Abstract
A long-acting organic composite fertilizer is prepared by adding zeolite into sludge from urban sewage as main ingredients, mixing, agitating, anaerobic treating, drying, sterilizing, adding into urea or ammocarbon proportionally, and balling to obtain final product. It's cheap and convenient, and has no secondary-pollution and more output.
Description
The present invention relates to a kind of long-acting compound organic fertilizer.Promptly be to adopt city domestic sewage or such as sugar refinery's waste water, beer brewery water, cotton pulp factory waste water, distillery waste water etc., the mud of handling the back generation through sewage work is main component, is equipped with the long-acting compound organic fertilizer that zeolite is made again.
China be one populous, the country of urban compact, there is 688 in large, medium and small city in the whole nation, more than 20,000 of organic towns, about 400,000,000 people of urban population, by the end of the year 2004, annual industry in the whole nation and urban life wastewater emission amount are 482 billion cubic meters, discharged volume of industrial waste water 222 billion cubic meters wherein, town domestic sewage quantity discharged 260 billion cubic meters.
Mud is the throw out that sewage work produces in sewage treatment process, accounts for 0.05～0.1% of sewage total amount usually, is example with the town domestic sewage, and 260 billion cubic meter sewage can produce 1.3 hundred million tons of-2.6 hundred million tons of mud.
Existing sewage work, generally the mode of employing stacking or landfill is handled the mud of generation.The secondary pollution problem that is caused by sludge of sewage treatment plants is on the rise, how the enormous amount that sewage work is produced every day, composition is complicated and with serious pollution mud to carry out harmless treatment and recycling be China and even the countries in the world government problem for paying close attention to deeply, if sludge of sewage treatment plants is not carried out harmless treatment, the sewage disposal that the input substantial contribution carries out is incomplete, even has lost meaning.The mud that sewage work produces has become big public hazards, cancellation mud is stacked field, landfill yard, can save a large amount of land resources, the secondary pollution of avoiding that mud is stacked, surrounding environment being caused in the landfill process, realize the harmless treatment of mud, the ultimate disposal of mud is strided forward to innoxious, resource utilization direction.
Containing ammonia nitrogen in the city domestic sewage is 35-60mg/L, colloidal solid shape ammonia nitrogen wherein and organism and ion state ammonium (NH
+ 4) most of flocculated and be deposited in the mud, by stable being stored in the zeolite after the zeolite adsorption, the nitrogen content that every Kg long-acting compound organic fertilizer obtains from mud can reach 4 * 10
5More than the mg, near the nitrogen content of urea.
The objective of the invention is to be to provide a kind of mud that utilizes city domestic sewage treatment plant to produce to be main component, produce long-acting compound organic fertilizer.
A further object of the present invention is to provide a kind of mud that city domestic sewage treatment plant is produced to carry out harmless treatment, the approach of recycling.
Another object of the present invention is to provide this long-acting compound organic fertilizer of a kind of production employed technology.
Long-acting compound organic fertilizer production technique of the present invention is achieved in that
1. add in mud through being heated to the phillipsite (or clinoptilolite) of high temperature dehydration after 100-120 ℃, the zeolite fineness is the 100-150 order, and add-on is every cubic metre of mud 5-10kg;
After the mud that 2. will add zeolite mixes with stirrer, enter squeezing machine again and remove clear water;
3. the anaerobic pond inner sealing more than 48 hours of inserting sealing of the mud after squeezing, aerobic microbiological and bacterium death are handled through hyperthermia drying and ozone sterilization again;
4. will dry at last and be long-acting compound organic fertilizer after thing adds suitable urea or carbon ammonium (to increase the not enough of nitrogen) balling-up.
Long-acting compound organic fertilizer of the present invention is a main raw material(s) with the mud that sewage work produces, and allocates zeolite, urea etc. again into, and proportioning is: mud (unit dry weight calculating): zeolite: urea=5: 4-4.8: 0.2-1
Sludge components of the present invention is as follows:

Zeolite is by silica (SiO
4) tetrahedron and alumina (AlO
4) tetrahedron is arranged in the skeleton with cage shape according to certain rules, have a lot of holes of uniform size and passage, the tool vesicular structure, its porosity reaches 23%-50%, specific surface area is big, surface energy height, the negative charge that powerful capacity that has by its surface and aluminum-oxygen tetrahedron have, so its adsorptive power is powerful especially, can absorb exchange selectively to ammonium ion.
The present invention utilizes this powerful adsorptive power of zeolite and to NH
4+Ion exchanging function, with zeolite after removing zeolite water under the 100-120 ℃ of temperature, fully mix with mud, make it fully adsorb organism and materials such as ammonia nitrogen, phosphorus in the mud, that adds that zeolite itself contains reaches own wt 3-5% potassium, as long as supply part ammonia nitrogen (urea or carbon ammonium), through anaerobism, aerobic treatment, drying, ozone sterilization and balling-up promptly obtain high-quality and efficient compoiste fertilizer.
Heavy metal content in the city domestic sewage is very low, zeolite originally fetters after Adsorption of Heavy Metal Ions and suppresses it and is difficult to discharge or shift, mud as fertilizer sources after handling like this uses, be safe not only to farm crop, but also because zeolite can absorb in the soil or the heavy metal that brings when using other fertilizer, so can also improve the quality of agricultural-food.
Advantage of the present invention and effect:
1, the invention solves a large amount of mud land occupation and the secondary pollution problem in treating processes that city domestic sewage treatment plant produces, the protection environment is had its meaning energetically.
2, containing ammonia nitrogen in the city domestic sewage is 35-60MG/L, colloidal solid shape ammonia nitrogen wherein and organism and ion state ammonium (NH
+ 4) most of flocculated and be deposited in the mud, by stable being stored in the zeolite after the zeolite adsorption, the content of every Kg long-acting compound organic fertilizer nitrogen can reach 40 * 10
4More than the mg, reach the nitrogen content of urea, mud itself is rich in phosphorus, potassium and a large amount of organism, zeolite contains the potassium of 3-5% again, long-acting compound organic fertilizer of the present invention, its fertilizer efficiency content and application effect have all surpassed the inorganic composite fertilizer that sell the existing market, meet or exceed national composite fertilizer standard.
3, used good ion exchangeable and the unique vesicular structure of zeolite tool of the present invention can promote the ion-exchange of soil, improves the ability of nutrients such as Soil conservation nitrogen, potassium and calcium, and improvement acid soil, salt affected soil are all had positive effect.Can from air, absorb water extremely effectively.In continuing brief rain period, the ability of the external moisture of this absorption is very favourable to plant growth, so can improve the geographic sand of arid and semi-arid.
4, zeolite used in the present invention can effectively keep the soil fertilizer efficiency, improves soil aggregate, improves agricultural product quality, and increasing crop yield can reach 10-30%.
