总氮如何去除/总氮超标处理/总氮达标方法,本文讲述总氮的处理方法,其中传统的厌氧好氧方法局限较大,占地面积比较大,脱氮效率比较低,而且出水色素受到影响,通过湛清环保的高效脱氮设备HDN-1进行处理,能够把总氮彻底去除至排放要求。 Introduction: How to deal with total nitrogen / How to remove total nitrogen / Total over nitrogen treatment / Total nitrogen up to standard method The efficiency is relatively low, and the effluent pigment is affected. By processing with Zhanqing's environmentally-friendly high-efficiency denitrification device HDN-1 , the total nitrogen can be completely removed to the emission requirements.

I. Policy requirements for total nitrogen

Total nitrogen is defined as the total amount of various forms of inorganic and organic nitrogen in water.NO 2 -NH 4 +等无机氮和蛋白质、氨基酸和有机胺等有机氮,以每升水含氮毫克数计算。 Including inorganic nitrogen such as NO 3- , NO 2 - and NH 4 + and organic nitrogen such as proteins, amino acids and organic amines, calculated as milligrams of nitrogen per liter of water. It is often used to indicate the degree to which water bodies are contaminated with nutrients.

61号文件中要求,总氮总磷需要进行在线监测,氮磷排放重点行业的重点排污单位,应于2018630日前安装总氮、总磷排放自动在线监测设备并与环保部门联网。 According to the requirements of Document No. 61 of the Environmental and Environmental Affairs Office of the People's Republic of China, total nitrogen and total phosphorus need to be monitored online. Key pollutant discharge units in key nitrogen and phosphorus emission industries should install automatic online monitoring of total nitrogen and total phosphorus emissions by June 30 , 2018. Equipment and networking with environmental protection agencies. 复合肥)等肥料制造,合成氨等基础化学原料制造,淀粉及淀粉制品制造,屠宰及肉类加工,味精制造,乳制品制造,酒的制造,饮料制造,皮革和毛皮鞣制加工,染整精加工,纸浆制造和造纸,设有污水排放口的规模化畜禽养殖场,污水集中处理设施等。 Including the following industries: nitrogen fertilizer, compound fertilizer ( composite fertilizer ) and other fertilizer manufacturing, synthetic ammonia and other basic chemical raw materials manufacturing, starch and starch product manufacturing, slaughtering and meat processing, monosodium glutamate manufacturing, dairy product manufacturing, wine manufacturing, beverage manufacturing , Leather and fur tanning, dyeing and finishing, pulp manufacturing and papermaking, large-scale livestock and poultry farms with sewage outlets, centralized sewage treatment facilities, etc.

Second, the total nitrogen emission standards

要求为20mg/L ,一级A15mg/LAt present, it is required in the pollutant discharge standards of urban sewage treatment plants that the total nitrogen concentration discharge standard requires a level B of 20mg / L and a level A of 15mg / L. 总氮排放低于15mg/L ,一级A总氮排放低于10mg/LBeijing's comprehensive pollutant emission standards, total nitrogen emissions from level B are below 15mg / L , and total nitrogen emissions from level A are below 10mg / L. 表二要求总氮低于15mg/L ,表三要求总氮低于12mg/LDischarge standards for water pollutants in the textile dyeing and finishing industry Table 1 requires total nitrogen to be less than 20 mg / L, Table 2 requires total nitrogen to be less than 15 mg / L , and Table 3 requires total nitrogen to be less than 12 mg / L.

,相比于传统的生化池,总氮如何处理/总氮如何去除/总氮超标处理/总氮达标方法高效脱氮设备HDN-1具有占地面积小,脱氮效率高的特点。 Compared with traditional biochemical tanks, how to deal with total nitrogen / how to remove total nitrogen / overall nitrogen treatment / total nitrogen compliance method High-efficiency denitrogenation device HDN-1 Small area, high nitrogen removal efficiency.

:使用经过定制的表面处理的填料,比表面积大,使得生物膜的厚度大大增加,单位体积的微生物密度增加。 Professional custom packing, the specific surface area is greatly increased : the use of customized surface treatment of the filler, the specific surface area is large, so that the thickness of the biofilm is greatly increased, and the density of microorganisms per unit volume is increased.

:使用厌氧污菌种过三年的培养而成,通过在此过程中改变厌氧细菌的生存条件,使得筛选后的细菌能够耐酸碱,抗重金属,抗毒性并且耐低温以及耐水质波动,适应工业废水的特点。 Specially cultivated bacteria that are resistant to industrial wastewater water quality fluctuations : After three years of cultivation using anaerobic sewage bacteria, in the process of changing the living conditions of anaerobic bacteria, the screened bacteria can resist acid and alkali and resist heavy metals , Resistant to toxicity, low temperature and water quality fluctuations, adapt to the characteristics of industrial wastewater.

:设备内部流态经过特殊优化设计,建立了顺畅的排气微通道,促使生成的氮气快速从内部排出,减少反应器死区及无效空间,提高了反应器稳定性和脱氮效率。 Nitrogen removal technology to accelerate the denitrification forward : the internal flow pattern of the equipment is specially optimized and a smooth exhaust microchannel is established to promote the rapid discharge of the generated nitrogen from the inside, reducing the reactor dead zone and invalid space, and Reactor stability and nitrogen removal efficiency.

总氮如何去除/总氮超标处理/总氮达标方法具有脱氮效率高,占地面积小,易操作维护,污泥产量小,运行成本低等特点,被广泛应用于工业污水处理中,能够解决工业场地受限的困境。 Zhanqing environmental protection how to deal with total nitrogen / how to remove total nitrogen / overall nitrogen treatment / total nitrogen compliance method has the characteristics of high nitrogen removal efficiency, small footprint, easy operation and maintenance, small sludge production, and low operating costs. Widely used in industrial wastewater treatment, can solve the dilemma of limited industrial sites.

倍,快速脱除总氮。 High nitrogen removal efficiency- 20 times the efficiency of normal biochemical technology, and fast total nitrogen removal.

Small footprint-compared to traditional biochemicals, footprint is one-twentieth.

Easy to operate and maintain-fully automatic control, no need to change the packing, low backwash water volume and low frequency.

的总氮,吨水运行成本小于1/吨水。 Low operating cost-removing 20 mg / L of total nitrogen, the operating cost per ton of water is less than 1 yuan / ton of water.
