空气中颗粒物去除技术主要有机械过滤、吸附、静电除尘、负离子和等离子体法及静电驻极过滤等。
Particulate removal technology in the air mainly includes mechanical filtration, adsorption, electrostatic precipitation, anion and plasma method and electrostatic electret filtration.
机械过滤一般主要通过以下3种方式捕获微粒：直接拦截，惯性碰撞，布朗扩散机理，其对细小颗粒物收集效果好但风阻大，为了获得高的净化效率，滤芯需要致密并定期更换。
Mechanical filtration is generally used to capture particles in the following 3 ways: direct interception, inertia collision, and Brown diffusion mechanism, which have good collection effect on fine particles but large wind resistance. In order to obtain high purification efficiency, the filter core needs to be compact and replaced regularly.
吸附是利用材料的大表面积及多　钢纤维混凝土具有与普通混凝土一样的搅拌、运转和施工性能,纤维在混凝土中不会结球,分布均匀,可在商品混凝土搅拌站进行生产并能用于泵送施工。铣削钢纤维混凝土的早期坍落度损失较大,30分钟损失32%,2小时损失42%。钢纤维混凝土的实际工作性优于相同的坍落度的普通混凝土。钢纤维混凝土具有良好的材料性能,与普通混凝土相比,其抗压强度提高2～20%；弯拉强度提高20～50%；劈裂抗拉强度提高20～40%；耐磨性能提高40%左右,其物理力理性能****可以满足城市道路工程及检查井盖等配套构件需求技术指标。钢纤维粗糙而洁净的表面,能与混凝土中的水泥浆体牢固的结合,这是铣削钢纤维提高混凝土各种性能的根本原因。孔结构捕获颗粒污染物，很容易堵塞，用于气体污染物去除效果更显著；
Adsorption is the use of materials with large surface area and porous structure to capture particulate pollutants, it is easy to plug, for gas pollutants removal effect is more significant;
静电除尘是利用高压静电场使气体电离从而使尘粒带电吸附到电极上的收尘方法，其风阻虽小但对较大颗粒和纤维捕集效果差，会引起放电，且清洗麻烦费时，易产生臭氧，形成二次污染。
Electrostatic precipitator (ESP) is a method of collecting dust on the electrode by ionization of high voltage electrostatic field so that the dust particles are charged to the electrode. Although the wind resistance is small but the effect is poor on the larger particles and fiber, it will cause the discharge, and it is easy to produce ozone and form two times of pollution when cleaning trouble and wasting time
