Description of the invention (1) Background of the invention The annual amount of organic sludge in Taiwan is over 10,000 metric tons (after dehydration), and the moisture content is over 82%. Gel dehydration usually requires gel feathering and concentration steps. Therefore, PoiyAluminum Chloride or polymer gelling agent is added to promote cake formation and facilitate dehydration. However, after the sludge is agglomerated, it is not easy to disperse, which will cause limited oxygen transmission. If it is not pre-treated and directly mechanically stirred, the combined water content of the coagulant and gelling agent will increase with the stirring intensity, which will increase the viscosity of the sludge block and reduce the available water for microorganisms, so in the subsequent biological treatment At this time, the microbial activity is not easily improved. This is the bottleneck of industrial sludge high-speed fermentation and stabilization technology, so it is necessary to develop a pre-treatment technology to remove this bottleneck. SUMMARY OF THE INVENTION The object of the present invention is to provide a method for pretreating a biodegradable sludge block before composting, which enables the biodegradable components in the biodegradable sludge block to quickly and stably mature, which is beneficial to the compost fermentation in the subsequent stage Carry on. In order to achieve the above object, the present invention applies appropriate amounts of hydrogen peroxide and a surfactant to pretreat waste sludge blocks with high viscosity to effectively increase the dispersion and bulking of organic matter. It has been verified that the fermentation temperature of sludge compost can be rapidly increased, and the concentration of C02 produced by the same volume static reactor method has more than doubled, and the amount of organic matter removed has more than doubled, which can accelerate the sludge compost fermentation. In the pre-treatment method of the present invention, hydrogen peroxide is oxidized by the hydrogen peroxide enzyme in the microorganism to generate oxygen, which is passed the standard of pleasure by the action of the surfactant.

Description of the invention (2) Hydrogen oxide will easily penetrate the sludge block and help oxygen Formation of micro-bubbles. Surfactants can also release the water bound in the sludge block to increase the degree of sludge dispersion; meanwhile, surfactants can also emulsify organic components such as fat, protein and carbohydrates in sludge block in free water. It is good for microbial decomposition. Detailed description of the invention Printed by the Shell Standard Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs (please read the precautions on the back before filling out this page). Generally, the sludge maturation rate is affected by the physical conditions of the substrate, the carbon-nitrogen balance of the material, the aeration volume and Influence of ambient temperature. The sludge dispersion and free water are the prerequisites for biological treatment. Therefore, when composting sludge, bulky materials are usually added and mixed to promote the dispersion and aeration of sludge blocks. When the bulk material used is rice husk, bagasse, or pig manure, the average particle size of the material after mixing is about 2 cm or less. If a fibrous bulky material such as chemical sludge or waste paper waste from a paper mill is used, the mixed material will be bulky particles with a particle size of about 0.5 cm to about 20 cm. However, general industrial sludge must often be added with an appropriate conditioning agent before dehydration. Taking the sludge used in the present invention as an example, a coagulant aid such as polyaluminum chloride or a high-molecular gelling agent is added to promote cake formation, which is beneficial to the cake. Dehydration, which causes agglomeration and inability to fully disperse when the sludge mass is agitated and dispersed. The invention discloses a pretreatment method of a biodegradable sludge block before composting. The biodegradable sludge block is combined with 30-95% by weight of water. The pretreatment method includes the following steps: a) mechanically Disperse the sludge block to make it into dispersed sludge particles with an average flat diameter of 0.3-20 cm; and -4- the standard of this paper.

Description of the invention (3) b) At the same time when step a) is started, or before or after the start of the time, An aqueous solution containing hydrogen peroxide and a surfactant is uniformly sprayed on the sludge block; wherein 0.13-0.52 parts by weight of hydrogen peroxide and 0.05-3 parts by weight of the surfactant are used per 100 parts by weight of the sludge, and The surfactant has a molecular weight between 3 50-1 500 and a hydrophilic-lipophilic balance (HLB) 値 between 4-16 °. Preferably, it is used per 1,000 parts by weight of sludge in the pretreatment method of the present invention. 〇.2-0.3 parts by weight of hydrogen peroxide and 0.1-0.3 parts by weight Parts of the surfactant. Preferably, the HLB 値 of the surfactant in the pretreatment method of the present invention is between 12-16. Preferably, the surfactant is a non-ionic surfactant in the pretreatment method of the present invention. Preferably, the aqueous solution containing hydrogen peroxide and a surfactant is sprayed uniformly on the sludge block at the same time as the dispersion of step a) of the pretreatment method of the present invention or within 3-30 minutes thereafter, and the Spraying is completed within hours. The sludge block suitable for the pretreatment method of the present invention may contain multiple aluminum coagulant aid or polymer gelling agent, and the water content of the sludge block is preferably 60-90% by weight. The pretreatment method of the present invention further includes 5-40% by weight of the bulk material based on the weight of the sludge mass is added to the sludge mass of step a). Preferably, the pretreatment method of the present invention further comprises adding 3-20% by weight of decomposed middle compost based on the weight of the sludge mass to the sludge mass of step a).

Description of the invention (4) Preferably, step a) of the pretreatment method of the present invention is performed by a rotary stirring device at 1-50 rpm, preferably 10-20 rpm , The sludge block is dispersed at a speed. I believe that the technical principle of the present invention is that when H202 comes into contact with hydrogen peroxide enzymes in living organisms, the release of 〇2, 〇2 is retarded by the formation of microbubbles by the surfactant film, and is also delayed by the action of the surfactant. The soaking water easily penetrates into the sludge block, so the sludge block can be dispersed under a slow stirring action. In addition, the primary ecological oxygen has strong oxidizing power, which can increase the degree of hydrolysis of the sludge. In combination with the action of the surfactant, the biodegradable part dissolves more and is easy to be micro-biodegraded. In order to avoid excessive inhibition of microorganisms by 11202 and surfactants, the use amount must be properly controlled and mixed at a faster speed of 10-20 rpm without adversely affecting the compost fermentation in the later stage.
