Abstract
The utility model relates to an urban sewage treatment device which comprises a rough filter tank and a reaction tank which are communicated with each other, wherein the a medicine chest is arranged in the position of the reaction tank and is communicated with the reaction tank; a presser is arranged downstream to the reaction tank, and a plurality of layers of filter cloth is arranged at intervals in parallel in the presser; an extrusion mechanism is also arranged in the presser which is communicated with the reaction tank by a drainage pipeline, and all filter cloth is connected in series in the drainage pipeline. The filter cloth in the presser can be washed by dewatering the filter cloth in the extrusion mechanism so as to easily shake off trapped matter on the filter cloth, be extremely convenient to do cleaning operation and ensure the working efficiency of the urban sewage treatment device.
Description
Technical field
The utility model belongs to municipal apparatus field, particularly a kind of device that incity, city sanitary sewage is handled of being used for.
Background technology
Along with the expansion of urban population, the sanitary sewage of living in the city that people produced is also more and more, and this serious threat is to urban residential environment.In some small and medium-sized cities, these sewage generally are Ha Noi without any processing and outside directly being discharged into, and then listen for some sewage that can't discharge and let alone to be trapped in the little river course, and this can cause the smelly of river, and grow a large amount of mosquitos and flies, and the city resident is brought puzzlement in life.In some bigger cities, generally still can handle sanitary sewage.Nothing more than there being two kinds, a kind of is directly sewage to be discharged to outer river by the drainage channel in the mediation city for the processing means of these sanitary sewages; A kind of is to be discharged into outer Ha Noi again after by waste disposal plant sanitary sewage being handled earlier.Known waste disposal plant generally comprises prefiltration pond, reaction tank and finly filtration pond.Because the impurity in the sanitary sewage is more, needs after a period of time the filtrate that is trapped is cleaned in waste disposal plant work, so that its working efficiency can be guaranteed.But existing waste disposal plant exists certain defective when removing filtrate, and its required working hour is many, remove inconvenience, this can badly influence the works better efficient of waste disposal plant.
The utility model content
The utility model technical issues that need to address: a kind of waste disposal plant of being convenient to clean the filtrate of holding back in it is provided.
The technical scheme that addresses the above problem: a kind of urban sewage treating device, comprise the prefiltration pond and the reaction tank that communicate, the position of reaction tank is provided with coupled logical medicine-chest, downstream at described reaction tank is provided with squeezing machine, side by side, be provided with bed filtration cloth in the squeezing machine with being separated by and be used to push the pressing mechanism of these filter cloths, squeezing machine communicates with reaction tank by drainage pipeline, and all filter cloths are connected in the drainage pipeline.Sewage can be trapped in some bigger suspended substances on the filtering layer after by the coarse filtration pond, and injects liquid medicine in reaction tank, can make water through prefiltration by chemical reaction some detrimental impurity be flocculated and precipitates.The water that comes out from reaction tank is in the squeezing machine of flowing through behind the set filter cloth, and these water can be filtered that cloth is smart to be filtered, and the water that obtains after smart the filtration can directly enter outer Ha Noi.For the cleaning of these filter cloths, can after shutdown work, utilize pressing mechanism to make the filter cloth dehydration, jitter filtering cloth can be realized the cleaning of filter cloth then, operation is very easy.
This waste disposal plant can also be done following improvement:
Described reaction tank is provided with motor, and the power input shaft on the motor extend in the reaction tank, is provided with paddle wheel at the inner end of power input shaft.
Described power input shaft is for being obliquely installed, and has angle between the axis of it and reaction tank.
The bottom of described reaction tank is tapered, is provided with in the bottom of reaction tank to lead to extraneous blow-off pipe.
Be provided with the inside and outside scum pipe of communication reaction tank in the position, middle and upper part of reaction tank.
Described prefiltration is provided with the porous dividing plate in the pond, is stacked with cinder on dividing plate, and the bottom of prefiltration pond internal partition is a filtering chamber, and filtering chamber communicates with reaction tank by the posticum of being located on the prefiltration pool wall body.
Compared with prior art, the beneficial effects of the utility model are:
This urban sewage treating device is simple in structure, compact, can save the cost to sanitary sewage disposal.Cleaning for squeezing machine inner filtration cloth; can after shutdown work, utilize the pressing mechanism that is positioned at squeezing machine to dewater; thereby the impurity that sticks on the filter cloth is shaken off, cleaned convenient and simplely, help to guarantee the working efficiency of waste disposal plant.
Description of drawings
Fig. 1 is the vertical profile structural representation of this urban sewage treating device.
Embodiment
See in the accompanying drawing that the structure of this urban sewage treating device mainly comprises three parts, i.e. prefiltration pond 1, reaction tank 6 and squeezing machine 15, reaction tank 6 is between prefiltration pond 1 and squeezing machine 15.
The position, middle and lower part in prefiltration pond 1 is provided with porous dividing plate 3, is shelved with cinder 2 on dividing plate 3, is filtering chamber 4 below 1 internal partition 3 of prefiltration pond, and filtering chamber 4 communicates with reaction tank 6 by the posticum of being located on 1 wall body of prefiltration pond 5.
The top of reaction tank 6 is provided with the medicine-chest 10 that communicates with it, can thorough mixing in order to make liquid medicine in the medicine-chest 10 and the water in the reaction tank, in reaction tank, also establish whipping appts.This whipping appts comprises the motor 11 of being located at the reaction tank oral area, the oblique motor power output shaft 9 that stretches in the reaction tank 6, and the end of power output shaft is connected with paddle wheel 8.The top of reaction tank 6 is right cylinder, rectangular parallelepiped or square, and its underpart is taper.Be provided with and the extraneous blow-off pipe 7 that communicates in the bottom of reaction tank 6, blow-off pipe 7 is used for discharging the throw out at reaction tank 6, and control valve is arranged above it, is in normally off, just regularly opens and carries out blowdown.When adding liquid medicine in reaction tank 6, some organism can be built up together and form floss, and these flosss swim on the interior water surface of reaction tank.Scum pipe 12 inside and outside the position, middle and upper part of reaction tank 6 is provided with the communication reaction tank is provided with dreg collecting slot 13 in the slag notch position of scum pipe 12, and dreg collecting slot 13 is used to collect the flosss of discharging in the scum pipe 12, handles so that unify.
Described squeezing machine 15 is positioned at the downstream of reaction tank 6, communicates by drainage pipeline 14 between them.Has the filter cloth that multilayer is set up in parallel in the squeezing machine 15; these filter cloths are separated from one another to be connected on the drainage pipeline 14; and in squeezing machine 15, has the pressing mechanism that is used for press filtration cloth; when this waste disposal plant shutdown work; pressing mechanism press filtration cloth makes their dehydrations, then behind the jitter filtering cloth; promptly can shake off down adherent trapped substance on the filter cloth, guarantee the filtration efficiency of filter cloth when work.
