preparation example Construction

[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...

Abstract

The invention belongs to the technical field of wastewater treatment and particularly relates to a recycling system for treating slaughter wastewater. The slaughter wastewater firstly enters a substrate area through a wastewater inlet, solid particles of the slaughter wastewater are filtered through internal substrate packing, and substances in the slaughter wastewater are pretreated and then the substrate packing is utilized as a fertilizer; the pretreated slaughter wastewater enters an ecological area through a stainless steel filter screen opening for advanced treatment; the slaughter wastewater subjected to advanced treatment enters a sunken stone area through a gate and is adsorbed by using sunken stone packing; entering wind enters a spray pope by using an exhaust fan through a wind distribution box and the sunken stone area is blasted with air and subjected to aerobic treatment; the treated slaughter wastewater is discharged through an outfall; and the sunken stone packing in the sunken stone area is used as a nutrient soil base material. The recycling system has a relatively good treatment effect on the slaughter wastewater and is high in treatment efficiency, and meanwhile, the nutrient substances in the slaughter wastewater can be fully utilized.

Description

technical field [0001] The invention belongs to the technical field of wastewater treatment, and in particular relates to a recycling system for treating slaughter wastewater. Background technique [0002] With the rapid development of the meat processing industry, the proportion of slaughtering and meat processing wastewater in industrial wastewater is increasing year by year. Slaughtering sewage comes from washing water before slaughtering, washing water for meat and viscera after slaughtering, and washing of slaughtering equipment and workshop floors. water. The sewage has the characteristics of large changes in water quality and quantity, large changes in slaughter volume and production wastewater with the seasons, high content of organic matter, good biodegradability, high content of suspended solids, and a large amount of blood waste, grease, hair, meat scraps, Visceral sundries, undigested food, feces and other wastes have a blood-red bloody smell, and some domestic ...
