The system comprises a water inlet, a water outlet, a sewage draining exit, a PAM dosing device, a PAC dosing device, a coagulation quick-stirring tank, a coagulation slow-stirring tank, a control cabinet, a coagulation sedimentation tank, an intermediate water tank, an effluent tank, a walnut shell filter, an activated carbon filter, a primary precision filter, a secondary precision filter and a sludge processing unit. The coagulation quick-stirring tank, the coagulation slow-stirring tank, the coagulation sedimentation tank, the intermediate water tank, the walnut shell filter, the activated carbon filter, the primary precision filter, the secondary precision filter and the effluent tank are connected in order. According to the invention, the structure of the system is simple; removal rate of suspensions is high; operation is stable and reliable; and floor space is small.
Description
Technical field
The present invention relates to a kind for the treatment of unit of oil field fracturing fluid, particularly relate to the vehicle-mounted treatment system of a kind of inverted discharged pressing crack liquid.
Background technology
Fracturing technology is a major measure of oilfield stimulation.The row's of the returning fracturing waste liquor produced in wellfracturing process, has pollutant component complexity, sediment concentration is high, viscosity is large, COD concentration high.Reuse is continued after current less expensive and safe treatment process process exactly.The vehicle-mounted treatment system of inverted discharged pressing crack liquid is widely used in the process of oil field fracturing fluid.
Summary of the invention
In order to overcome the above problems, the present invention provides that a kind of structure is simple, removal efficiency is high, stable and reliable operation, the vehicle-mounted treatment system of inverted discharged pressing crack liquid that floor space is little.
Technical scheme of the present invention is: this system comprises water-in, water outlet, sewage draining exit, PAM chemicals dosing plant, PAC chemicals dosing plant, coagulation stir pond, coagulation soon and stir pond, housing, coagulative precipitation tank, intermediate water tank, water tank, walnut shell filter, activated charcoal filter, one-level accurate filter, secondary accurate filter and sludge treatment equipment slowly, and described coagulation stirs that pond, coagulation stir pond slowly, coagulative precipitation tank, intermediate water tank, walnut shell filter, activated charcoal filter, one-level accurate filter, secondary accurate filter, water tank connect in turn soon.
Described PAM chemicals dosing plant, PAC chemicals dosing plant are communicated to coagulation respectively and stir pond soon.
Described housing controls stirring velocity and the start and stop of stirring pond soon and stirring pond slowly.
Structure of the present invention is simple, removal efficiency is high, stable and reliable operation, floor space are little, technical process is advanced, and to oil removing in water inlet, to remove removal efficiency high, and water outlet can ensure qualified discharge, vehicle-mounted integral formula design floor space little, without the need to basis, connect water inlet pipe and water outlet pipe can use, simple, convenient, control system PLC controls automatically, level of automation is high, treatment system is packaged type, is movable to have more to carry out sewage disposal, and utilization ratio is high.
