The sludge, a waste of brewery industries, was examined for potentials as a natural organic fertilizer (or soil conditioner) for lawn. Trial products were measured for changes of physical, chemical properties in laboratory and seed germination and seedling growth in green house were also tested. The results are as the following:1The sludge from distilled liquor brewery contained high quantity of organic matter which had proper physical and chemical properties for lawn fertilizer (natural organic fertilizer, soil conditioner, top-dressing mix) . It showed good characteristics in handling and capabilities to be developed as commercial products for golf courses. 2.Sludge from beer company needs proper treatment to improve physical properties for futher degradiation. It is because aggregation of the sludge particles prevented microbial activities and changing to soluble form. 3.Green carbon can be used as carbon source for organic fertilizer production using brewery sludge, but it should not contain wood extract which inhibit seed germination and seedling growth.

호기성 소화를 통해 안정화된 유기성 슬러지는 질소 비료로서 활용될 수 있는 잠재력이 있다. 본 연구에서는 식품공장 폐수 처리장에서 발생한 슬러지를 호기성 소화한 후, 소화액의 비효효과를 오이 생장을 통해 평가하였다. 공기 공급량을 200 mL/L/min까지 증가시킬 경우, 질산화와 비효효과가 향상됨을 확인하였다. 또한 일반 비료에 비해 슬러지 내 함유량이 부족한 칼륨 등을 보충하기 위해 음식물 쓰레기의 일종인 계란 껍질 가루를 시비 시 함께 투여하여, 식물 생장이 향상됨을 확인하였다. 본 논문에서 제시하는 적정 공기 공급량과 저가의 첨가제 투여는 슬러지 액비의 품질을 보장하는데 활용될 수 있을 것으로 사료된다.

The effects of sludge and fertilizer application on germination and seedling growth of woody plants on heavy metal mine tailings were evaluated by greenhouse experiment. Two different mine tailings (Lead-zinc mine tailings from Kwangmyong, Kyonggi-do and tungsten mine tailings from Sangdong. Kangwon-do). four fertilizer treatments (N +P +K: 20, 40, 60, and 80 kg/m$^3$), and four sewage sludge treatments (5.5, 11, 22.5, and 45 Mg/m$^3$) were used in the experiment. Tested plants were Pinus densiflora, Larix leptolepis, Amorpha fruticosa, and Alnus hirsuta. There were three replicates for each treatment. In addition, vermiculite was used instead of mine tailings to determine the effect of physical amendments. Fifty seeds of a species were sown in a pot (upper diameter 13.5 cm, depth 10 cm) and seedling emergence were recorded daily for 30 days. The highest germination rate was 53% for all treatments. Germination rate of Larix leptolepis was lowest among the four species studied. One month later after seeding, seedlings were thinned and only 5 seedling were left in each pot, and fertilizer and sewage sludge were applied once again. Growth of seedlings were determined for 10 weeks since then. Most plants grew very poorly or died within 5 weeks on lead/zinc mine tailings from Kwangmyong. The analysis of heavy metal contents by the total dissolution method showed that heavy metals generally increased in the order of tungsten mine tailings from Sangdong < sewage sludge from Puchon < lead/zinc mine tailings from Kwangmyong. Growth of woody plants was improved significantly by the fertilizer treatments on tungsten mine tailings. In contrast. survival and growth of woody plants were not affected significantly by the sewage sludge treatment on both tailings. This study shows that fertilizer applied to established seeded stands may provide some benefits in terms of increased ground cover in the field. It is suggested that reclamation should be proceeded by the study of the physico-chemical and biological characteristics of mine tailings.

