Multiple to be spaced apart between flowing plate 132 refering to Fig. 1, two neighboring one in flowing plate 132 is installed on aerobic
The bottom in pond 130, another is installed on the top of aerobic tank 130, in this way, just forming an extension of wriggling in aerobic tank 130
Passage, when sewage enter aerobic tank 130 in when, sewage can be flowed along the passage so that sewage stops in aerobic tank 130
Stay the time longer.Specifically, in the present embodiment, the quantity around flowing plate 132 can be at least three pieces, exemplified by three pieces, first piece
The bottom of the water inlet end of the close aerobic tank 130 of aerobic tank 130 is installed on around flowing plate 132, the 3rd piece is installed on around flowing plate 132
The bottom of the water outlet of the close aerobic tank 130 in oxygen pond 130, and second piece around flowing plate 132 be installed on first piece around flowing plate 132 with
Second piece between flowing plate 132 and second piece of top that aerobic tank 130 is installed substantially at around flowing plate 132, using state shown in Fig. 1 as
Example, and the length direction that the bottom of pond for defining aerobic tank 130 at this time is aerobic tank 130, then around the length and aerobic tank of flowing plate 132
Equivalent width inside 130, so that sewage is only capable of by passing through around the upper end of flowing plate 132 or lower end.
Correspondingly, multiple aerators 131 are installed on the bottom of aerobic tank 130 and around the two sides of flowing plate 132, and are aerated wind
Machine (being to show in figure) is then installed on the outside of aerobic tank 130, and Aeration fan supplies for aerator 131, so that oxygen is dissolved in dirt
In water.Since the passage extends the flow distance of sewage, and aerator 131 also is being installed at the same time in flowing plate 132 so that
Oxygen is more soluble in sewage, so that oxygen-transfer efficiency is improved, so as to which volatile materials or other pernicious gases are accelerated row
Go out.
Refering to Fig. 1, in the present embodiment, the port of export of aerobic tank 130 is connected with the arrival end of coagulating basin 140, coagulating basin 140
Including flocculant dispensing port 145, which connects with the inside of coagulating basin 140 and is used for the input of flocculant,
Coagulating basin 140 is additionally provided with motor 141, agitating shaft 142 and multiple agitating vanes 143.

152 and fine sand filter layer 153 be conducive to strengthen sewage clean-up effect.
In the present embodiment, to improve disinfecting/sterilizing efficiency, thus glass tube 161 and ultraviolet lamp 162 are set.
Wherein, glass tube 161 can vertically or be horizontally arranged in sterilization pool 160, and ultraviolet lamp 162 is then installed on glass
In glass pipe 161, and the both ends of glass tube 161 are sealed.
Further, the quantity of glass tube 161 is more, and the quantity of ultraviolet lamp 162 is multiple, according to sterilization pool
160 specific size, correspondingly, the quantity of glass tube 161 and ultraviolet lamp 162.Glass tube 161 can be along the length of sterilization pool 160
Extend on degree or width, and be divided into multilayer along in the short transverse of sterilization pool 160, so so that 162 energy of ultraviolet lamp
The enough sewage to after processing carries out the irradiation of large area.
To sum up, rational in infrastructure, the highly practical, impact resistance of the sewage treatment unit of the low yield mud is strong, regurgitant volume
Small, stable water outlet, without monitoring, oxygen-transfer efficiency is high, oxidation effect is good, can greatly reduce the volatile materials in sewage, have
Evil gas and Recalcitrant chemicals.
