The integrated sewage treatment device schematic diagram shown in fig. 1 comprises an air floatation tank 106, an anaerobic tank 101, an aerobic tank 102, a secondary sedimentation tank 103, a mixed reaction tank 104 and a coagulating sedimentation tank 105 which are communicated in sequence; the air floatation tank 106 is also sequentially communicated with an adjusting tank 107, an oil separation tank 108 and a coking wastewater treatment tank 109; the floating oil discharged from the air floatation tank 106 and the oil separation tank 108 is transported and recycled by the heavy oil outward transportation 113; sludge discharged from the anaerobic tank 101 and the secondary sedimentation tank 103 flows into a sludge concentration tank 110, and is dehydrated and compressed into sludge cake by a dehydrator 111, and transported and recycled by a sludge cake transport 112.
Wherein, the anaerobic tank 101 is provided with a suspension filler A, and the aerobic tank 102 is provided with a suspension filler B.
Specifically, as shown in a physical diagram of the suspended filler A shown in fig. 2, the suspended filler A is polyurethane biological denitrification filler and is square black sponge porous. The suspended filler a is subjected to hydrophilic modification, and in this embodiment, the suspended filler a is impregnated with Sodium Dodecyl Sulfate (SDS) by a surfactant method; and a modified coating is arranged on the surface of the suspended filler A. Further, the modified coating of this embodiment is an activated carbon filler coating, and the material is: activated carbon filler, silica sol and carboxyl modified polymer. The formula comprises the following steps: soaking activated carbon filler in silica sol for a period of time to fully wet the silica sol; then, coating carboxyl modified polymer solution on the surface of the filler to form a film; finally, the film is stably fixed on the surface of the filler through a drying or curing process. In other embodiments, the modified coating may also be a biofilm carrier coating, material: polyethylene dienyl benzene (EDVB) microsphere, silane coupling agent and biomembrane seed strain. The formula comprises the following steps: treating the surface of polyethylene diene-based benzene (EDVB) microsphere by a silane coupling agent to form a coating capable of being combined with a biological film; then, the biofilm seed strain is inoculated on the surface of the coating, and a biofilm is formed by the adhesion and growth of microorganisms. As the suspended filler A is subjected to hydrophilic modification and a modified coating is added on the surface, microorganisms are more easy to attach and grow, and the surface of the carrier is provided with a certain cationic active group and a hydrophilic group, so that the microorganisms and the biological enzymes are firmly fixed on the carrier. More specifically, before biofilm formation, suspended filler a had a specific gravity of 0.95 with water: 1, a step of; after biofilm formation, the specific gravity of the suspended filler A and water is 1:1.
specifically, as shown in a physical diagram of the suspended filler B shown in fig. 2, the suspended filler B is of a multi-pipe hollow structure, is made of polypropylene materials and is manufactured by adopting an integral molding process, and can not be degraded even if soaked in wastewater for a long time, and can not be toxic to microorganisms. The suspended filler B has four layers of frames, 42 long edges and 42 bulges, the structure increases the specific surface area, so that as many biological films as possible are attached to the suspended filler, and the microbial films growing on the surface of the filler are in a high-activity logarithmic growth phase due to fluidization collision of the filler, and the treatment efficiency is high. The suspension filler B is in a suspension fluidization state in an aeration state, so that the impact and cutting of the suspension filler B on bubbles are increased, the utilization rate of oxygen is improved, and the aeration energy consumption is reduced; under the same condition, the aeration can be reduced by 10 percent compared with other structures. More specifically, before biofilm formation, suspended filler B had a specific gravity of 0.95:1, a step of; after biofilm formation, the specific gravity of the suspended filler B and water is 1:1.
further, the aerobic tank 102 is communicated with the secondary sedimentation tank 103 through a water passing pipe, a water passing hole 1 is formed in one end of the water passing pipe connected with the aerobic tank 102, and the aerobic tank 102 is communicated with the water passing pipe through the water passing hole 1. As shown in fig. 4, the water pipe adopts an annular dot matrix perforation water passing method, and the annular water passing holes 1 are formed by annular construction, namely, the water passing holes 1 are formed along the periphery of the cylindrical water passing pipe in a circle. The port of the water pipe connected with one end of the aerobic tank 102 is closed, and the port connected with one end of the secondary sedimentation tank 103 is open. The structural design of the water passing pipe ensures that no dead angle exists in water passing, and water passing is smoother. Preferably, the aperture of the water passing hole 1 is 2mm smaller than the diameter of the suspended filler B, and the aperture of the water passing hole 1 is 20mm.
