Abstract
The invention discloses a kind of household-garbage processing process, including broken bag, disinfection treatment, screening, fermentation, sorting, the present invention disinfects house refuse, while avoiding and generating waste water,waste gas and industrial residue in garbage processing procedure, avoids secondary pollution.
Description
Technical field
The present invention relates to technical field of waste treatment, and in particular to a kind of household-garbage processing process.
Background technique
Domestic rubbish disposal is increasingly concerned by people, the method for garbage disposal, especially sharp by garbage classification and again
Method also occurs in succession, and steps into batch production ranks, at present common trash processing way mainly include the following types:
1, filling type is handled: using soils such as good farmland, mountain valley gully, useless holes, house refuse being filled and is buried.Although city in this way
House refuse be disposed off, but secondary pollution caused by rubbish is growing, and especially exhaust gas, waste water are easy broken
Bad atmosphere, polluted underground water, while causing the significant wastage of land resource.
2, it burns (power generation) method: rubbish being carried out to burn the processing for realizing garbage decrement, but it is generated after burning
Exhaust gas, waste water, waste residue etc. equally will cause secondary pollution, and remaining waste residue will also pass through secondary landfill, and this mode is put into greatly, and
Processing is not thorough.
3, revolving drum type screening machine: this is kind of a mechanization processor, rubbish can be carried out classification processing.It, which can be separated, slags tap
Soil and plastic paper, remainder will also carry out landfill disposal.This equipment work efficiency is low, and separation type is few, and there are also useless
Water, waste material cannot be handled, and equally will cause secondary pollution.
In addition, in existing waste disposal method, does not also carry out disinfection processing to rubbish, very big wound is caused to human body
Evil.
Summary of the invention
In order to overcome the shortage of prior art, the present invention provides a kind of household-garbage processing process, it is therefore an objective to house refuse
Carry out disinfection processing, while avoiding generating waste water,waste gas and industrial residue in garbage processing procedure, avoids secondary pollution.
Technical solution of the invention:
A kind of household-garbage processing process, it is characterised in that: including following processing step:
Step 1: broken bag, the house refuse being recovered are ground into small garbage through garbage pulverator；
Step 2: disinfecting, the house refuse investment disinfection tank that step 1 is obtained, and after the completion of investment, leads into disinfection tank
Entering temperature is 260 ~ 300 DEG C of steam, and control pressure is 17 ~ 20kg, and the retention time is 10 ~ 12min；
Step 3: the rubbish in step 2 by disinfection treatment is transported in rotary screen, is screened by screening；
Step 4: the rubbish after step 2 sterilizes is transported in fermentor and is passed through anaerobic bacteria and ferments by fermentation, it is desirable that
1 ton of rubbish matches 1 kilogram of anaerobic bacteria, and the humidity value for requirement of fermenting is 30% ~ 75%, and the pressure value of fermentation ends is 0.2mpa ~ 0.3
Mpa, when biogas concentration is 90% ~ 95%, temperature value is 70 DEG C ~ 80 DEG C；
Step 5: sorting, and the house refuse for completion of fermenting in step 2 is transported in mechanism for sorting, and sorted mechanism is sorted
It collects.
It is added pulverized limestone in preferred step 2 simultaneously, one ton of rubbish of weight ratio of pulverized limestone and rubbish is public with 1.3 ~ 1.5
Jin pulverized limestone.
The rotary screen used in preferred step 3 is three-level rotary screen.
Anaerobic bacteria in preferred step 4 includes the composition of following parts by weight, liquid bacillus megaterium 10% ~ 30%, liquid
Body blown-ball Azotobacter agent 10% ~ 30%, liquid colloid bacillus cereus agent 10% ~ 30%, liquid streptomyces microflavus agent 10% ~ 15%, liquid
Bacillus subtilis microbial inoculum 10% ~ 20%, liquid bacillus licheniformis agent 10% ~ 20%.
Beneficial effects of the present invention:
The present invention disinfects house refuse, while avoiding and generating waste water in garbage processing procedure, exhaust gas, giving up
Slag avoids secondary pollution.
