Description
Technical Field
The utility model relates to a biological denitrification agent slow release device for sewage treatment, belonging to the technical field of sewage treatment equipment.
Background
The sewage containing nitrogen compounds is arbitrarily discharged without denitrification treatment, which causes harm to the environment and other industries, and mainly causes: (1) Eutrophication of slow-flowing water bodies, nitrogen compounds are plant nutrients, and the slow-flowing water bodies such as lakes and reservoirs are discharged, so that algae in the water can be abnormally proliferated. (2) In agricultural irrigation water, the content of T-N exceeds 1mg/L, and crops absorb excessive nitrogen, so that the phenomenon of green lodging can be generated. Therefore, the sewage containing nitrogen compounds should be subjected to denitrification treatment before being discharged or utilized.
According to the principle, the denitrification technology can be divided into two technologies of physicochemical denitrification and biological denitrification, and the physicochemical denitrification such as a stripping tower and the like is generally expensive, and the biological denitrification technology is widely applied due to the low-cost and high-efficiency performance of the physicochemical denitrification technology. The biological denitrification technology mainly refers to a denitrification technology, namely, a process that nitrogen nitrate and nitrogen nitrite are reduced into gaseous nitrogen under the action of denitrifying bacteria. Denitrifying bacteria belong to heterotrophic facultative anaerobic bacteria, and under anaerobic conditions, nitrite nitrogen and nitrate nitrogen are used as electron acceptors, and carbon sources are used as electron donors. There are two possible transformation pathways, namely: assimilation denitrification (synthesis) to finally form organic nitrogen compounds which become a component part of the thalli; the other is catabolic denitrification (decomposition), the end product being gaseous nitrogen. As an indispensable substance in the denitrification process, the kind of carbon source and the C/N ratio directly relate to the denitrification rate and denitrification effect. Typically 6-8 mg of COD is consumed per 1mg of N removed. However, the problem of insufficient carbon source always plagues the standard emission of ammonia nitrogen in the treated effluent of the current sewage plant in China, and the situation is more serious in low-temperature seasons. In order to ensure the smooth and efficient operation of denitrification, an additional carbon source is required to be added.
Conventional organic carbon source materials include low molecular alcohols such as methanol, ethanol, and the like. High molecular alcohols such as ethylene glycol or glycerol (glycerol). Molasses, glucose and the like can also be used as the carbon source. Other substances include starch, acetate, methane, natural gas and the like, but these substances have respective disadvantages as carbon sources, such as high cost, toxicity, uncertain addition amount, difficult transportation and the like, and the carbon sources have the problems that the adjustment of the supplementing amount is difficult to grasp, the initial excessive amount is insufficient in the later period and the like, so that the metabolism of microorganisms is influenced and the treatment effect is further influenced.
Based on the above reasons, the biological denitrification agent slow release device for sewage treatment is provided, and the technical problem to be solved is urgent.
