Moving Bed Biofilm Reactor (MBBR)

生态素MBBR是一种基于常规活性污泥工艺和生物膜介质的组合的高效生物处理过程。MBBR工艺利用吹气和缺氧罐内的浮动高容量微生物生物芯片介质。微生物消耗有机材料。介质为生物微生物提供增加的表面积,以连接和生长。增加的表面积减小了治疗废水所需的罐的占地面积。处理过程可以是有氧和/或厌氧的并且在大容量负载下操作。

MBBR如何工作

MBBR工艺利用曝气槽内浮动塑料载体(介质)以增加可用于治疗废水的微生物量。微生物消耗有机材料。介质为生物微生物提供增加的表面积,以连接到曝气池中的并生长。增加的表面积减小了治疗废水所需的罐的占地面积。通过从曝气槽的第一隔室底部添加氧气的气泡连续搅动介质。微生物消耗有机材料。与传统的二次治疗相比,它提供了卓越的效率和价值。

实际上,EcoloLix专门使用的MBBR媒体或生物芯片的活性表面积> 4000平方米/ M3,比当今市场上可用的任何竞争介质高达六(6)倍。
The MBBR is a complete mix, continuous flow through process which is based on the biofilms principle that combines the benefits of both the activated sludge process and conventional fixed film systems without their disadvantages.

身体特征

MBBR Biochip 30生物膜载体完全没有邻苯二甲酸酯或其他增塑剂,不含双酚A或任何其他芳族化合物。它由原始聚乙烯(无再循环PE),无机填料,甘氨酸酸的微量单酯(由椰子脂肪制成),柠檬酸和苏打水(Na 2 CO 3)制成。
The manufacturing process becomes extremely important when used with applications sensitive to additional harmful chemicals such as aquaculture. Bishpenol A and phthalates have bene known to cause cancer and have hormonal effects.
The parabolic shape of the BioChip 30 allows for a homogenous mixing of the Chips in the tank as well as for the active biofilm being optimally kept in the water flow. Hence, the supply of the microorganisms with substrate and oxygen is ensured at any time and at any load condition.

过程

移动床生物反应器(MBBR)工艺中的一个关键因素是废水组分与附着在载体(生物膜)上的微生物之间的充分而频繁的接触。反应器(反应罐)中载体元素的必要混合可通过使用好氧处理工艺所需的工艺空气供应来实现。在厌氧处理过程中,反应池中的载体可以通过泵送水或使用浸没的、缓慢旋转的混合器来适当移动。乐动-app直播
The characteristics and quality of the biofilm establishing on the carrier surface is not only influenced by shear forces in the tank but also by the composition and the loads of the pollutants in the wastewater (substrate). The more the wastewater is polluted with biodegradable pollutants, the more intense and the faster the growth of biomass.
Problems caused by a decrease in biodegradation efficiency are largely a consequence of an intense thickness of the biofilms, resulting in a reduction of the active carrier surface area. The MBBR BioChip 30 does not have this issue. Its process is very different in that the biofilms, which colonize the pores of the BioChip and which try to grow out of the pores, are kept constantly thin by shear forces. These shear forces evolve on the outsides of the carrier elements due to their movement in the water, and provide the self-cleaning effect of the MBBR BioChip 30. Consequently, the biofilms remain thin as they are protected from the shear forces only inside the pores. Thin biofilms are crucial for an optimal supply of the microorganisms with substrates (removable pollutants and nutrients) as well as with the oxygen required for the aerobic biodegradation processes. In this way, the MBBR BioChip 30 allows for constantly high biological removal rates and reliable process stability.

MBBR Biochip 30提供了任何可比载体介质的最稳定和可靠的过程。为了说明这一点,我们在anAmmox过程中显示了它的使用情况。这是在废水和污水的生物处理过程中发生的过程,氮氮(NH 4 +)和亚硝酸盐(NO 2-)在缺氧条件下对分子氮进行对称。
生物膜载体的表面特征must ensure the permanent attached growth of the bacteria. In other words, the biofilm carrier has to provide a porous and micro-rough surface structure which enables the planctomycetes (bacteria) to permanently attach to the carrier surface. Utilizing the MBBR BioChip 30 carrier media planctomycetes can permanently settle in the protected pore structure of thie carrier and are, as a result, prevented from being flushed out of the reaction system.
MBBR Biochip 30通过允许细菌在可以繁殖的芯片的保护区域中沉淀来提供高空时间率。这也确保基材可以通过扩散转移到更深的生物膜层中。由于材料厚度约为。1.1毫米的载体介质,扩散深度约为。不超过载体两侧0.5毫米。这完全满足了具有深度约为大约的特殊孔系统形式的最佳栖息地的要求。分别在MBBR生物芯片30上或在MBBR生物芯片30中0.5mm。

典型的anammox应用程序

市政或国内污水处理厂用来自污泥处理过程的高铵氮负荷(NH4-N)进行操作。这种部分流程通常重新供应到生物主流过程,其中由于一方面的工艺空气流动而导致能量消耗,并且另一方面的BOD消耗(去硝化过程所需的碳源)。然而,在最佳条件下,可以通过厌氧过程治疗该滤液流动,从而可以在大力和液压方面减轻治疗厂。

Cost Savings

MBBR生物芯片30提供比许多其他载体类型更有利的价格-表面积比。为了正确评估载体介质的报价,您需要比较不同介质的价格,而不是每立方米,而是每平方米,因为每种介质的m2/m3比率不同。要进行准确的成本比较,需要的是受保护的活性表面积(单位:2/m3),而不仅仅是载体介质的体积(单位:m3)。

节能

The special shape and specific gravity of the colonized MBBR BioChip 30 provide unique motion characteristics which require less agitation energy in the form of process air supply in order to keep the carrier suspended in the wastewater. By using the MBBR BioChip 30 Wastewater treatment operators will benefit from significant savings in operational expenditure.

长寿/穿着

与其尺寸相比,每个MBBR Biochip 30介质具有非常低的质量。因此,当用另一种载体元素进行接触时传递的脉冲是微不足道的,因此大幅减少磨损和磨损。其他管状载体类型(通常注射成型和与其大小的重量)相反地在运行中留在废水处理厂的澄清器中的水面上的一定时间之后破裂。
