NOVELTY - Water recycling process comprises (i) adjusting the water quality and quantity, placing in the adjustment pool fixed with a spherical filler packet having facultative bacteria culture group, subjecting to denitrification, (ii) adding biological activated carbon filter removing organic compounds in water, aerating (iii) filtering adding oxidants flocculants discharging the resulting sludge (iv) adding polyaluminum, mixing, reacting under high probability of collision, filtering microflocculation products, (v) disinfecting adding sodium hypochlorite, sterilizing and reusing.    USE - The recycled water can be used for road cleaning, urban greening, vehicle washing.    DETAILED DESCRIPTION - Water recycling process comprises (i) adjusting the water quality and quantity reaching the B standard secondary treatment effluent flowing into the sump from the sewage treatment plant GB18918-2002 of town water pollutant discharge standards, introducing the water into a regulating pond via sewage pump to regulate water quality, carrying out water and biological denitrification process, placing in the adjustment pool fixed with a spherical filler packet having facultative bacteria culture group, forming a pre-denitrification biological treatment section, subjecting to denitrification, (ii) adding biological activated carbon filter into the sewage pump through the adjustment pool, passing the water into biological activated carbon filtration tank, culturing aerobic bacteria to adapt to form a segment of aerobic nitrification using activated carbon for the biological carrier, subjecting to nitrification process, removing organic compounds in water, aerating by supplying oxygen using rotary blowers, removing organic matter in the water present in the adjusted pool of pre-denitrification segment, (iii) filtering the water in the oxidation sedimentation tank using biological activated carbon, adding 1-2.5 mg/l or 1-2.5mg / L potassium permanganate, pre-oxidizing and adding 20-30 mg/l inorganic polymer flocculants, flocculating the particles present in the water, removing the precipitated particles along with chemical phosphorus, discharging the resulting sludge to the sludge tank, (iv) lifting the pump to pump out water processed through pre-oxidation and precipitation into micro-flocculation filtration tank, adding 20-30 mg/l polyaluminum according to the water content of the suspension, passing the water into micro-flocculation filtration tank having pressure-type continuously variable vortex reactor water purification device, mixing at speed, setting the shutter at the outlet of the water purification device and changing the direction of flow, breaking the formed large flocks, subjecting the microflocculation particles into micro-flocculation filtration tank having a filter above and clearing the formation of sludge on the filter layer mesh such that the microflocculation particles have more contact area, reacting under high probability of collision, dividing small and dense particles, filtering microflocculation products adsorbed on the filter layer by regularly recoiling the sewage into sludge tank, (v) disinfecting the microflocculation filtered water by passing into the disinfection pool, adding 10-15 mg/l sodium hypochlorite disinfectant, sterilizing, ensuring that the water reaches GB/T18920-2002 urban water recycling standards and reusing.
