175 DEG C are risen to 10 DEG C/min speed in blanket of nitrogen, 1 h is dried, assigned temperature is continuously heating to, keeping temperature activates one section
Time, room temperature is cooled under nitrogen protection, obtain activating thermal decomposition product；
（3）By step（2）Obtained activation products grinding is sieving through 200-300 mesh sieves, is uniformly positioned over grounding electrode plate enterprising
Row low-temperature plasma is modified, and obtains zinc chloride activation sludge straw charcoal；
（4）Acrylic resin is heated to molten condition, natural ramie fiber, step is added（3）Gained zinc chloride activation sludge straw
Stalk charcoal and antioxidant 1010 are placed in progress melt-blown spinning in device for melt blowing with 300-500r/min speed high-speed stirred 1-2 hours
Silk, stands 6-8 hours at room temperature, discharging.
The step（1）Middle zinc chloride powder: the mass ratio of municipal sludge is 0.7: 1, wherein described municipal sludge contains
Water rate is 83%, and dewatered sludge volatilization is divided into 61%, and ash content is 39%.
The step（2）Middle nitrogen flow is 30L/h, and activation pyrolysis final temperature is 745-750 DEG C, keeping temperature activation
20min, wherein described maize straw and the mass ratio of municipal sludge are proportioning 1: 1.
The step（3）Middle low temperature plasma gas is oxygen, and battery lead plate spacing is 25cm, regulation power be 44W etc. from
The modified 10min of son.
The step（4）In in percentage by weight, described acrylic resin 50-55%, natural ramie fiber 25-
30%th, zinc chloride activation sludge straw charcoal 13-15%, antioxidant 1010 2-3%.
The step（4）Middle to control the area's temperature of device for melt blowing one be 160-165 DEG C, two area's temperature are 175-180 DEG C, 3rd area
Temperature is 190-200 DEG C, die head temperature is 200-215 DEG C, and drum rotation speed is that 90-95r/min carries out melt-spraying spinning.
The present invention has following beneficial effect：The present invention is using acrylic resin as matrix, and zinc chloride activation modified sewage sludge is to fill out
Material, is made, the present invention is effectively utilized discarded object sludge and straw, again with zinc chloride modified after being pyrolyzed through meltblown
Processing, the elevated oxygen level feature of wonderful utilization sludge and stalk forms CO, CO in pyrolysis2, the gas such as vapor, solid can be made
Hole is formed in powdered carbon, removes the complicated procedures of forming such as charing, the activation of conventional activated carbon preparation method from, cost is greatly reduced, simultaneously
Depolymerization, scission of link reaction occur for organic matter in sludge and maize straw, cause more carbon to be separated out in the form of volatile matter, and volatilize
The precipitation divided has pore-creating effect, has certain promotion to sludge straw charcoal Pore development；Finally use at low temperature plasma
The microstructure that reason not only changes sludge straw charcoal promotes the flowing between gas phase so that adsorbent hole substantially expands, and also leads to
Cross and be constantly be generated chemically reactive substance to change the surface property of charcoal, surface oxygen functional group quantity increase, so as to add
There is adsorption capacity, obtained non-woven cloth stronger adsorption filtration to act on, effectively purification automotive interior environment.
