Description
Technical field
The invention belongs to ground technical field of membrane, relate to specifically a kind of with mud be main material production can degradable, the high fertilizer efficiency mud liquid-state mulch film that is skeleton, preparation and using method thereof.
Background technology
Municipal sewage plant mud is the sedimentable matter such as organic matter, microbial bacteria micelle produced in sewage treatment process, and the residue such as the floating offscum of sewage surface, wherein containing a large amount of pathogenic bacterias, parasite, pathogenic bacterium and heavy metal etc.How further this mud is disposed in process, is the great difficult problem of world today's property field of Environment Protection.A small amount of mud is only had to be processed by the method for landfill, burning or compost utilization at present.Landfill then also exists large, large to the diafiltration liquid measure of the underground water source formation pollution problem of amount of landfill; Burn and then there is the problem that calorific value is low, air is produced to dioxin pollution; Fully utilize after compost, there is stench. percolate and outer permeation material and fertilizer efficiency is low and heavy metal pollution problem.
At China's national sludge yield in 2010 up to 2,850 ten thousand tons, wherein the mud of 80% processes, some air storages; What have abandons arbitrarily; What is more by mud with in water wash away, cause peri-urban rubbish Cheng Shan, mosquitos and flies evil is raw, causes secondary pollution and environmental safety hidden danger, serious threat human health, makes sewage disposal lose real significance; And further develop along with urbanization, the accumulation volume of mud can be increasing, promotes mud safe handling and dispose very urgent.
In addition, plastic film agriculture cultivation technology is progressively converted into " white pollution " by " White Revolution ", and then is converted into again " white disaster ".How solving " white pollution " to greatest extent, can promote agricultural produce again, is the new problem of pendulum in face of people.
Moreover the healthy of our people in " haze " serious harm.One of the arch-criminal forming " haze " is exactly the agriculture airborne dust of bare land particularly sandy land, and therefore how the solution agricultural airborne dust of low cost can make again to get agricultural profit, and is also problem demanding prompt solution.
Summary of the invention
The first object of the present invention be just to provide a kind of can utilize mud for main raw material prepare can be degradable and there is the liquid-state mulch film of mud for skeleton of high fertilizer efficiency;
The second object of the present invention is just to provide the method preparing above-mentioned a kind of liquid-state mulch film;
The third object of the present invention is just to provide the method using above-mentioned a kind of liquid-state mulch film.
The technical scheme realizing above-mentioned first object of the present invention is:
Mud is a liquid-state mulch film for skeleton, comprises the mud of 60 weight parts of water content 50-80%, the former powder of humic acid of 10-20 weight parts, the membrane-forming agent of 1.5-2.5 weight parts and the water of 15-25 weight parts.
In the above-mentioned a kind of liquid-state mulch film component of formation,
---the membrane-forming agent described in formation is that polyacrylamide and derivative thereof, sulfonated lignin are or/and derivatived cellulose is formed;
---the deodoring and disinfecting agent that the trichloroisocyanuric acid containing 0.01-0.10 weight part in described composition is formed;
---the inorganic salt of 2-5 weight parts containing formation linking agent in described composition.
The technical scheme realizing above-mentioned second object of the present invention is:
A kind of preparation method of liquid-state mulch film comprises:
Get mud to add the deodoring and disinfecting agent deodoring and disinfecting be made up of water-soluble trichloroisocyanuric acid and make above-mentioned mud reach agricultural hygienic standard; Then after adding the former powder of humic acid and water mix and blend homogeneous, then make by grinding, reaction the masterbatch that body of paste is formed;
Get polyacrylamide and derivative thereof, derivatived cellulose or/and sulfonated lignin combination formation has film forming, infiltration. dispersion. the sub-material of chelating and water retention property.
In addition, the inorganic salt forming linking agent can also be added in the preparation section of described masterbatch.
The technical scheme realizing above-mentioned 3rd object of the present invention is:
A kind of using method of liquid-state mulch film, comprise the dissolving of described son material 1.5-3.0 times of water to master batch weight part, added again in masterbatch to stir and made atherosclerotic body, and then added 1.0-2.0 times of water agitation and dilutions to atherosclerotic body weight part evenly, mulch film can be formed by atomizers spray.
A kind of mud provided by the present invention is that the liquid-state mulch film of skeleton compared with the existing technology has the following advantages:
One, sludge of sewage treatment plant is selected to be that degradable multifunctional liquid mulching film prepared by major ingredient, not only substantially solve a process difficult problem for mud, it is more importantly made to turn waste into wealth---mud contains the element of the nutrition such as a large amount of organic matters and N P and K, do with it production cost that liquid-state mulch film significantly can reduce liquid-state mulch film, be convenient to effective promotion and application; More due to of many uses, consumption is very big, the mud produced continually is had good home to return to, forms a great circulating economy chain, can culture fertility greatly, realizes the improvement of soil, saving water resource, promotion agricultural sustainable development;
They are two years old, use polyacrylamide and derivative thereof, the former powder of natural high moleculer eompound humic acids is raw material, because humic acids has the advantages that film-forming properties is strong, active gene is high, also have and improve soil physico-chemical characteristic, improve ground temperature, ventilation property. water-retentivity. promote effect of well developed root system, effectively can regulate soil acidity or alkalinity, solve soil compaction, strengthen plant cold resistance. drought resisting. the anti-adversity abilities such as disease and insect resistance; Polyacrylamide and derivative thereof are the long Chain polymkeric substance of polymer, and have film forming, flocculation, bonding and water absorbing properties, as soil improvement agent, water-holding agent is widely used in agricultural.
Its three, sulfonated lignin and derivatived cellulose are all natural high moleculer eompounds, and nontoxic odorless use safety, has film-forming properties, water-retentivity.Derivatived cellulose can make solid materials be evenly distributed, and sulfonated lignin can make powdery granule thing bond, very effective to control soil desertification.
