When adding chemical composition in above-mentioned steps, because of polyacrylonitrile fibre, Vltra tears in the composition of composition can replace filler effect, at this moment, the filled operation of (7) step can optionally be used or cancel.
Mud after above-mentioned combination treatment or garbage mixture, has good physical and chemical performance, can directly carry out (9) step machine-shaping, source according to rubbish or mud, and the chemical composition different components that adds, correspondingly make constructional ornamental materials such as brick, wall covering, ceiling material, sound-proof material.
Example one
This example is that example explanation utilizes chemical composition of the present invention to handle the method for mud or rubbish to handle domestic refuse, may further comprise the steps:
(1) step, separate: with the domestic refuse of collecting processings of classifying, the composition that will have higher direct utility value screens, as steel bar etc., directly recycling, other composition enters the subsequent processing processing.
(2) step, fragmentation: will separate in the remaining rubbish composition input refuse grinder and carry out fragmentation, and dehydration.
(3) step, microwave treatment: the rubbish after the fragmentation is delivered to carries out microwave degradation, virus killing, sterilising treatment in the microwave processing equipment shown in Figure 2 10.
(4) step, ultrasonication: utilize ultrasonic unit to produce ultrasonic irradiation rubbish or mud, make organic components wherein that strong oxidative degradation take place.
(5) step, system sand: the rubbish after will kill virus sterilization and the degraded is transported in the rubbish system sand machine makes sand, and composition and the mass percent by chemicals dosing plant adding chemical composition in system sand machine is simultaneously:
Polyacrylonitrile fibre 5%
Vltra tears 3%
Fluidizer 6%
Wherein polyacrylonitrile fibre and Vltra tears can effectively increase physicalies such as the intensity of the rubbish composition after the processing and hardness, and under the fluidizer acting in conjunction, it is hard fastening that compound particles becomes.
(6) step, slurrying: the garbage mixture of system behind the sand is transported in the rubbish pulper, adds suitable quantity of water, carries out slurrying, is 3% polyacrylamide by doser to wherein adding mass percent simultaneously, and paste mixture is flocculated.
