Description
Technical field
The present invention relates to method and device that a kind of SBR+SBBR municipal effluent high-performance bio based on Anammox is processed, belong to dirty water living creature processing technique field.
Background technology
Body eutrophication is day by day serious, and in sewage, the discharge of nitrogen phosphorus is to cause its major reason.The removal of nitrogen and phosphorus pollutants has become the key issue of sewage disposal and regeneration.In the < < urban wastewater treatment firm pollutant emission standard > > (GB18918-2002) that China promulgates for 2002, requiring all pollutant discharging units effluent quality is that ammonia nitrogen is less than 5mg/L, total nitrogen is less than 15mg/L, and sewage work's total phosphorus of building after on January 1st, 2006 is simultaneously less than 0.5mg/L.The energy consumption of existing sewage work is very high, and wherein a lot of sewage disposal plant effluent water quality can not reach first discharge standard, need to carry out upgrading.How when realizing high-efficient denitrification and dephosphorization, to reduce water treatment energy consumption, reduce processing costs, for the Sustainable development important in inhibiting of sewage disposal.
The microorganism that biological phosphate-eliminating is mainly referred to as polyP bacteria by a class completes.Active sludge is alternate run under anaerobic and aerobic state, and in mud, polyP bacteria discharges phosphorus under anaerobic state, under good oxygen condition, excessively absorbs phosphorus; Through the rich phosphorus excess sludge of discharge, its result is compared with traditional activated sludge process, can efficiently remove the phosphor contaminant in sewage.SBR technique is alternate run under anaerobic-aerobic, and the growth of preponderating of the phosphatic polyP bacteria of excess accumulation, makes active sludge phosphorus content higher than ordinary activated sludge.The alternate run of anaerobic stages and aerobic stage is conducive to the granulating of active sludge simultaneously, and sludge settling property is significantly improved, and improves contaminant removal efficiency.
Traditional nitrated-denitrification process of the general employing of bio-denitrification technology is oxidized to nitric nitrogen by ammonia nitrogen by nitrifier under aerobic condition, and then under anaerobic environment, denitrifying bacteria utilizes organism that nitrate-nitrogen reduction is become to nitrogen.The limitation of traditional technology is to need organism as the electron donor that completes nitrate reduction in denitrification process.The water inlet carbon-nitrogen ratio of China municipal sewage plant is generally lower, and the shortage of carbon source becomes the bottleneck that denitrogenation dephosphorizing efficiency cannot improve, and additional carbon can increase considerably sewage disposal expense.The discovery of anaerobic ammonia oxidizing bacteria makes sewage whole process autotrophic denitrification become possibility, and this bacterial classification has unique pathways metabolism, can utilize nitrite, as electron donor, ammonia nitrogen oxidation is generated to nitrogen.Compare traditional denitrification process Anammox technology and there is obvious advantage: 1. anaerobic ammonia oxidizing bacteria is chemoautotrophic bacteria, usings inorganic carbon as carbon source, thus in denitrification process without adding organic carbon source, save working cost; 2. nitrifying process only need be oxidizing to nitrite by 50% ammonia nitrogen, significantly reduces oxygen supply energy consumption; 3. the nitric efficiency of Anammox technology and removal load are higher, produce and seldom measure excess sludge; 4. can reduce in a large number the discharge of greenhouse gases Nitrous Oxide, environmental benefit is obvious.
As a kind of bio-denitrification technology of Sustainable development, anaerobic ammonia oxidation process has good prospect.But anaerobic ammonia oxidizing bacteria belongs to autotrophic bacteria, cell yield is low, is not easy enrichment at short notice.The anaerobic ammonia oxidizing bacteria doubling time of report is 11d at present, even longer.Simultaneous reactions device in the time of the initial stage mud easily run off, cause the smooth enrichment of anaerobic ammonia oxidizing bacteria more difficult.The present invention, for shortening the start time of anaerobic ammonia oxidation process, needs the mud of enhanced reactor to hold the ability of staying, to promote the fast enriching of anaerobism ammonia oxygen bacterium.Adopt novel technology of biological membrane to hold the ability of staying with enrichment by reinforcement sludge.Evidence can be shortened the start time of anaerobic ammonia oxidation process to a certain extent by add filler in system.
The research of Anammox technology at present mainly concentrates in the processing of high temperature high ammonia-nitrogen wastewater with application, and under normal temperature, the research of municipal effluent Anammox technology application is fewer.Synchronous denitrogen dephosphorus technology of city sewagte based on Anammox technology rarely has report.Applying of Anammox technical finesse municipal effluent needs the problem solving to comprise at present: how in reactor, effectively to hold and stay and enrichment anaerobic ammonia oxidizing bacteria; How thereby the mutual ratio of concerted reaction device different strain improves the stability of reaction operation; How to reduce the complexity of system running maintenance.Therefore, the novel apparatus and method of utilizing anaerobic ammonia oxidation process Treating Municipal Sewage need to be proposed.
