Filtrate and wastewater treatment equipment system for garbage transfer station

Abstract

The invention discloses a filtrate and wastewater treatment equipment system for a garbage transfer station, and relates to the technical field of waste transfer station wastewater treatment. The filtrate and wastewater treatment equipment comprises an oil separation collection tank, a concentrated water tank, an air floatation device, a middle water tank and a clear water tank, a water inlet pipeline is arranged at the top of the oil separation collection tank in a penetrating mode, and the oil separation collection tank communicates with the interior of the concentrated water tank through afirst water pipe; and a coagulant aid adding device and a coagulant adding device are fixedly mounted at the top of the inner wall of the oil separation collection box. According to the filtrate and wastewater treatment equipment for the garbage transfer station, the filtrate and wastewater of the garbage transfer station can be well treated through cooperative use of a coagulation flotation method and a high-pressure membrane separation method, so that water discharged by the wastewater treatment equipment meets the discharge standard, and no biogas is generated in the treatment process; andtherefore, potential safety hazards caused by biogas are avoided, the safety of the equipment is improved, and residents near the garbage transfer station are protected.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment at a garbage transfer station, in particular to a filtrate wastewater treatment equipment system for a garbage transfer station. Background technique [0002] The garbage transfer station is an important hub for urban garbage collection and treatment, a hub connecting the source of garbage generation and the terminal treatment system, and an essential link in the urban domestic garbage transfer and treatment system. Domestic garbage is initially compressed in the front-end collection station and then transported to the garbage transfer station by garbage truck. After being mechanically compressed in the transfer station, it is transported by garbage trucks to the terminal treatment system. The current terminal treatment system in my country is landfill or incineration for power generation. Wastewater at the garbage transfer station mainly includes domestic wastewater, flushing wastew...

Problems solved by technology

[0003] The existing landfill leachate is usually treated by anaerobic method. Anaerobic biological treatment has many advantages: less energy consumption, simple operation, low investment and operation costs, and less residual sludge generated, but the garbage transfer stations are generally close to In residential areas, the anaerobic method will produce some biogas, which is prone to safety hazards and has low safety
