2. Mandatory inspection items and quality requirements of the central laboratory for harmless treatment and resource utilization of manure.
1. Odor monitoring, quality requirements are detailed in the following table for agricultural biogas slurry quality requirements;
2. Fecal sewage water quality testing: flow, chemical oxygen demand, ammonia nitrogen, total phosphorus, total nitrogen, suspended solids, five-day biochemical oxygen demand, fecal coliform bacteria, roundworm eggs, etc.;For quality requirements, please refer to the "Technical Guide for Self-monitoring of HJ Pollutant Discharging Units" for Livestock and Poultry Breeding Industry
3. Biogas slurry biogas fertilizer, the product of toilet manure resource utilization: pH, water insoluble, odor, total nutrients, organic matter, humic acid, fecal coliforms, total arsenic, total chromium, total cadmium, total lead, total mercury, total salt, etc.;
Based on the above testing items, a version of the list of supporting instruments and equipment of the central laboratory for the harmless treatment and resource utilization of manure that can meet the national standards has been sorted out, including odor detectors, manure detectors, multi-parameter water quality detectors, organic fertilizer moisture analyzers, microbial detectors, etc., as well as supporting auxiliary instruments and equipment such as centrifuges, as well as basic equipment test benches and office equipment.
Main rapid detection instrument: odor detector, odor detection.
Multi-parameter water quality detector to detect fecal wastewater and waste liquid.
Manure quality detector to detect organic matter, total nutrients, humic acid, heavy metals, etc.
Organic fertilizer moisture analyzer to detect dry density.
Organic fertilizer microbial detector to detect coliform bacteria.
Auxiliary instruments and equipment: acidity meter (to detect pH), ultrapure water machine (to provide distilled water), far-infrared enclosed electric furnace (to heat and dissolve samples), vacuum drying oven (to dry samples), water bath (to accelerate the dissolution of samples), sample shrinking machine (to homogenize samples), solid sample grinder (sample crushing), fertilizer sampler, reciprocating oscillator (to accelerate the dissolution of samples), electronic balance (to weigh samples), biological microscope (bacteria, fungi, microbial observation), vertical autoclave (sterilization), Test sieves (sieving samples), pipettes (dispensing operations), reagents, etc.
Basic equipment: computer (data recording, processing), printer (report printing, etc.), thermohygrometer (recording laboratory temperature and humidity), pharmacy cabinet (pharmacy storage), ultra-clean workbench (to provide a sterile environment), fume hood, refrigerator (refrigerated reagents), * workbench, work side table, etc.
