The core of school cafeteria kitchen waste treatment is
Compliance classification, Nissan daily clearance, qualification collection or on-site resourcing
, and strictly establish a ledger. The following is a complete and direct implementation plan:
First, regulations and management requirements (must be followed)
According to the Ministry of Education "School Food Safety and Nutrition and Health Management Regulations":
•
classified storage
: Set up a special container with a lid, with a clear logo.
Nissan daily clearance
。
•
Private processing is prohibited.
It is strictly forbidden to landfill, dump, or feed pigs by yourself
Qualified unit
collect and ship
/
处置。
•
ledger system
: record date, type, quantity, receiving and shipping unit, handover person,
retention
≥2year
。
•
Temporary storage specification
: Keep away from the food area, deodorant, leak-proof, fly-proof,
store
≤12hour
。
Second, the standard processing process (in-school link)
1.
Source classification (kitchen)
/
就餐区）
￮
food waste
: Leftovers, vegetable leaves, peels, meat bones, soup residues
￮
waste oil
: fried waste oil, swill oil
Special airtight bucket
(It is forbidden to pour into the sewer)
￮
Other garbage
Paper towels, disposable tableware, plastic bags
￮
recyclables
Plastic bottles, cartons, metal
Separate recycling
2.
Pretreatment (kitchen backstage)
￮
oil-water separation
: install
grease trap
/
全自动油水分离器(Like a golden ball
GBOS
系列），oil removal rate
≥95%
￮
solid-liquid separation
Drain water to reduce weight and leakage
￮
impurity sorting
Remove chopsticks, plastics, and metals to avoid damage to equipment
3.
closed temporary storage
￮
dedicated
Deodorant, with cover, pulley
Trash can,
Daily cleaning and disinfection
￮
Staging point:
Ventilation, hardening, anti-leakage, with flushing
4.
Qualified collection and transportation (mainstream plan)
￮
sign a contract
Municipal sanitation
/
持证餐厨处置公司
￮
promise
daily
/
隔日清运，
Closed car,
GPS
、联单
￮
Hand over and weigh, sign by both parties,
ledger archive
5.
Terminal disposal (factory)
￮
Resources:
Organic fertilizer, biodiesel, biogas power generation
￮
Harmless:
High temperature sterilization, landfill
/
焚烧
III. Comparison of three mainstream treatment options
1.集中收运（低成本、合规首选）
•
apply
: Daily output <
100kg
、当地有处置厂
•
process
: classification
oil-water separation
Barreling
Qualification collection and delivery
•
advantage
：
Low investment, compliance, worry-free
•
disadvantage
: Depends on receipt and transportation, has temporary storage odor, and has no income.
2.就地生物降解（校园推荐、日产日清）
•
equipment
: small
High temperature aerobic fermentation machine
(Like a golden ball
GBKW-S200
）
•
principle
：
60–70℃+
专用菌种，24小时减量 90%
•
product
：
Organic fertilizer
(Campus greening), waste oil recycling, wastewater discharge up to standard
•
advantage
：
No odor, small footprint (
3–5
㎡）、自动化、资源化
•
apply
Primary and secondary schools
/
高校食堂，daily processing
100–500kg
3.黑水虻生物转化（科研 / 职教特色）
•
principle
The larvae eat the garbage.
1kg
幼虫日处理 5kg 垃圾
•
product
：
Insect bodies (high protein feed)
+
虫粪（有机肥）
•
apply
: Agriculture
/
生物院校、可结合教学实践
IV. Key points for equipment selection (school cafeteria)
•
daily output
：
500人≈200–300kg /
天；
1000人≈400–600kg /
天
•
Oil-water separator (required)
￮
Small (
≤500People):
GBOS-M
，
1–3m³/h
￮
Medium (
500–1000
人）：GBOS-R，4–10m³/h
，
oil removal
≥95%
•
Integrated degrader
￮
Processing capacity:
200kg /
天、500kg / 天
￮
Occupation:
3–5
㎡Low power consumption

Key compliance and management elements
•
Waste oil is strictly prohibited from flowing out
: must pay
Qualified waste oil recovery unit
，
Sign contracts and build accounts
•
prohibit
“
gutter oil
”
reflux
：
full supervision, joint order, not sold to individuals

•
Environmental compliance
：
Sewage is not discharged directly, odor does not disturb people, and there is no breeding of mosquitoes and flies
•
Responsibility to people
: The person in charge of the cafeteria
first responsibility
Regular inspections, training, and assessments
6. Recommended plan (school cafeteria)
•
primary and secondary schools
/
小型食堂：
Oil-water separator
+
集中收运(Low cost compliance)
•
high school
/
中型食堂：
oil-water separation
+
就地生物降解机（
Resource-based, odor-free, daily clearance
）
