In some impurity, so second filter 13 is installed on pipeline 6 between the second shut-off valve 7 and filtering ponds liquid outlet 25,
Ensure that amount impure in extracted water is extremely low with this.
In order to make filtering ponds 2, in flocculation, flocculant comes into full contact with rainwater, in the second filter 13 and second section simultaneously
Only the pipeline 6 between valve 7 bypasses an air blower 15 by three-way connection 14, is installed between air blower 15 and three-way connection 14
There is the 5th shut-off valve 16.In this way when the rainwater during ventilation is needed to make filtering ponds 2 and flocculant are sufficiently mixed, air blower is opened
15, the 5th shut-off valve 16 is opened, closes the second shut-off valve 7.
The top of electrolytic cell 3 is provided with stent 31, an electrolysis unit 32, electrolysis unit 32 are provided on stent 31
Lower part, which is provided with, extends to the anode 321 of 3 bottom of electrolytic cell and cathode 322, and electrolysis unit 32 is powered by external power supply, this is external
Power supply can be solar cell, accumulator or directly connect alternating current.
Surface apposition growth is equipped on the inner vertical direction of biological treatment tank 4 the processing stick 43 of biomembrane；Cause
During for microbiological treatment water, need the life condition for meeting microorganism, i.e., suitable acid-base value, suitable temperature, so
The bottom of biological treatment tank 4 is provided with temperature sensor and pH measuring instruments.Electrical heating is installed on biological treatment tank 4 simultaneously
Stick, while heat-preservation cotton has been wrapped on the outer wall of biological treatment tank 4, the temperature condition of microorganism is met with this；At biology
It manages and is provided with feeding port 45 on the head cover in pond 4, if the pH value in display biological treatment tank 4 changes, at feeding port 45
Put into corresponding neutralize material.At the same time, second air blower 44 is installed at the top of biological treatment tank 4, with this
The pipeline that the air outlet of two air blowers 44 is connected puts in the bottom of biological treatment tank 4, by the second air blower 44 to biological treatment
Air is passed through in pond 4, to meet the aerobic requirement of microbe survival.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
Understanding without departing from the principles and spirit of the present invention can carry out these embodiments a variety of variations, modification, replace
And modification, the scope of the present invention is defined by the appended.
