立体弹性填料是接触氧化法工艺的核心部分，它直接影响着处理效果、充氧性能、基建投资、运行周期和费用。

生物接触氧化法是以附着在载体(俗称弹性填料)上的生物膜为主，净化有机废水的一种高效处理工艺。目前已广泛地应用于纺织印染、毛纺针织、啤酒食品、石油化工化肥废水、医疗及生活污水等处理，并获得了明显地环境效益、社会效益和经济效益。近年来，随着给水需量地增加，加上河水、湖泊水等地表水不同程度地受到大面积有机污染，采用接触氧化法工艺进行处理。多年来，该工艺因具有高效节能、占地面积小、耐冲击负荷、运行管理方便等独特优点而被设计部门广泛采用，深受用户的欢迎和青睐。
本生产推出的立体弹性填料和混合式立体弹性填料是我厂经各种条件和大量试验和长时间生产性运行结果表明为理想的载体填料。由于该填料独特的结构形式和优良的材质工艺选择，使其具有使用寿命长、充氧性能好、耗电小、启动挂膜快、脱膜更新容易、耐高负荷冲击，处理效果显著、运行管理简便、不堵塞、不结团和价格低廉等优点。该填料在不同的工艺水质条件应用时，可调节丝条粗细密度及不同的组装形式，完全适用各种废水的厌氧、兼氧、好氧等处理工艺。该填料属国内外首创，其结构、性能具有国际先进水平。

Stereo-elastic packing

Stereo-elastic packing is the core part of contact oxidation process, which directly affects the treatment effect, oxygenation performance, infrastructure investment, operation cycle and cost.

Biological contact oxidation (biofilm) is an efficient process to purify organic wastewater, which is mainly attached to the carrier (commonly known as elastic filler). At present, it has been widely used in textile printing and dyeing, wool knitting, beer and food, petrochemical chemical fertilizer wastewater, medical treatment and domestic sewage treatment, and has obtained obvious environmental, social and economic benefits. In recent years, as the demand for water supply has increased, and surface water such as river water and lake water has been subjected to large-area organic pollution to varying degrees, the contact oxidation process is adopted for treatment. Over the years, this process has been widely used by design departments due to its unique advantages such as high efficiency, energy saving, small floor area, shock resistance, convenient operation and management, and is welcomed and favored by users.

The stereo-elastic fillers and hybrid stereo-elastic fillers produced by our company are ideal carrier fillers after various conditions, lots of tests and long time productive operation. Due to its unique structural form and excellent material technology selection, the packing has the advantages of long service life, good oxygenation performance, low power consumption, fast starting and hanging film, easy replacement of film, high load resistance, remarkable treatment effect, simple operation and management, no clogging, no agglomeration and low price. The filler can be used in different water quality conditions by adjusting the thickness and density of silk strips and different assembly forms, and is fully suitable for the anaerobic, aerobic and aerobic treatment processes of various wastewater. The filler is the first of its kind at home and abroad, and its structure and performance have reached the international advanced level.
