This "3 types" of domestic wastewater are treasures
In the fast-paced urban lifestyle, more and more people are starting to pay attention to sustainable ways of caring for green plants. In fact, the three types of domestic wastewater we produce every day can be turned into natural organic fertilizers through simple treatment, allowing potted plants to achieve breakthrough growth.
Expired Milk Fermentation Technique
High-Protein Nutrient Source
Dairy products rich in casein and whey protein can be converted into easily absorbable amino acids for plants through microbial decomposition. Every 100ml of expired milk contains 3.5g of high-quality protein, equivalent to the nitrogen content of professional liquid fertilizer.
Scientific Fermentation Process
Use a sealed jar with an air valve, mix milk and water in a 1:5 ratio. Adding citrus peel can neutralize the fermentation odor, and place it in a 25°C environment to ferment for 15 days. When the liquid turns amber and the pH value drops to 5.5, dilute it 50 times before use.
Rice Washing Water Conversion Method
Starch Energy Storage
This "3 types" of domestic wastewater are treasures
The first batch of rice washing water contains 80% of the B vitamins and soluble starch on the surface of rice, which can generate indole acetic acid that promotes root development through the action of yeast. Experiments show that the number of aerial roots of green vines treated with rice washing water increased by 47%.
Layered Fermentation Technique
Use a wide-mouth bottle for anaerobic fermentation, open the lid daily to release gas to avoid bottle explosion. Adding EM agents can shorten the fermentation period to 7 days. When the liquid produces fine bubbles and emits a wine fragrance, dilute it with a 1:20 ratio for watering.
Orange Peel Enzyme Production
Trace Element Treasure
Citrus peels are rich in limonene, apple peels contain polyphenols, and banana peels have a potassium content of 358mg/100g. Mixed fruit peel enzymes can supplement 16 types of trace elements, especially suitable for ornamental leaf plants.
Three-Dimensional Fermentation System
Chop the fruit peels to 1cm³ in size and mix them with brown sugar and water in a 3:1:10 ratio. Ferment using a light-proof ceramic pot, stir daily for the first 7 days to aid oxygenation, and then seal for anaerobic fermentation in the later stages. The mature enzyme has the best activity when the pH value is between 3.2-3.8.
Through systematic fermentation treatment, these three types of domestic wastewater can be converted into professional-grade organic nutrient solutions. Regular application can improve the soil aggregate structure, enhance plant resilience, and make indoor green plants grow爆发式. It is recommended for beginners to start with rice washing water, gradually mastering the secrets of home composting.
