener, 8, the mud inlet pipe, 9, shore pipe, 10, the clear water vent pipe, 11, horn.

Embodiment

The utility model will be further described below in conjunction with accompanying drawing and embodiment.

The utility model build by figure and installation after can come into operation.At first the mud that water ratio is very big enters sludge thickener 7 from mud inlet pipe 8, after mud is filled, starts ultrasonic generator 3 by switching regulaor 2.The ultrasonic frequency electric energy that ultrasonic generator 3 is produced by lead 4 pass to transverter 5 convert the mechanical energy of ultrasonic vibration to and directly act in the mud as shown in Figure 1 or undertaken by horn 11 that amplitude amplifies as shown in Figure 2 and cumulative after remake and be used for mud.General employing low frequency, high strength, the processing of short period of time can reach the purpose of killing pathogenic microorganism.Through behind the concentration technology, aseptic nontoxic supernatant water can enter water use in water body or the work by clear water vent pipe 10, and lower floor's mud can be discharged by shore pipe 9 do fish feed, fertilizer of crops or further the processing.
