Abstract
This invention provides a method for manufacturing organic and organic-inorganic composite fertilizers using wastewater from sodium hydroxide-sodium sulfite paper production. The method comprises: (1) extracting the wastewater; (2) condensing the wastewater; (3) manufacturing lignin powder; (4) manufacturing organic and organic-inorganic composite fertilizers. The method can make good use of wastewater from paper production, protect environment and save resources. The produced organic and organi-inorganic composite fertilizers have such advantages as abundant nutrition (organic matters as well as N, P, K and trace elements), high bioactivity and long effective time, and can improve crop quality.
Description
Technical field
The present invention relates to a kind of preparation method of organic, mixed organic manure, relate in particular to a kind of papermaking black liquor through alkaline process including process of sodium sulfite that utilizes and prepare method organic, mixed organic manure.
Background technology
China has the thousands of families in middle-size and small-size paper mill now, be raw material with the herbaceous plant mostly, discharge a large amount of cooking waste liquors every day, the common name black liquid of straw pulp paper-making, contained pollutent has accounted for more than 90% of full factory disposal of pollutants total amount in the black liquor, and it is that China's water pollutes one of maximum source of pollution.Contain Mierocrystalline cellulose, xylogen and hemicellulose three big compositions in the herbaceous plant raw material, papermaking mainly utilizes Mierocrystalline cellulose, pulping by cooking has extracted Mierocrystalline cellulose, and xylogen and hemicellulose (solid substance that is called black liquor) are entered in the black liquor with the caustic soda, the S-WAT that add and be abandoned, promptly get one and abandon two, with regard to quantity, with the wheat straw is example, Mierocrystalline cellulose only accounts for 40%, xylogen accounts for 25%, hemicellulose (glycan class) accounts for 28%, and promptly the paper mill has only utilized 40% of raw material, and has abandoned 60%.Hence one can see that, and the paper mill quantity of pollutant discharge is very big, and main component wherein is utilizable resource.
China's paper-making pollution improvement technology can be summarized as two big classes at present: alkali recovery technology, materialization add biochemical technology.Alkali recovery technology is subjected to that investment is big, working cost is high and restriction such as industrial scale, can't be adopted by papermaking straw pulp factory; Materialization adds biochemical technology investment and many, and floor space is very big, the working cost height, and the Pollution abatement effect is bad and without any economic benefit.
Summary of the invention
The purpose of this invention is to provide a kind of papermaking black liquor through alkaline process including process of sodium sulfite that utilizes and prepare method organic, mixed organic manure.Adopt papermaking black liquor through alkaline process including process of sodium sulfite of the present invention to prepare organic, mixed organic manure, the extraction rate reached of black liquid is more than 90%, solid substance in the black liquor is all changed into product, when administering the black liquid pollution, make full use of also that available resource prepares organic, mixed organic manure in the papermaking black liquor through alkaline process including process of sodium sulfite, produce good economic benefits, overcome the problem profit that exists in the present improvement papermaking black liquor through alkaline process including process of sodium sulfite pollution.
The present invention utilizes papermaking black liquor through alkaline process including process of sodium sulfite to prepare method organic, mixed organic manure, and its step is as follows:
