Embodiment
To describe the technology contents of technical scheme, construction feature, the objects and the effects in detail, below in conjunction with specific reality
Apply example and coordinate accompanying drawing to be explained in detail.
Refer to shown in Fig. 1, be the structural representation of the utility model preferably embodiment.A kind of animal farm wastewater processing
Device, including the collecting-tank 1, solid-liquid separating machine 2, methane-generating pit 3, anaerobic reactor 4, sedimentation basin 5, inspissator 6, raw being sequentially connected
Thing clarifier-tank 7, filtering ponds 8 and sterilization pool 9, waste water collect by collecting-tank 1, and into solid-liquid separating machine 2, solid-liquid separating machine 2 will
Solid is separated, and remaining waste liquid decomposes by the anaerobic digestion of methane-generating pit 3, after being reacted into anaerobic reactor 4, subsequently into
Sedimentation basin 5, the water outlet of sedimentation basin 5 enter inspissator 6 and concentration are carried out to waste liquid, and the waste water that inspissator 6 is discharged is net by biology
Change pond 7 to purify, filtering ponds 8 filter, and sterilization pool 9 emits after sterilizing.
Collecting-tank 1 is connected with plant by beneath pipeline, caused pig excrements and cleaning plant in plant
Sewage is flowed into collecting-tank 1 from beneath pipeline.The effect of collecting-tank 1 is to collect, store and the water quality and quantity of balanced waste water.Cultivation
The excrement sewage of field discharge, water quality and quantity is usually unbalanced, may be to follow-up waste water if pure and impure waste water does not shunt
Processing unit causes damage, and treatment effect is undesirable.Therefore, the effluent storage by plant's discharge in collecting-tank 1 and makes
Its homogeneous is measured, to ensure the normal operation of subsequent wastewater treatment device.
