漿紙污泥與農林副資材為原料之醱酵機有機肥研製

本研究以漿、紙廠污泥及農林副資材(農業鳳梨果皮、竹屑、木屑)作適當配比混合之發酵試驗材料，其含水率為 50-60%，應用試驗型高速發酵機，調整適當溫度、時間、攪拌通風量，予以研製有機肥料。並測定其pH值、導電度、含水率、全磷、鉀、鈣、鎂元素含量、碳氮比、灰分及有機質含量等性質，其有機肥料之品質含量均大致符合行政院農業委員會規範之 5-11 雜項堆肥品目之法規標準。田間試驗結果顯示：漿、紙污泥與農林副資材混合之發酵有機肥料，有效使用量之施用可促進土壤肥力。在有機肥料之施用與土壤改良之對照組，兩者皆能增加小白菜之收穫產量。漿紙污泥為事業廢棄物，雖含有重金屬，但不至於對環境造成威脅，用於本試驗結果亦顯示適當漿紙污泥與農林副資材配比條件之下進行發酵，可成為有機肥料或土壤改良劑，為有效再利用的一種循環經濟處理方式。

In this study, the materials of fermentation, pulp paper sludge and agricultural sub-materials (pineapple peel, bamboo chips and wood chips) was used as an appropriate mix ratio, and its moisture content was conditioned at 50 – 60 %, and the experimental high-speed fermentation machine was applied to control the temperature, time, stirring ventilation, and to develop organic fertilizer. And its properties were measured pH, conductivity, water content, total phosphorus, potassium, calcium, magnesium content, C/N, ash and organic matter content. The quality of organic fertilizers generally meets the specifications of 5-11 Regulations and standards for miscellaneous compost items of the Council of Agriculture, Executive Yuan. The results of Field test shows that fertilizer can increase the soil fertilities by applying effective amount. In the conditions of applying organic fertilizer and the control of soil improvement, both can increase the yield of cabbage harvest. Pulp and paper sludge is industrial waste. Although it contains heavy metals, it does not pose a threat to the environment. The results of this experiment also show that the fermentation is carried out under the conditions of appropriate ratio of pulp and paper sludge and agricultural and forestry materials. Fertilizers or soil amendments are a circular economic treatment method for effective reuse.
