Description
Technical field
The present invention relates to fertilizer field more particularly to a kind of mash is given up as the system of raw material humic acid water-soluble fertilizer using cane molasses
Preparation Method and application.
Background technique
Guangxi and Yunnan are the main producing regions of China's sugarcane production, and sugarcane candy output accounts for 80% or more of national total output, system
Most of sugar by product cane molasses are used for fermenting and producing alcohol, and the waste liquid (hereinafter referred to as useless mash) of distilled spirit discharge is height
Concentration organic acidity waste liquid, color are mostly brown or brownish black, and waste liquid COD (COD) is 80~l20g/L, and biochemistry needs
Oxygen amount (BOD) 40~60g/L, pH are 4.0~6.0, and difficulty of governance is big.Once natural water is flowed into, it can be in a very short period of time
It causes aquatic animal dead, destroys the ecological balance of water body, cause soil and water environment degradation, or even jeopardize human health.
Useless mash belongs to high concentrated organic wastewater, the every production 1t alcohol in sugar refinery, about discharge 13~15t waste liquid.Yunnan molasses-spirit is every
6,500,000 t or more of oxygen consumption organic is discharged in 500,000 t or more of annual output.It is that now current sugar refinery handles useless mash that useless mash, which quantifies returning to the field,
Major way, and dosage is up to 7t/ mus, useless mash pours apply sugarcane after, it may appear that strong foul smell, while seriously affecting soil
Earth, water ecological setting.In addition our province sugarcane district Sugarcane Fertilization is mainly based on simple substance nitrogen, phosphorus and potassium fertilizer and compound fertilizer, and organic fertilizer is to filter
Based on mud, alcohol effluent, sugarcane leaf returning to the field and Animal manure.Fertilizer variety is single, applies urea, calcium superphosphate, potassium sulfate, chlorination partially
The fertilizer such as potassium, ammonium chloride, if things go on like this cause sugarcane district soil tilth to be deteriorated, and middle microelement deficiencies, chloride ion content seriously surpasses
Mark.
Summary of the invention
The purpose of the present invention is to solve the shortcomings of the prior art and providing one kind and giving up mash as raw material corruption using cane molasses
