A kind of Sewage treatment systems
Technical field
The utility model relates to a kind of oil extraction-generated waste water purification system.
Background technology
Petroleum chemical enterprise is the water rich and influential family, also be the sewage discharge rich and influential family, domestic petroleum chemical enterprise compares with external advanced petroleum chemical enterprise, have larger gap aspect reusing sewage, for example PetroChina Company Limited.'s Liaoyang Petrochemical Company is oil refining, chemical industry and chemical fibre large integrated enterprise, about 130,000 tons of present daily fresh water amount, about 50,000 tons of day discharging industrial sewage, if untimely processing is discharged into river, river, lake, sea, will cause great pollution to environment.
Summary of the invention
The utility model is intended to propose a kind of Sewage treatment systems.
A kind of Sewage treatment systems described in the utility model, comprise settling tank, equalizing tank, filter tank, efficient sedimentation tank and fibrous filtering pool, also be connected with flocculation agent on the described efficient sedimentation tank and add the pond, also be connected with sterilizing agent on the described fibrous filtering pool and add the pond.
A kind of Sewage treatment systems described in the utility model, after industrial sewage is filtered through settling tank, equalizing tank, filter tank, efficient sedimentation tank and fibrous filtering pool successively, the process water that output can utilize again, the use of having saved water, the utility model is simple in structure, and is practical.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment 1.
Among the figure: the 1-settling tank; The 2-equalizing tank; The 3-filter tank; The 4-efficient sedimentation tank; The 5-fibrous filtering pool; 6-flocculation agent pond; The 7-sterilizing agent adds the pond.
Embodiment
Embodiment 1.
A kind of Sewage treatment systems described in the utility model, it is characterized in that described system comprises settling tank 1, equalizing tank 2, filter tank 3, efficient sedimentation tank 4 and fibrous filtering pool 5, also be connected with flocculation agent on the described efficient sedimentation tank 4 and add pond 6, also be connected with sterilizing agent on the described fibrous filtering pool 5 and add pond 7.
Sewage treatment systems described in the utility model, sewage in the heavy pond of secondary is pumped in the equalizing tank 2, after regulating precipitation, 2 pairs of sewage of process equalizing tank enter filtering basin 3, filtered by filtering basin 3, enter efficient sedimentation tank 4 behind the flocculation agent in the sewage adding flocculation agent pond 6 after the filtration, sewage and flocculation agent react in efficient sedimentation tank 4, enter fibrous filtering pool 5 behind the sterilizing agent in the reacted sewage adding sterilizing agent pond 7, with impurity filtering from sewage, water outlet is the process water that can again utilize by fibrous filtering pool 5.
