[0028] Preparation of matrix filler: take rice straw and put it into a pulverizer for crushing, pass the crushed material through a 50-mesh sieve, collect the sieved particles, put the sieved particles into a press, and squeeze them at 20MPa for 10-15 minutes, then squeeze Put the compressed material into a tubular carbonization furnace, set the temperature at 400-430°C, carbonize for 3-5 hours, and collect the carbonized material; according to the mass ratio of 8:3:2-8:5:2, take the above-mentioned carbonized material, rapeseed cake and The wheat straw is put into a straw grinder for crushing, passed through a 30-mesh sieve, and the sieved matter is collected to obtain the matrix filler.
[0029] Preparation of sunken stone filler: According to the mass ratio of 4:3:1, take vermiculite, river pebble and feldspar and put them into a pulverizer for crushing, pass through a 30-mesh sieve, and collect the sieved particles to obtain sunken stone filler.
[0030] Such as figure 1 ...
example 1
[0032] The invention constructs an ecological zone, prepares a matrix filler and a sinking stone filler, and the slaughter wastewater is treated through the substrate zone 1, the ecological zone 2 and the sinking stone zone 3 in sequence.
[0033] The process of the present invention is as figure 1A recycling system for treating slaughter wastewater is shown, which is composed of matrix area 1, ecological area 2 and sinking stone area 3. After the slaughter wastewater enters the matrix area through the wastewater inlet 4 on the upper part of the matrix area 1, it passes through the matrix area 1. The inner matrix filler 5 filters the solid particles of the slaughter wastewater and pretreats the substances in the slaughter wastewater. After the pretreatment of the slaughter wastewater is completed, the matrix filler 5 is used as a fertilizer, and the pretreated slaughter wastewater passes through The stainless steel filter screen port 6 at the bottom of the matrix area 1 enters...
