Abstract
The invention relates to a technology for preparing a green fertilizer by using residual sludge generated after a secondary biological treatment of high yield pulp papermaking wastewater, comprising the following steps of: (1) dehydrating the residual sludge generated after the secondary biological treatment of high yield pulp papermaking synthetic wastewater until the water content is not higher than 75%; (2) uniformly mixing the dehydrated sludge with crushed inorganic impurities of fast-growing wood or a straw raw material, granulating, and drying the above particles by coal-burning boiler's smoke as a heat source until the water content is lower than 15%; (3) uniformly spraying a bacillus subtilis liquid which accounts for 3-5wt% of the granulated fertilizer on the surface of the dried granulated fertilizer and removing the moisture in the bacteria liquid by the heat obtained from the granulated fertilizer drying process, so as to obtain the finished product fertilizer. The invention provides a method for preparing a green fertilizer by using residual sludge generated after a secondary biological treatment of high yield pulp papermaking wastewater. According to the method, the residual sludge generated after the secondary biological treatment of high yield pulp papermaking wastewater is uniformly mixed with crushed inorganic impurities of the fast-growing wood or the straw raw material; the mixture is granulated and then dried by the coal-burning boiler's smoke as a heat source until the water content is lower than 15%; the bacillus subtilis liquid which accounts for 3-5wt% of the granulated fertilizer is uniformly sprayed on the surface of the dried granulated fertilizer and the moisture in the bacteria liquid is removed by the heat obtained from the granulated fertilizer drying process so as to obtain the finished product fertilizer.
Description
Technical field
The present invention relates to a kind of paper waste and handle the excess sludge system greening after two stage biological is handled of excess sludge composting technology, especially high yield pulp paper waste with fertile method.
Background technology
Paper industry is the water rich and influential family, accounts for the 3rd of national industrial water withdrawal after coming thermoelectricity, weaving, and with regard to the pollution load total amount of draining, paper industry becomes one of the primary pollution source in waters greater than thermoelectricity and textile industry.Technological process of treating papermaking mainly is treated to the master with two stage biological.Produced a large amount of excess sludges in the wastewater treatment process inevitably.
The disposal of excess sludge is the thorny difficult problem in sewage work's operational process always.Excess sludge is the dispose of sewage inevitable outcome of process microbial growth of biological process, belongs to organism.But handle excess sludge so far and still be confined to methods such as landfill, burning.Landfill is limited by the place, can provide the soil of landfill fewer and feweri; Burning is lower because of sludge calorific value, needs extra fuel, and cost is higher; And composting receives the influence of heavy metal content and other factors in the mud, and use range is restricted, and its fertilizer efficiency is lower, relative cost is higher, has also influenced it and has applied.
Summary of the invention
The objective of the invention is to use the wastewater treatment excess sludge of high yield pulp papermaking to use fertile raw material for greening; With problems such as the disposal that solves excess sludge and saline and alkaline area greening soil moved in to improve the original source deficiencies is main purpose, in the composting process, adds an amount of useful microbe simultaneously and makes fertilizer have saline-alkali soil to afforest secondary alkali evil and prevent and treat the bio-feritlizer of function.
The objective of the invention is to realize through following technical scheme:
(1) the high yield cooking paper mill wastewater of conventional processed is carried out inorganic impurity mixing, granulation through pulverizing in excess sludge and fast growing wood or the stalk paper making raw material after two stage biological is handled;
(2) to be thermal source with the fire coal boiler fume to above-mentioned granulation fertilizer dry to water cut is lower than 15%;
(3) subtilis bacterium liquid evenly is sprayed at the granulated fertilizer surface of just having dried with the mass fraction of granulated fertilizer 3%-5%, the heat that the water utilization granulated fertilizer drying course in the bacterium liquid is obtained is able to remove.
Advantage of the present invention and positively effect are:
(1) the present invention's excess sludge of having utilized fast growing wood or cotton stalk high yield cooking paper waste to carry out after two stage biological is handled is the composting raw material with the inorganic impurity through pulverizing in fast growing wood or the stalk, has solved the outlet of secondary pollutant and inorganic impurity that paper making raw material is carried secretly.
(2) the present invention subtilis of adding is to the useful mikrobe of plant-growth and because the meta-bolites of this bacterial strain is acidic substance, thereby the secondary alkali evil of control saline-alkali soil greening is had certain control effect.Nontoxic, the safety of this bacterial strain.
(3) paper mill wastewater is belonging to organism through the excess sludge after the second-stage treatment, has the effect that increases the soil organism; Also contain the composition of the pollutent of not degrading fully in the significant proportion paper mill wastewater simultaneously in this mud, be the plant normal growth benefit materials like xylogen, silicon and various trace ingredients.
(4) the present invention disposes excess sludge with greening and combines with fertile, greening soil moved in to improve the original demand, and the fertilizer drying source is taken from flue gas and made fertilizer have the effect that the control saline-alkali soil is afforested secondary alkali evil with the useful microbe interpolation.
Embodiment
Below in conjunction with specific embodiment, the present invention is further specified.Following enforcement is illustrative, is not determinate, can not limit protection scope of the present invention with following embodiment.
Fertile method is used in the excess sludge system greening of a kind of high yield pulp paper waste after two stage biological is handled.The steps include:
(1) excess sludge that the high yield cooking paper mill wastewater is carried out after two stage biological is handled carries out processed, and its water cut is not higher than 75%;
(2) in dewatered sludge and fast growing wood or the stalk to be thermal source through the inorganic impurity mixing pulverized, granulation and with the fire coal boiler fume to above particle dry to water cut is lower than 15%.
(3) subtilis bacterium liquid evenly is sprayed at the granulated fertilizer surface of just having dried with the mass fraction of granulated fertilizer 3%-5%, the heat that the water utilization granulated fertilizer drying course in the bacterium liquid is obtained is able to remove, and obtains finished product fertilizer.
The principle of this step is: the excess sludge that fast growing wood or cotton stalk high yield cooking paper mill wastewater are handled through two stage biological is rich in somatic cells, is that organic substance is the secondary pollutant that wastewater treatment process main, that need disposal produces.But owing to fast growing wood or cotton stalk being the utilizability that paper making raw material and high yield cooking interpolation chemical cause has seldom increased this type of paper waste processing excess sludge.And remaining not lignin degrading and silicon and micro substance etc. all are natural nutrition to plant-growth in the mud, and beneficial microorganism adds the soil moved in to improve the original make fertilizer of the present invention can be used to afforest fertilizer or the greening of instead of part salt affected soil and has secondary alkali evil preventive and therapeutic effect concurrently in addition.
Claims (2)
