Embodiment 1
[0027] Such as figure 1 Shown is the integrated sewage treatment equipment of the present invention.
[0028] The equipment includes anaerobic zone 2, anoxic zone 6, aerobic zone 4, and precipitation zone 8; anaerobic zone 2 and anoxic zone 6 are connected by an inverted U-shaped tube; aerobic zone 4 and anoxic zone 6 are combined into One body, the top is an aerobic zone 4, the bottom is an anoxic zone 6, and the middle is separated by a folded plate 5; the anoxic zone 6 is provided with a stirring device 7, and the aerobic zone 4 contains an aeration device 3. The combination of anaerobic zone 2, anoxic zone 6, aerobic zone 4, and precipitation zone 8 is called a functional zone.
[0029] Precipitation zone 8 adopts inclined plate for precipitation, and the inclination angle of the inclined plate is 45° relative to the horizontal plane.
[0030] The aeration device 3 is a portable fiber hose aeration device.
[0031] The integrated sewage treatment equipment also includes...
Embodiment 2
[0034] Such as image 3 As shown, the present invention provides a device diagram of high-efficiency phosphorus removal sewage treatment equipment, which is carried out in a laboratory, and the effective volume of the test device is 40L. The test sewage is sewage from a city in Jiangsu Province, and its influent water quality is shown in Table 1. During the test period, the temperature of the mixed liquid in the reactor changed with the seasons, and was basically maintained between 11 and 28°C. At the beginning of the test, the treated water volume was 0.30L / h, and then slowly increased to 6L / h. The sludge concentration is maintained at 2.2-4.3g / L, and the sludge load is 0.07-0.12kg·BOD 5 / kg VSS d.
[0035]The far left of the functional area of the sewage treatment equipment of the present invention is the anaerobic area, and the hydraulic retention time is controlled at 15h. U-shaped pipes are used to communicate between the anaerobic area and the aerobic area; the aero...
Embodiment 3
[0037] Sewage first enters the grid, intercepts and removes coarse suspended matter and floating matter in the sewage; then passes through the regulating tank, and uses sodium bicarbonate solution to control the pH at 7-8; deal with. Conducted in the laboratory, the effective volume of the test device is 40L.
