Problems solved by technology
[0003] (1) Primary and secondary sewage treatment cannot meet the discharge standard (GB18918——2002)
[0004] (2) The tertiary sewage treatment meets the discharge standard, but the process is complicated, the treatment speed is slow (the biochemical rate of activated sludge is small), the operating cost is high, and the amount of sludge produced is large (sludge bulking), which brings about the treatment of excess sludge.
(3) Large area, equipment investment, huge investment in underground pipe network
(4) Scattered small urban residential quarters and rural settlements cannot realize centralized sewage treatment
The performance of the membrane is reduced and the service life is shortened due to the contamination of the filter membrane, which makes the operating cost and maintenance (replacement of the filter membrane) more frequent

Embodiment Construction
[0019] Water inlet pipe 1 communicates with treatment chamber 4, and in treatment chamber 4, bamboo charcoal layer 2, bamboo charcoal layer 5 are respectively provided with, the height of bamboo charcoal layer 2 and bamboo charcoal layer 5 is slightly lower than the height of treatment chamber 4, bamboo charcoal A jet aerator 3 is arranged between the layer 2 and the bamboo charcoal layer 5; the width of the bamboo charcoal layer 5 is slightly smaller than the width of the treatment chamber 4, and multiple bamboo charcoal layers can be set in the treatment chamber 4.
[0020] On the other side of the bamboo carbon layer 5, an ultrafiltration pipeline 6 is arranged, and the ultrafiltration pipeline water outlet 10 of the ultrafiltration pipeline 6 communicates with the clear water pool 8, and the ultrafiltration pipeline 6 is provided with a pump 11 and a solenoid valve 12. The formed circuit can backwash the ultrafiltration tube in the ultrafiltration pipeline 6; the clear wate...

The invention discloses a processing unit with group craft of jet aeration, bamboo carbon absorption and ultrafiltration yielding water, which is characterized by the following: comprising exhaust pipe, clear-water reservoir, ultrafiltration tube, treating room, fluid jet aerator, bamboo carbon layer, inlet pipe, source of power and controller; connecting the inlet pipe with the treating room; arranging the bamboo carbon layer, the fluid jet aerator and eductor in the treating room; equipping the bamboo carbon layer in the middle part of the treating room; arranging the fluid jet aerator at the one side of the bamboo carbon layer; communicating the air inlet pipe with outdoor; connecting the source of power and the controller; arranging the ultrafiltration tube at the other side of the bamboo carbon layer; communicating the ultrafiltration tube with the clear-water reservoir; arranging pump in the ultrafiltration tube; connecting the source of power and the controller with the pump. This invention possesses small accommodation area, which can resolve the problem of unrealized centralized processing waste water in community of small town and village.
Description
technical field [0001] The invention relates to a sewage treatment device, in particular to a treatment device for treating sewage by a combined process of jet aeration, bamboo carbon adsorption and ultrafiltration suction filtration. Background technique [0002] my country has a large population, which produces a considerable amount of domestic sewage. At present, the treatment of domestic sewage is mainly transported by the urban underground sewage pipe network to the sewage treatment plant, and the traditional activated sludge process is used for centralized treatment. However, the traditional activated sludge process has the following defects: [0003] (1) The primary and secondary sewage treatment cannot meet the discharge standard (GB18918-2002). [0004] (2) The tertiary sewage treatment meets the discharge standard, but the process is complicated, the treatment speed is slow (the biochemical rate of activated sludge is small), the operating cost is high, and the a...
