Embodiment Construction

[0015] Referring to the accompanying drawings, the device is composed of an anaerobic baffle reactor 4, an aerobic submerged biological filter 6 and a sedimentation tank 9 which are interconnected in sequence. The anaerobic baffle reactor consists of 3-4 compartments with baffles, partitions, and anaerobic sludge. Each compartment is divided into an upper flow chamber and a lower flow chamber by a baffle 2 and a partition 14. In the flow chamber, anaerobic sludge is added to each compartment, and a dense anaerobic sludge layer is formed in the lower part of the compartment. The first compartment is connected to the distribution tank 1, and the upper part of the first compartment is upward An iron filings packing layer 3 is provided, and a recoil pipe 13 is arranged on the lower part of the iron filings packing layer 3 . The aerobic submerged biological filter 6 is provided with deflectors 5, elastic or semi-soft fillers 7, aeration pipes 12 are arranged at the lower part, and ...

Abstract

One kind method and equipment for life sewage's denitrogenation and dephosphorization belongs to the water treatment domain. The method is that the sewage through obligate baffle reactor obligate sludge layer, spreads the phosphorus on the iron filings padding layer, remove the organic pollutant microorganism in obligate way, the not transformed organic pollutant is degraded in aerobic sunk-style biofilter biomembrane, the ammonia nitrogen transforms to nitrate nitrogen, then is removed again in obligate region by biomembrane counter- nitrobacter, again passes through the precipitation then discharges. The installment is made up of obligate baffle reactor mutually linking and in turn, the aerobic sunk-style biofilter and settling basin. The obligate baffle reactor compose of 3 - 4 baffle in, the partition board, obligate sludge separate room , 1st traverse has the iron filings padding layer, has counter- tube, in the aerobic sunk-style biofilter has the padding layer.

Description

technical field [0001] The invention belongs to the field of water treatment and is suitable for the treatment of urban domestic sewage. Background technique [0002] At present, more than 80% of the urban domestic sewage treatment technology in our country adopts the aerobic activated sludge method, which requires a large amount of aeration, so the investment is large and the energy consumption is high. In recent years, anaerobic treatment of urban domestic sewage has become a research hotspot. However, anaerobic biological treatment has no ability to remove nitrogen and phosphorus, which greatly limits its application in sewage treatment. For the treatment of urban domestic sewage, foreign countries use anaerobic biological treatment + oxidation pond technology to remove part of nitrogen and phosphorus through oxidation ponds, but the oxidation pond covers a large area, which is not suitable for my country's national conditions where there are man...
