At present, China paper industry part producer is by building waste water treatment project, effectively reach the effect of waste water control, but, these waste water treatment project costs are very high, general producer can't set up waste water treatment project or keep the continuation of waste water treatment project, therefore, the directly mode of discharging of sewage is still selected by a lot of producers, papermaking wastewater can't reach effective improvement, and water pollution and environmental pollution are serious, and the pollutent that contains in the papermaking wastewater mainly is short fiber, fento, mud and impurity etc., the direct discharging of papermaking wastewater also can cause the waste of fibre resources, therefore, how papermaking wastewater is effectively administered, to reduce to greatest extent the pollution treatment gross investment, recycled fibre pulp, turning waste into wealth is paper industry technician urgent problem.
The utility model content
Therefore, for above-mentioned problem, the utility model proposes a kind of simple in structurely, cost is low, can effectively reach the waste water control effect, reclaims the papermaking sewage treatment system of the fibre pulp in the sewage.
For realizing above-mentioned technical problem, the solution that the utility model is taked is: a kind of papermaking sewage treatment system, comprise settling pit, the coagulation passage, flocculant adding apparatus, settling tank and water collecting basin, described settling pit bottom is provided with the sediment outflow pipe, top is respectively equipped with water-in and water outlet, described settling pit water outlet is connected with the settling tank water-in by the coagulation passage, described coagulation passage is provided with a plurality of flaps that are interspersed, also be provided with the dosing mouth that is connected with flocculant adding apparatus on the described coagulation passage, the bottom of described settling tank is coniform, described settling tank bottom is provided with pulp saver, the water outlet of described settling tank is connected with water collecting basin, the bottom of described water collecting basin is provided with water port, and the top that described water collecting basin is positioned at water port is provided with filtering layer.
Further be: described flocculant adding apparatus is comprised of Scatula, pipeline and valve, and described Scatula is connected with the coagulation passage by pipeline, and described valve is arranged on the pipeline.
Further be: described Scatula is at least 3.
By adopting the aforementioned techniques scheme, the beneficial effects of the utility model are: the papermaking sewage treatment system that designs as mentioned above, papermaking wastewater enters settling pit by the water-in of settling pit, settling pit carries out preliminary sedimentation to papermaking wastewater first, finish separating of papermaking wastewater fiber and sand setting, sand setting is discharged through the sediment outflow pipe; Then, the water of settling pit enters into settling tank via the coagulation passage again, in the coagulation passage, flocculant adding apparatus adds flocculation agent in the current to, flap in current and the coagulation passage collides mutually, and the current raising speed of repeatedly transferring between flap, and the particle collision chance increases in the water, so that fully mix between current and the medicament, coagulation effect is good; In settling tank, rely on gravity fractionation through the water behind dosing, the coagulation, make the fibre pulp that flocculates in the water be deposited in the settling tank bottom, the pulp saver of settling tank bottom reclaims fibre pulp, has effectively realized the recovery of fibre pulp; The water of settling tank flows in the water collecting basin again, and water collecting basin carries out shock absorption to water, and the water of water collecting basin falls other contaminant filters via the filteration of filtering layer, is discharged by water port again; Therefore, via multi task process steps such as sand setting, coagulation, precipitation and filtrations, effectively reached the waste water control effect, reached the emission standard of sewage, and effectively realized the recovery of fibre pulp, described papermaking sewage treatment system one-piece construction is simple, and cost is low, has reduced to greatest extent the pollution treatment gross investment.
