preparation example Construction

[0039]1. Preparation of activated sludge: Continuously inject air into domestic wastewater containing a large amount of organic matter (such as domestic wastewater in urban sewers), and form sludge-like flocs due to microbial reproduction after 1-15 days.

[0040] 2. Preparation of acidified cotton cloth: soak common commercially available cotton cloth with dilute hydrochloric acid for 1-24 hours to obtain the acidified cotton cloth.

Embodiment 1

[0042] Weigh each raw material according to the following weights: excrement (excrement in urban septic tank) 850kg, organic waste (discarded rotten vegetable leaves, rotten fruit, smelly fish and rotten shrimp, residual soup leftovers or aquatic plants such as water hyacinth) 50kg, Activated sludge 0.0001kg; crush the organic waste to a 40-mesh sieve and mix it evenly with the feces from which impurities have been removed to obtain a mixture; add activated sludge to the mixture, and carry out decomposition reaction under sealed conditions; the decomposition reaction is carried out under the following conditions : Decomposition reaction temperature: 28C °., decomposition reaction time: 14 days; every reaction is 4 hours and stirred for 10 minutes; after the decomposition reaction is completed, the solid and liquid in the reaction product are separated; the separated solid is irradiated with ultraviolet rays After sterilizing, use the biogas produced by the decomposition reactio...

Abstract

The present invention discloses a biological organic fertilizer and a preparation method thereof. The biological organic fertilizer is made of raw materials of the following weight portions: 85 to 95portions of dejecta, 5 to 15 portions of organic waste and 0.00003 to 0.00001 portion of activated sludge. The liquid fertilizer or the solid fertilizer contains various nutrients that are required for the growth of plants or crops (comprising macroelements and microelements). The liquid fertilizer is colorless, odorless and transparent; the removal rate of harmful materials reaches to 99.9 percent; and the removal rate of germina reaches to 86.5 percent. The liquid fertilizer can be used as a foliar fertilizer, a hydroponic fertilizer, a spraying fertilizer, a fertilizer that can be used through trickle irrigation, and a fertilizer that can be used through irrigation; the solid fertilizer can be used as a ground fertilizer and a dressing fertilizer. The fertilizer can be used convenientlyand is quite suitable for greening houses, cities or gardens. And the preparation method has the advantages of simple process, easy operation and low cost. Moreover, the preparation method is conducive to the pollution control and the environmental protection.

Description

technical field [0001] The present invention relates to an organic fertilizer, in particular to a high-efficiency bio-organic fertilizer prepared from feces and organic waste in septic tanks in urbanized excrement. The present invention also relates to a preparation method of the bio-organic fertilizer, The application thereof belongs to the field of fertilizers. Background technique [0002] In real life, the feces in the septic tanks in urban septic tanks are no longer a source of fertilizer for agriculture, but a source of pollution for lakes, rivers, and groundwater. Rotten vegetables and leaves, rotten fruits, rotten fish and shrimps, and aquatic plants such as water hyacinth and other wastes in the city are all regarded as water pollution. [0003] The invention patent application with publication number CN 1597633A discloses an organic fertilizer and its preparation method. The organic fertilizer is prepared from sludge, feces and aquatic plants. A certain amount of ...
