Abstract
The invention relates to a special fertilizer for gum trees, which comprises sludge from an urban domestic sewage treatment plant, carbamide, monoammonium phosphate and potassium chloride, and all ingredients are fully mixed, granulated and packaged to prepare the special fertilizer. The special fertilizer is characterized by being prepared from the following raw materials based on percentages byweight: 50-70 percent of sludge from the urban domestic sewage treatment plant, 6-13 percent of carbamide, 10-16 percent of monoammonium phosphate and 12-24 percent of potassium chloride. The sludge as one of main materials from the urban domestic sewage treatment plate can not only solve the treating problem of sludge, but also replenish various nutrient elements in soils, and the special fertilizer improves the output of planted gum trees.
Description
Technical field
The present invention relates to recycling sludge utilization and fertilizer dedicated to eucalyptus production method, specifically is to utilize sludge from wastewater treatment plant to produce the method for fertilizer dedicated to eucalyptus.
Technical background
Minimizing, innoxious, stabilization and the recycling of research sludge of sewage treatment plant are one of problems of environmental science.The mud of Hainan Province city domestic sewage treatment plant contains the required nutritive element of a large amount of plant-growths, and meets " pollutent control criterion in the agricultural mud " agricultural requirement in (GB4284-84).The soil utilization of these mud is to solve one of effective ways of sludge treatment disposal.
Hainan Province's eucalyptus cultivated area has surpassed 60,000 hm
2, artificial eucalyptus woods growth is fast, the output height, and the various nutritive element consumption in the soil are fast, need in time to replenish.
Existing disclosed eucalyptus fertilizer only has several.As Du Yun good fortune disclosed " eucalyptus fertilizer production method " in 2007, fertilizer utilization organic matter, humic acid and enzymatic microorganism were fermented, and added nitrogen, available phosphorus, potassium again and mixed; Big, the Wu Cheng auspicious disclosed " a kind of Eucalptus fertilizer " of flood in 2006, fertilizer provide the special-purpose fertile of elements such as a kind of N, P, K, Mn, Mo, Zn, Cu, Fe, B; Calendar year 2001 Guangdong Prov. Inst. of Ecological Environment ﹠ Soil Science application " trace element fertilizer of control eucalyptus weeping disease " provides a kind of trace element fertilizer that can correct the crooked and weeping disease that the liquid bud is grown thickly of eucalyptus branch; But these all do not utilize sludge from wastewater treatment plant to make the basic raw material of fertilizer.According to the needs of eucalyptus growth to various nutritive elements, mud is used for the handling problems that fertilizer dedicated to eucalyptus production can solve mud, can replenish the various nutritive elements in the soil again, improve the output of eucalyptus plantation.
Summary of the invention
The purpose of this invention is to provide a kind of special-purpose fertile production method of utilizing sludge from wastewater treatment plant for the suitable eucalyptus plantation growth of basic raw material.The eucalyptus fertilizer that utilizes method of the present invention to produce can provide nutrition such as competent nitrogen, phosphorus, potassium to eucalyptus plantation, improves the organic matter of timbered soil, guarantees that eucalyptus grows fast.
The object of the present invention is achieved like this, it is made up of city domestic sewage treatment plant mud, urea, monoammonium phosphate, Repone K, with various composition thorough mixing, granulation, packing forms, and it is characterized in that: it is the fertilizer dedicated to eucalyptus that is prepared from following weight percentages:
City domestic sewage treatment plant mud 50%～70%,
Urea 6%～13%,
Monoammonium phosphate 10%～16%,
Repone K 12%～24%.
It is characterized in that: sludge generated in municipal domestic sewage is selected from Hainan Province city domestic sewage treatment plant mud, and mud is through compost maturity, and to make its water ratio be 10%～20%.
It is characterized in that: urea, monoammonium phosphate, Repone K are supplied by production firm.
It is characterized in that: various composition thorough mixing, granulation, making granularity is that the product of 1.00mm～4.75mm accounts for 70%.
It is characterized in that: nutrition such as competent nitrogen, phosphorus, potassium are provided for Hainan Province's eucalyptus plantation, improve the organic matter of timbered soil, guarantee that eucalyptus grows fast.
The mud eucalyptus fertilizer of Sheng Chaning as stated above, its leading indicator is: organic content 〉=20%, N+P
2O
5+ K
2O 〉=20%, moisture (free-water) 10%～20%, face shaping are granular.
Superior part of the present invention is: realize the sludge from wastewater treatment plant recycling, turn waste into wealth, eliminate secondary environmental pollution; According to the eucalyptus growth requirement of various nutritive substances is prepared, made the nutrition of fertilizer rationally balanced, be useful on the growth of eucalyptus.Owing to adopt municipal sewage sludge as one of main raw material, thereby can not only solve the handling problems of mud, can also produce new economic benefit, protected environment effectively.
