Delivering to dewaterer carries out separation of solid and liquid.But the methods such as current mechanism filter-pressing, vacuum filter, investment is high, power drain is big, operation
Complexity, pipeline is easily blocked, thus most of multiple enterprises are reluctant or the powerless treatment for carrying out sludge in sewage, cause sludge to be arranged everywhere
Put, cause secondary pollution, it is impossible to reach elimination pollution, the purpose of environmental protection.
The content of the invention
Object of the present invention is to provide a kind of small investment, low cost is rational in infrastructure, and mud handling capacity is big, solid-liquid point
From the method and its device of the good efficient process sludge dewatering of effect.
To achieve the above object, the technical scheme is that：
A kind of method of efficient process sludge dewatering, it is characterised in that：Methods described is carried out as follows：
1st, the installation of equipment be connected：Dictyosome will be dried and be placed on position beneficial to draining, with connector by the filter of 50-200 mesh
Net is arranged on surrounding and the bottom for drying dictyosome, and the remaining seam of 45-50cm is left on filter screen periphery, with pipeline respectively by sludge condensation
The connection of pond, PAM dissolving tanks, stirring pool and dry net body phase；
2nd, flocculating agent formulation：Water and polyacrylamide are pressed 1000：The ratio of 0.8-1.2 is injected into PAM dissolving tanks, is started molten
Liquid agitator is stirred under being 63-85 revs/min in rotating speed, after stirring, is made mass percent concentration for 0.08-
0.12% flocculant solution；
3rd, material conveying：It is the sludge water of 95-99% by water content in sludge concentration tank, flow is pressed for 10- by sewage sludge feed pump
15m3/h is delivered in stirring pool, while the flocculant solution in PAM dissolving tanks is by PAM measuring pumps, it is 200- by flow
The speed of 500L/h is delivered in stirring pool；
4th, stirring flocculation：Start the agitator of stirring pool, control the rotating speed of agitator for 63-85 revs/min is stirred, work as discovery
When there are a large amount of flocculates to occur in stirring pool, start sludge pump, will be during flocculation material be delivered to and dries dictyosome；
5th, drying and other treatment：Flocculation material in feeding dry net body, its moisture is respectively from drying dictyosome surrounding and bottom 50-200
Flowed out in purpose filter screen, entered in cesspool through water leg, natural air drying took solid sludges after 3-7 days from dictyosome is dried
Go out, pack is transported.
A kind of device of efficient process sludge dewatering, including sludge concentration tank, PAM dissolving tanks, stirring pool, dry dictyosome,
Water leg, cesspool, sewage sludge feed pump, solution stirrer, PAM measuring pumps, agitator, sludge pump, filter screen and connector, it is described
The sludge concentration tank of device is connected built with sewage sludge feed pump, sludge concentration tank material delivery pipe with stirring pool, and material is defeated
Send equipped with sludge pump valve on pipe, PAM dissolving tanks are built with solution stirrer, PAM dissolving tanks solution conveyor tube and stirring pool phase
Connection, is respectively provided with PAM measuring pumps and solution control valve on solution conveyor tube, and stirring pool uses pipeline built with agitator
Connected with dry net body phase, sludge pump is housed on pipeline, dried and water leg is provided with below dictyosome, water leg drainpipe
It is connected with cesspool.
The surrounding for drying dictyosome and bottom with filter screen of the connector equipped with 50-200 mesh, dry the filter of dictyosome bottom respectively
The mud discharging mouth that can be switched is provided with net.
The positive effect of the present invention is：
1st, the filter screen drying sludge groove process is simple used in the method and device, easy to operate, it is not necessary to complicated sludge
Ratio debugging and start operation debugging with PAM solution；
2nd, the method and plant investment are few, low cost.Engineering such as the filter screen drying sludge groove of 400 cubic metres of sewage of day treatment is made
20 yuan of valency, expense 80% can be typically saved than methods such as mechanism filter-pressing, vacuum filters；
3rd, the device using effect is good, and mud handling capacity is big, effectively prevent the secondary pollution of sludge.Such as factory day treatment sewage
400 tons, kilogram/day of the sludge amount of actually occurring 800, sludge need to take up an area 200 square metres without drying and other treatment, after drying and other treatment only
Take up an area 30 square metres, the sludge after desiccation can transport outward utilization.