하수슬러지를 알칼리(40 meq/L NaOH, 330 min. at 40$^{\circ}C$)로 가용화시킨 후 호기적으로 안정화시켜 생산한 액상의 비료(액비)로 오이, 배추, 국화 등의 농작물을 재배하여 비료로서의 활용가능성 및 그 안전성을 평가하였다. 위생적인 안전성을 확보하기 위해 검출한 분원성대장균은 연속공정보다 회분식 공정에서 더 높은 제거 효율을 보였는데 이는 아마도 긴 슬러지 체류시간(SRT) 때문이며 생산된 액비 모두 미국 EPA 기준의 B등급 이상이었다. 또한 우리나라에서 규제하는 비소, 카드뮴, 크롬, 수은, 구리, 납 등 6개의 중금속 중 크롬, 구리, 납은 대략 식물 건중량당 10 mg/kg 이하로 검출되었으나 비소, 카드뮴, 수은은 거의 검출되지 않았다. 그러나 규제 외 항목 중 선진외국에서 규제하는 아연과 니켈은 각각 최고 118 mg/kg과 15.7 mg/kg로 검출되었다. 아울러 생물량기준으로 볼 때, 활성슬러지액비(4.3 mg, dw)보다 소화슬러지액비(5.4 mg, dw)가 더 양호한 비효효과를 나타냈고 전처리한 액비(1.24 mg, dw)가 비전처리 액비(1.12 mg, dw)보다 더 좋았으나 액비 성분이 실제로 농가에서 사용하는 배양액 성분의 대략 60$\sim$80%를 차지했고 아연, 티타늄, 크롬 등의 중금속이 농축되었으므로 화훼 재배에는 무리가 없을 것이나 식용작물 재배 시에는 전적으로 액비에 의존하기 보다는 추가적인 비료로 사용하는 것이 타당할 것으로 사료된다.

Forage sorghum (Sorghum bicolor x S. bicolor) was cultivated for knowing the effect of alum sludge application on its root growth in a mountainous site, Kumsan. And the results obtained are as follows: The available P205 content in the soil seemed to decrease with the advance of level of alum sludge application. And plant P content decreased with the advance of sludge application without phosphate fertilizer. With phosphate fertilizer, root number of the forage was greater than that without the fertilizer. The root growth of forage sorghum was the highest with NPK and the least in control and alum application, and it is not recommended to apply NPK and alum together for the growth of the forage root. (Key words : Root, Sorghum, Mineral, Sludge, Kumsan)

An experiment of alum sludge application was carried out on a mountainous site, to know its effect on the growth of forage sorghum hybrid, Pioneer 93 1 (Sorghum bicolor x S. bicolor). When alum sludge with 80% water content was applied at the level of 133 ton per ha, the effect of the application on the growth of Pioneer 931 was much smaller than that of chemical fertilizer. But Eresh yield of the forage, with the sludge application, was greater than that without fertilizer when the soil is not fertile. But when the soil was comparatively fertile, the sludge application gave an adverse affect on the growth of the forage plant. The content of exchangeable K in the soil has a very close positive relation with the Eresh yield and plant height of the plant, while that of exchangeable Ca has a close negative relation with those growing factors. There was a tendency of yield decrease of the forage plant, when alum or compost was applied with NPK to the comparatively infertile soil especially for alum sludge. As a result, when soil is not fertile more attention will be necessary for applying alum sludge with chemical fertilizers. But to soil with better fertility, it is recommended to use alum sludge with chemical fertilizer to obtain more yield of the forage plant.

This study is conducted to provide useful fertilizer or soil conditioner of sludge from nightsoil treatment plant. Several possibilities present themselves. The major sink for disposal of waste sludge is the land, and in this case values will be measured primarily in terms of agricultural benefits. According to the result of sludge drying experiment, the drying rate with mixing once a day was more increased by three times than the state without mixing. And in sludge, N was 7-9%, P was 0.85-4.14%, and coliform groups in dried sludge were 75 MPN/gr.

This experiment was carried our in order to study effect of alum sludge compost of water treat-ment plant on the growth of Korean lawngrass (zoysia japonica Steud.) and on the change of soil chemical properties. Alum sludge compost was made out of chicken feces, sawdust and alum sludge. The results obtained are summarized as follows : 1. Alum sludge compost was appropriate for organic fertilizer of turfgrass management in golf course. 2.Application of alum sludge compost improved the chemical properties of soil such as pH, available phosphorous and exchangeable calcium. Also the growth of Korean lawngrass grown by the mixed application of alum and compost was more effective than that in single application of compost. 3.Chlorophyll content of Korean lawngrass had no differences in several treatments. 4. Alum promoted the uptake of potassium, calcium and the yield of dry weight hut the yield of dry weight was not affected by chemical fertilizer. 5.Alumimum toxicity was decreased by the mixed application of alum and compost but increased by single application of alum.
