Abstract
The invention relates to a sludge concentration system of a gravity concentration tank. The sludge concentration system comprises sludge lifting pumps and a concentrator, and further comprises flow rate meters, a dynamic stirring tank and a medicament adding device, wherein the dynamic stirring tank is provided with a plurality of sludge inlets which are independent to each other; the dynamic stirring tank is provided with a sludge outlet and a medicament inlet; one sludge lifting pump is connected on each sludge inlet of the dynamic stirring tank by virtue of a sludge inlet pipeline; one flow rate meter is arranged on the sludge inlet pipeline between each sludge lifting pump and the dynamic stirring tank; the sludge outlet of the dynamic stirring tank is connected to the inlet of the concentrator; and the outlet of the medicament adding device is connected to the medicament inlet of the dynamic stirring tank. According to the sludge concentration system of the gravity concentration tank disclosed by the invention, the sludge and the medicaments are stirred and coagulated in the dynamic stirring tank, so that the defects in the using process of the conventional system are overcome, and beneficial conditions are provided for follow-up treatment of the sludge at the same time; and meanwhile, the added medicaments are low in cost and wide in range of application.
Description
Technical field
The present invention relates to a kind of sludge condensation system, the present invention especially relates to a kind of gravity concentration tank sludge condensation system.
Background technology
At present, gravity concentration cell system is mainly used in the concentrated further of mud, is that sewage work carries out one of Major Systems of mud-water separation, as Fig. 1.It is mainly made up of following machine: sludge lifting pump 1 and thickner 2 two portions; Sludge lifting pump 1 by mud by Cemented filling to thickner 2 import, after concentrated, mud waits for that next step process, and filtrate is then directly discharged and entered plant area's pipe network; Due to the certain physical characteristics of mud itself, more or less there is mud extraction water ratio high, the residence time is long, and sludge anaerobic releases the problems such as phosphorus.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of can improve lignin-sludge diversity, reduce mud extraction water ratio and sludge anaerobic can be prevented to release the gravity concentration tank sludge condensation system of phosphorus.
According to technical scheme provided by the invention, described gravity concentration tank sludge condensation system, it comprises sludge lifting pump and thickner, also comprises under meter, dynamic agitation tank and medicament addition device; Described dynamic agitation tank has several separate mud inlets, and dynamic agitation tank has a mud mouth, and dynamic agitation tank has a medicament entrance; Each mud inlet of dynamic agitation tank enters mud pipeline by mud and is connected with a sludge lifting pump, mud between every platform sludge lifting pump and dynamic agitation tank enters on mud pipeline to be provided with a under meter, the described mud mouth of dynamic agitation tank is connected with the entrance of thickner, and the outlet of medicament addition device is connected with the medicament entrance of dynamic agitation tank.
Described sludge lifting pump is that hydraulic fitting submersible sewage pump or dry type install impeller pump.
Driven type thickner centered by described thickner.
Described flow counts magnetic flow meter.
The present invention stirs coagulation by carrying out mud medicine in dynamic agitation tank, overcomes in legacy system use procedure all drawbacks existed, simultaneously for the subsequent disposal of mud provides favourable condition; Add medicament expense low simultaneously; Use range is wide.
Accompanying drawing explanation
Fig. 1 is the structural representation of prior art.
Fig. 2 is structural representation of the present invention.
Embodiment
Below in conjunction with specific embodiment, the invention will be further described.
This gravity concentration tank sludge condensation system, it comprises sludge lifting pump 1 and thickner 2, also comprises under meter 3, dynamic agitation tank 4 and medicament addition device 5; Described dynamic agitation tank 4 has several separate mud inlets, and dynamic agitation tank 4 has a mud mouth, and dynamic agitation tank 4 has a medicament entrance; Each mud inlet of dynamic agitation tank 4 enters mud pipeline by mud and is connected with a sludge lifting pump 1, mud between every platform sludge lifting pump 1 and dynamic agitation tank 4 enters on mud pipeline to be provided with a under meter 3, the mud mouth of described dynamic agitation tank 4 is connected with the entrance of thickner 2, and the outlet of medicament addition device 5 is connected with the medicament entrance of dynamic agitation tank 4.
Described sludge lifting pump 1 is that hydraulic fitting submersible sewage pump or dry type install impeller pump.
Driven type thickner centered by described thickner 2.
Described under meter 3 is magnetic flow meter.
Described dynamic agitation tank 4 is mud medicine mixing device, and the mud inlet that it is arranged is multiple, can connect different sorts mud simultaneously and mix simultaneously, arrange stirrer in tank; Mud inlet arranges flow deflector simultaneously, prevents the short stream of mud; In tank, dosing mouth is set simultaneously, realizes the mixing of mud medicine.
Described medicament addition device 5 is can three slot type chemicals dosing plant and dosing pumps of continuous production liquid.
During work, mud is delivered to dynamic agitation tank 4 by pipeline through under meter 3 by sludge lifting pump 1, meanwhile, in the medicine outlet access dynamic agitation tank 4 of medicament addition device 5, with mud carry out mud medicine stir flocculate twist, the mud flocculated enters in thickner 2 and concentrates, and waits for that next step processes after concentrated after mud discharging, and the filtrate of discharge is then directly discharged and entered plant area's pipe network.By the analog quantity interface adding pump that under meter 3 will enter in the analog signals input medicament addition device 5 of mud amount, thus by the flow that frequency transformer regulates dosing pump to export, finally reach the object of saving medicament.
