Investigation on Fertilizer Efficiency and Safety of Vegetable Waste Liquid under Different Storage Conditions
摘要
Abstract
To elucidate the effects of temperature,light,and oxygen availability on the fertilizer efficien-cy stability and application safety of vegetable waste liquid(VWL),an 90-day simulated storage experi-ment was conducted under eight differentiated storage conditions.Results of fertilizer efficiency moni-toring revealed that total nutrients(sum of total nitrogen,total phosphorus,and available potassium)and available potassium exhibited a pattern of"initial rapid increase followed by gradual decline"over time,while total nitrogen showed a sustained slow decrease.Total phosphorus accumulated rapidly during the early storage phase but subsequently displayed treatment-dependent divergence.Safety as-sessments indicated that aerobic conditions effectively inhibited the proliferation of Escherichia coli and significantly accelerated the mineralization of organic pollutants via aerobic metabolism,leading to a marked reduction in chemical oxygen demand(COD).However,concomitant ammonia nitrogen accu-mulation induced an alkaline pH shift.In conclusion,a single storage mode failed to harmonize these critical indicators.Consequently,an integrated regulation strategy comprising"aerobic pretreatment-anaerobic storage-bio-augmentation"was proposed.By optimizing environmental factors and inocula-ting composite microbial agents,this approach synergistically achieves COD abatement,pathogen inac-tivation,and pH homeostasis,facilitating the safe resource utilization of VWL.关键词
