Often.
(3) leachate collection: opening diafiltration hydraulic control valve, and the surplus liquid that composting process generates is gone out by reactor bottom
Liquid mouth flows into the percolate collector below reactor.
(4) compost stench source emission reduction: compare foul gas under the different technical parameters such as C/N, moisture content and ventilatory capacity
Rule and dynamic change characterization are generated, the influencing mechanism that aerobic composting process different technical parameters discharge foul gas is specified,
So that it is determined that the optimised process operating parameter of the minimum release of foul gas.
(5) self-loopa of compost stench removes: closing cleaning of off-gas air outlet valve, opens foul gas circulating valve and effluvium
Pump, the gas generated using gas collection buffer collection composting process, after carrying out flow adjusting by foul gas flowmeter
It is passed through compost reactor from reactor bottom foul gas air inlet, is acted on using the biofiltration of heap body by odor destruction.
(6) foul gas is monitored on-line: during reactor is run, by sampling time or as needed of setting, opening gas
Sampling valve makes gas flow into gas chromatography-mass spectrometry or gas sensor, carries out on-line monitoring gas componant and concentration becomes
Change, data input computer is recorded and handled.
(7) biological sample collection and analysis: for analysis aerobic compost obnoxious gas in-situ control process heap body microorganism
Population structure, activity and quantity, taken at regular intervals compost sample.In general, in the material time point acquisition of compost reaction operation.
When sampling, stop air pump, open sample tap, carries out composting organisms sample, and using traditional microbiological method and advanced
Molecular biology method implement experimental analysis.
(8) composting process deodorizing effect regulates and controls: using experimental result early period as foundation, analyzing aerobic compost stench in-situ control
Correlation between effect and functional microorganism Population Dynamics illustrates obnoxious gas in-situ control microbiology mechanism, and
