Embodiment 1
As shown in Figure 1, the present embodiment provides a kind of high ammonia-nitrogen wastewater processing units, comprising: air-floating apparatus, reaction unit, Micro-filtration, ultrafiltration apparatus, film device;Raw water tank water outlet is connected to air-floating apparatus, and the air-floating apparatus waste residue outlet is linked back To raw water tank, the air-floating apparatus water outlet is connected to reaction unit, and sodium hypochlorite transport is connected at the top of the reaction unit Pipeline, the reaction unit water outlet are connected to micro-filtration, and the micro-filtration water outlet is connected to ultrafiltration apparatus, described super Filter device water outlet is connected to film device;The film device outlet is connected separately with ammonium salt reclamation pipeline and water recovery channel;It is first First high ammonia-nitrogen wastewater is removed flocculate and is back in raw water tank by air-floating apparatus, and treated, and water outlet enters reaction unit, Excess NaClO is added in reaction unit, additional amount determines that water outlet passes sequentially through micro-filtration, ultrafiltration apparatus by ORP numerical value, Finally enter film device, film device water outlet can qualified discharge, also recoverable.Other end output ammonium salt solution, can evaporate Recycling.
Its function of air-floating apparatus can remove flocculate, solid, suspended matter, colloid in concentrated water etc., and realize continuous work The equipment make, continuously separated.
Reaction unit determines NaClO additional amount by ORP online, when trend occurs rising suddenly and sharply in ORP, illustrates NaClO excess, Blender is provided with above reactor, bottom is equipped with vortex broken device, can also be to prevent in order to quickly and effectively obtain uniform liquid phase The generation in spin-ended whirlpool, NaClO metering pump and ORP measuring instrument chain control, control the oxidation-reduction potential of inside reactor Stop that sodium hypochlorite is added.NaClO concentration used in reactor is controlled in 25-30%.
For micro-filtration using combined filter element structure, filter core top is that inner core, outer core are made of activated carbon felt reel It is then that charcoal bucket is made in sintering activity charcoal, has water penetration diaphragm to separate between inside and outside core, and inner core is anode, outer core is cathode, this I.e. there are certain suction-operateds for body active carbon, and due to electric field action after energization, adsorption effect is become apparent from;Part under entire filter core It is quartz sand as filler, top and the bottom are isolated with strainer, and needed for combined filter element can meet technique, it is convenient also to simplify process It reliably, while can the backwash of falling pole at any time as needed.
Ultrafiltration apparatus is made of macromolecule resin fiber, and water enters in fiber hollow tube, is discharged from side wall, ultrafiltration membrane There is backwash function, can backwash as needed, clears up dirt.
