Materials In this study, two widely used polymer materials were used, namely metallocene linear low density polyethylene (m-LLDPE, hereafter referred to as PE) and polypropylene homopolymer (PP), which were obtained from a commercial supplier (RESINEX).
Polymeric materials data, the melt flow index and the density from supplier, the melting temperature from DSC and molecular weight details from GPC.
The β-transition is the major transition in the polymer in general, which is when the materials are going through a glass/rubber transition.

The experiment use clinoptilolite powder as main materials to prepare the large specific surface and high porosity spherical compound filter material.Experimental results indicate that compound filter material is used as filter medium in biological aerated filter for wastewater treatment, in the early 5 days the average removal rate of NH3-N was 58.5% in biological aerated filter when the average influent NH3-N concentration was 37 mg/L.
Introduction As the biological aerated filter materials, Granular zeolite can improve the biological aerated filter against ammonia impact load effectively,because of material density, big water head loss, short backwash cycle from its irregular shape thus failing to popularize application.
Preparation of compound filter materials Natural clinoptilolite by activating 2 hours at 105-110℃ then cooling, into the ball mill grinding to zeolite powder, through 80 mesh sieve,adding pore-forming agent, adhesive by a certain proportion, after mixed evenly, spray water, rolling into a ball with the manual ball machine, form the size of 3-5mm spherical filter rules, removed into the constant temperature curing box, keeping the temperature of 25 ℃, relative humidity 99%, curing for 3-7 days, remove and rinse, drying to obtain the finished composite filter as shown in Fig. 1.
