Abstract
The utility model discloses a sewage control system, including the sump pit, the exit linkage mechanical bar screen's of sump pit import, mechanical bar screen's export is connected with the intake pump of equalizing basin, and the outlet water pump and the air supporting device of equalizing basin are connected, air supporting device and anaerobism headtotail, the anaerobism system is connected with the anaerobism sedimentation tank, and bio -contact oxidation tank is connected to the anaerobism sedimentation tank, and bio -contact oxidation tank connects secondary sedimentation tank, pond in the middle of secondary sedimentation tank connects, middle pond connection sand filter, air supporting device, anaerobism sedimentation tank and secondary sedimentation tank all be connected with sludge dewaterer, sludge dewaterer connects sludge tihckener. The utility model discloses make the connection between each technology use, go forward one by one layer upon layer for waste water discharge to reach standard, simple structure, reasonable in design, with low costs, economical and practical reduces water waste.
Description
Technical field
This utility model relates to the processing technology field of organic wastewater, particularly relates to a kind of sewage treatment system.
Background technology
Organic wastewater is confined to single Processing tecchnics more, is used in combination with by various Processing tecchnics now, not only changes traditional single administration way, also improves the efficiency of waste water treatment simultaneously.
Utility model content
This utility model purpose is contemplated to make up the defect of prior art, it is provided that a kind of sewage treatment system.
This utility model is achieved through the following technical solutions:
A kind of sewage treatment system, include sump, the outlet of sump connects the import of mechanical grille, the outlet of mechanical grille is connected with the intake pump of regulating reservoir, the water pump that goes out of regulating reservoir is connected with air-floating apparatus, air-floating apparatus is connected with anaerobic system, anaerobic system is connected with anaerobic precipitation pond, anaerobic precipitation pond connects biological contact oxidation pond, biological contact oxidation pond connecting secondary sedimentation tank, secondary sedimentation tank connects intermediate pool, intermediate pool connects sand filter, described air-floating apparatus, anaerobic precipitation pond and secondary sedimentation tank are all connected with sludge dewatering equipment, sludge dewatering equipment connects sludge concentration tank.
Utility model works principle is:
1) waste water passes through mechanical grille after being collected by plant area official website, intercept the biggest solid waste, effectively removing the major part in waste water is the foreign material such as the solid form blood stains, oils and fats and the meat bits that exist, both can guarantee that water pump ran well, and can prevent from again follow-up processing equipment is caused abrasion.
2) it is lifted into regulating reservoir by the water after grid by pump, carries out the regulation of water quality and quantity.Waste water, after homogenizing all amount effects of regulating reservoir, can avoid the impact load to subsequent biochemical technique.
3) water outlet of regulating reservoir is by being pumped into Pressurized dissolved-air floating system, first carries out the regulation of pH, and adds flocculant, and in order to remove SS and oil pollutant, air-dissolving air-float pond carries out solid-liquid separation, and water outlet is delivered in anaerobic reactor process
4), in anaerobic reactor, most COD is removed by the effect of anaerobe；Water outlet after precipitation, enters biological contact oxidation pond
5) in A/O contact-oxidation pool, after anoxia and aeration aerating, most organic substance in the aerobic microbiological Decomposition Wastewater in water, make water quality reach this project discharge standard；Contact-oxidation pool water outlet enters in second pond and carries out mud-water separation
6) secondary clarifier effluent enters intermediate pool；Sand filter processes the water outlet of second pond, removes the suspended particle in water further, it is ensured that the water quality reaching standard discharge of waste water
7) excess sludge of air-flotation system and the excess sludge of sedimentation tank at different levels then enter and carry out concentration in sludge concentration tank, and have pressure filter to carry out processed；It is lifted into regulating reservoir after the supernatant collection of pressure filter, again carries out biochemical treatment.
The utility model has the advantages that: this utility model makes the connection between each technique use, progressive so that discharged wastewater met the national standard, simple in construction is reasonable in design, low cost, economical and practical, reduces water resource waste.
