Description

Sludge treating system
Technical field
The present invention relates to field of sludge treatment, particularly relates to a kind of sludge treating system.
Background technology
In recent years, paint industry was fast-developing, and coating wastewater increases therewith, and its sludge yield also constantly rises.With Environmental requirement is increasingly strict, and the innoxious of sludge, minimizing, resource become inevitable development trend, and sludge dewatering is dirty The premise of mud final disposal.At present, domestic and international coating wastewater device for dehydrating sladge waste mainly has filter press and the dehydration of folded spiral shell formula Machine, due to coating wastewater sludge viscosity it is big, during filter press process filter cloth easily block, operation management trouble, especially when Sludge oil content is difficult to form filter cake when high, and folded spiral shell formula dewaterer has, and muddy water is easily separated, be not easily blocked and energy is automatic continuous The features such as operation, develop rapidly and popularize in paint industry, gradually substitute plate and frame type filter-press in the application.Folded spiral shell formula dewaterer Though being better than filter press with performance in coating wastewater Treatment of Sludge, operationally yet suffer from dewatering rate and pay no attention to Think, clean not thoroughly and the deficiency such as operating cost is higher, still need to constantly improve.
The content of the invention
The present invention proposes a kind of sludge treating system and handling process, and in solving prior art, dewatering rate is paid no attention to Think, clean not thoroughly and operating cost is higher etc. problem.
The technical scheme is that what is be achieved in that:
Sludge treating system, the system include sludge-tank, reaction tank, folded spiral shell formula dewaterer, filtrate storage pool and control System, is provided with elevator pump in the sludge-tank, the elevator pump is by reaction tank described in the sludge suction inside the sludge-tank Portion, the Single port in the reaction tank are connected with a medicine system, and the reaction tank another port is connected with folded spiral shell formula dewaterer; The folded spiral shell formula dewaterer is also associated with backwashing system.
As the preferred version of the present invention, a dosing pump and a medicine storage device inside the medicine system, are provided with.
Used as the preferred version of the present invention, the dosing pump is linked with the elevator pump, commonly through control system control Folding.
As the preferred version of the present invention, in the folded spiral shell formula dewaterer, an auger axle, the auger are provided with Axle external stability has multiple lamination of living admittedly.
Used as the preferred version of the present invention, the folded spiral shell formula dewaterer is connected with filtrate storage pool.
Used as the preferred version of the present invention, the backwashing system includes a recoil water pump, and recoil water pump is located at the filter On liquid storage pool, counter-flushing process is completed by folding in spiral shell formula dewaterer described in the liquid suction in filtrate storage pool.
Beneficial effects of the present invention, sludge treating system, system include sludge-tank, reaction tank, folded spiral shell formula dewaterer, filtrate Storage pool and control system, are provided with elevator pump in the sludge-tank, the elevator pump is by the sludge suction inside the sludge-tank Inside the reaction tank, the Single port in the reaction tank is connected with a medicine system, and the reaction tank another port is connected with Folded spiral shell formula dewaterer;The folded spiral shell formula dewaterer is also associated with backwashing system.Optimization flocculant species (Calx, ferrous sulfate, Between PAC, PAM preferably) and dosage, rinsed with filtrate replace tap water to rinse, that (0.1% sulfuric acid solution) etc. is rinsed in dosing is square Formula, effectively improves the sludge dewatering efficiency of folded spiral shell formula pressure filter, makes cleaning more thorough, while rinse dosage is reduced, so as to reduce Operating cost, realizes the efficient process of coating wastewater sludge.
Description of the drawings
In order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing Accompanying drawing to be used needed for having technology description is briefly described, it should be apparent that, drawings in the following description are only this Some embodiments of invention, for those of ordinary skill in the art, without having to pay creative labor, may be used also To obtain other accompanying drawings according to these accompanying drawings.
Fig. 1 is present configuration sketch.
In figure, sludge-tank 1, elevator pump 2, reaction tank 3, medicine system 4, folded spiral shell formula dewaterer 5, filtrate storage pool 6, recoil Water pump 7.
Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than the embodiment of whole.It is based on Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made Embodiment, belongs to the scope of protection of the invention.
Embodiment 1
Sludge is promoted to reaction tank by elevator pump, adds appropriate Calx (20mg/L) and PAM in reaction tank respectively (80mg/L) to change mud granule structure, the stability of colloid is destroyed, improves dewatering performance of sludge, improved dehydrating effect and take off The production capacity of wetting system.
Feeding lime and the reacted sludge of PAM flow into folded spiral shell formula dewaterer, when auger axle is rotated, are located at promotion The multiple lamination relative movement of living admittedly of axle periphery, under pressure, water is leached from the lamination gap of relative movement, is realized dirty Mud concentration, dehydration.
When folded spiral shell formula dewaterer need to be cleaned, using the dewaterer filtrate in recoil water pump lifting filtrate storage pool to multiple solid Lamination living is rinsed.
When folded spiral shell formula dewaterer need to be cleaned, moderate amount of sulfuric acid (0.1% solution) is added toward dewaterer filtrate, it is stifled to dissolve Particulate matter of the plug in filter gap, it is ensured that cleaning performance.
Embodiment 2
Such as the processing scheme in embodiment 1, wherein, feeding lime 20mg/L in reaction tank, ferrous sulfate 80mg/L are changing Become sludge grain structure, destroy the stability of colloid.When folded spiral shell formula dewaterer need to be cleaned, add toward dewaterer filtrate appropriate Sulphuric acid (0.2% solution), to dissolve the particulate matter being blocked in filter gap, it is ensured that cleaning performance.
Embodiment 3
Processing scheme such as in embodiment 1, wherein, add PAC70mg/L to change mud granule structure in reaction tank, break The stability of bad colloid.When folded spiral shell formula dewaterer need to be cleaned, moderate amount of sulfuric acid (0.3% solution) is added toward dewaterer filtrate, To dissolve the particulate matter being blocked in filter gap, it is ensured that cleaning performance.
Presently preferred embodiments of the present invention is the foregoing is only, not to limit the present invention, all essences in the present invention Within god and principle, any modification, equivalent substitution and improvements made etc. should be included within the scope of the present invention.
