The invention discloses a method for produce liquid organic fertilizer with starch wastewater to improve saline and alkaline land. Through the strainer filtration, anaerobic biological filter fermentation, solar aeration biological filter fermentation, starch phosphate and PPFC hydrolysis, microbial fermentation agent fermentation and other deep treatments, the starch wastewater can become liquid microbial fertilizer containing rich beneficial microbial flora and many kinds of secondary metabolites. After the application of such fertilizer, the reduction of microbial population in improved secondary saline-alkali land can be alleviated, which may increase the productivity by 20%-30%; therefore, cost can be saved and soil depletion, hardening and salinization can be alleviated with the trend of energy saving, environmental protection and sustainable development is satisfied.
Description
Technical field
The present invention relates to technical field of fertilizer, specially utilize starch wastewater to produce organic for improveing the liquid in salt-soda soil
The method of fertilizer.
Background technology
Wheaten starch and corn starch extensively use in commercial production and daily life, but can produce in its production process
Raw substantial amounts of waste water, containing organic components such as a certain amount of starch, pentosan, protein in waste water, direct discharge can cause sternly
The environmental pollution of weight.At present the processing method of starch wastewater all uses the processing method of sanitary sewage, i.e. activated sludge process,
Can discharge after COD is up to standard.The research of utilization of starch wastewater is a lot, as utilized starch wastewater to produce biogas, due to natural pond
Liquid cannot effectively utilize and process, and the processing method of this maturation is the most gradually abandoned.Starch wastewater is also utilized to produce micro-
Biological flocculant, single cell protein, pulullan polysaccharide, microbial insecticide etc., because complex process, the reasons such as product cost is high
Also cannot implement.
Saline-alkali soil is salinization or a class soil of alkalization formation, including solonchak, alkaline earth and various salinized soil.In arid
And the salinity contained by semiarid zone, underearth and subsoil water, due to evaporation from land effect, along with soil capillarity makes
The surface layer that is raised to waterborne of contained salinity, after moisture evaporation, makes salinity stay upper soll layer, builds up and form salt-soda soil.Strand
Stain is invaded due to resident sea water in area, and salt-soda soil is distributed more widely, and salt content is high, gathers too much solvable in upper soll layer or the soil body
Property salt.Salt-soda soil surface soil is dried more, white, even forms salt incrustation, be full of cracks of hardening, and salinity is high, and corrosivity is strong,
Can destroy plant cell tissue, hinder plant growing, high salt basicity soil even can directly make root system of plant rot to cause plant
Dead.More seriously the microbial population of secondary salinization of land soil reduces.Soil microorganism and soil fertility have and
Close relationship, higher microbial activity is the important symbol of fertile soil.Therefore, soil microorganism is fertile at soil and soil
Power is formed and plays an important role in evolution.Secondary salinization of land increases the weight of along with saline and alkaline degree, the work of soil microorganism
Property substantially reduces, and population quantity drastically reduces.Particularly aerobic microbiological, owing to air capacity reduces, oxygen is not enough, and quantity is obvious
Decline.
If starch wastewater being carried out advanced treating, not only can solve problem of environmental pollution, and can turn waste into wealth,
Improve the crop yield in salt-soda soil.
Summary of the invention
