Embodiment

Embodiment of the present utility model is described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning Same or similar element or element with same or like function are represented to same or similar label eventually.Below by ginseng The embodiment for examining accompanying drawing description is exemplary, it is intended to for explaining the utility model, and it is not intended that to the utility model Limitation.

Pasture waste water treatment process in correlation technique, is that, by the waste water desilting of generation, cleaning up excrement is guided to temporary with after sieving The pool is temporarily stored, then the waste water in the temporary pool is incorporated into Waste Water Treatment handled.Because wastewater treatment difficulty is big, give up The disposal ability of water treatment system is limited, and residence time of the waste water on the temporary pool is very long, often more than 10 days, it is most can Biochemical material is consumed naturally in the temporary pool, and the gas such as hydrogen, biogas, hydrogen sulfide of generation is directly released into air, The significant wastage of the energy is caused, the pollution of waste gas in pasture is also resulted in.

Simultaneously because biochemical material is consumed naturally in the temporary pool in waste water, the difficult degradation degree of waste water continues to increase Plus, the treatable water of Waste Water Treatment is less and less, and the wastewater flow rate on the temporary pool continues to increase, and pool capacity digs bigger and bigger, Ultimately cause an endless loop.

Naturally volatilized with the waste water on the temporary pool, the salinity in waste water gradually rises, the difficult degradation degree of waste water continues Increase, the value of its reuse is also reduced, and further increases the consumption of fresh water, and the water rate for improving pasture is used.

If the waste water in the temporary pool introduces biochemical system, because biochemical system needs to maintain certain water temperature, due to that can give birth to The consumption of compound matter, the heat produced in biochemical treatment of wastewater can not meet the biochemical requirement of Waste Water Treatment, enter One step causes the energy consumption of Waste Water Treatment.

In view of the pasture wastewater processing technology situation in correlation technique, the utility model proposes a kind of disposal ability By force, utilize beneficial to energy recovery and environmental protection, water consumption and energy consumption can be reduced, Waste Water Treatment 1 is useless for pasture Water process.

Below with reference to the accompanying drawings Waste Water Treatment 1 according to the utility model embodiment is described.
