Description
Technical field
The present invention relates to a kind of nitrated ability fast repairing method of biological treatment of waste water system, belong to technical field of waste water processing.
Background technology
The treatment process of waste water mainly comprises the combined method of physical treatment process, method of chemical treatment, biological treatment and these treatment processs. Wherein, biological treatment is cheap with its processing costs, process effect well, does not produce the advantages such as secondary pollution and is widely used, and becomes the main stream approach of wastewater treatment both at home and abroad at present.
The bioremediation of waste water is the vital movement process by microorganism, is undertaken shifting and transforming by the pollutent (COD, ammonia nitrogen, total phosphorus etc.) in waste water, thus waste water is purified. Wherein, in the process of some high nitrogenous effluent treatment, the nitrated ability of biochemical system is most important to the removal of ammonia nitrogen in waste water. In the biological treatment system of waste water, playing nitrated ability, mainly nitrobacteria, this bacterium belongs to autotrophic type bacterium, taking the basicity in waste water as carbon source, is nitrate or nitrite by the mineralized nitrogen in waste water, thus realizes the removal of ammonia nitrogen in waste water. The nitrobacteria of degradation of ammonia nitrogen is compared with the broad spectrum of bacteria of degraded COD; the feature such as (dissolved oxygen, temperature, basicity, pH etc.), impact resistance low (toxicant, heavy metal etc.) that has that reproduction speed is slow, environmental compatibility is poor; result in the biological treatment system of waste water after being subject to extrinsic factor impact; nitrated ability often can be damaged, and causes system water outlet ammonia nitrogen to exceed standard.
After the nitrated ability of biological treatment of waste water system is destroyed, the measure usually taked at present stops water inlet, again seed sludge, vexed exposure system to allow system clear-cutting forestland. There is the problems such as draining exceeds standard in restore cycle length (usually need more than 15 days), Influence of production is big, reparation phase in the method.Therefore, the nitrated ability of biological treatment of waste water system is destroyed, and how to realize the quick reparation of nitrated ability, becomes the general character difficult problem that current waste water treatment plant faces.
