With intervals of every 11 days, 4 times of semi-successional addition of green grasses and pig manure (9:1) to the fermentor as the fermenting materials for methane production were applied. After each addition of new materials, the growth curves of principal microbial physiological groups were in a similar tendency. In the later additions, the highest numbers of cellulose decomposing bacteria acid-producing bacteria and ammonifying bacteria gredually decreased, but the methane producing bacteria remained constant....

With intervals of every 11 days, 4 times of semi-successional addition of green grasses and pig manure (9:1) to the fermentor as the fermenting materials for methane production were applied. After each addition of new materials, the growth curves of principal microbial physiological groups were in a similar tendency. In the later additions, the highest numbers of cellulose decomposing bacteria acid-producing bacteria and ammonifying bacteria gredually decreased, but the methane producing bacteria remained constant. In this semi-successional fermentation, a prolonged period of high rate daily gas production was maintained. The daily gas production rate was in positive relationship with cellulose and hemicellulose decomposition rates, which were directly in relation to the development of cellulose decomposing bacteria. Methane content of the gas produced and the methane producing rate were determined by the total number of methane producing bacteria developed. The methane production after each addition of fermenting material was in constant rate.

每隔11天以青草和猪粪(9:1)连续补料四次,每次补料后主要微生物生理群的消长趋势基本一致。随着补料次数的增加,纤维分解细菌、产酸细菌、氨化细菌的最高菌数略有下降趋势,其菌数对数由第一次补料后的5.3、8.6、7.7到第四次补料后则为4.6、6.28、6.28。而产甲烷细菌则比较稳定,甚菌数对数均为6.0。半连续补料能维持较长时间的较高日产气效率。日产气效率和纤维素、半纤维素降解率呈正相关,而纤维素、半纤维素的降解率又直接受纤维分解细菌的影响。每次补料后,纤维素降解率分别为38.51%、38.80%36.71%和31.96%,平均日产气效率分别为17.90、19.90、18.50和17.80m1/g·d。沼气中甲烷百分含量和日产甲炕效率的高低与产甲炕细菌菌数有关。每次补料后的平均甲烷百分含量为58.00%、52.30%、55.80%、60.00%,平均日产甲烷效率分别为10.97、10.54、10.88、10.68ml/g·d,比较稳定。

City gas supply by coke ovens, vertical retorts, water-gas generators and two stage water-gas generators are presented. Investment comparison of coke ovens and water-gas generators shows that water-gas should be favored in small and medium cities. To save investment, surplus gas from existing factories should be utilized in the first place. In samll cities direct conversion of water-gas avoiding methanation is to be perferred, i. e. supply of gas with lower heating value is reasonable and more economic for a...

City gas supply by coke ovens, vertical retorts, water-gas generators and two stage water-gas generators are presented.

In samll cities direct conversion of water-gas avoiding methanation is to be perferred, i. e. supply of gas with lower heating value is reasonable and more economic for a daily gas supply exceeding 100000m3, methanation may be more suitacle.

城市煤气气源有焦炉、直立炉、水煤气炉、两段水煤气炉等,文中列出了焦炉与水煤气炉的投资比较,说明水煤气是中小城市的主要气源。为节约投资,首先应利用工厂余气,对于规模较小的城市仅需进行变换,而不需进行甲烷化,即供应发热值较低的煤气经济上是合理的。而日供气规模在10×10~4m~3以上时,则采用甲烷化方案也是合适的。

The municipal organic refuse was treated using direct anaerobic dry fermentation and aerobic first anaerobic next fermentation. The relation between the number change of volatile acids in the process of fermentation was studied using the dilution method, corresponding culture medium, and the Most-Probable-Number method. The results attained are as follows:In the process of the direct anaerobic fermentation, the highest concentration of volatile acids is 35765 PPM, the average gas yield 25.15 ml, the number of general anaerobic heterotrophic bacteria, protein ammonifying bacteria, hydrogenproducing acidoge-nic bacteria are higher than that in the aerobic first and anaerobic next fermentation, that of methanogenic bacteria is 210 times lower than that in the aerobic first and anaerobic next fermentation.In the process of aerobic first and anaerobic fermentation next, the highest concentration of volatile acids is 9180 PPM in the end of aerobic stage, acetic acid and b(?)tyric acid of the volatile acids decreased gradually in the anaerobic stage, but propionic acid increased in the former 7 days of the anaerobic stage, average daily gas yield is 169 ml, the number of protein anaerobic ammonifying bacteria, denit(?)ifying bacteria, sulfate reducing bacteria, and hydrogenoroducing bacteria delines slowly, and that of methanogenic bacteria begin to decrease after 14 days of anaerobic fermentation, but that of cellulose-decomposing bacteria appeares to increase slowly.The mathod of treating municipal organic refuse using aerobic first and anaerobic fermentation next can solve the problem accumulating a lots of volatile acids in the direct anaerobic fermentation, shorten the cycle and raise gas production rate.

分别采用直接厌氧和先好氧后厌氧方法处理城市有机垃圾,并以稀释法和相应的培养基,用最大可能数量(MPN)法计算发酵过程中主要微生物生理群的数量变化。结果表明:在直接厌氧发酵过程中挥发性有机酸大量积累,最高浓度达35765PPM,日平均产气量只有25.15ml,一般厌氧异养细菌、氨化细菌、产氢产酸细菌比先好氧后厌氧法高,产甲烷细菌比先好氧后厌氧法低210倍。在先好氧后厌氧发酵过程中,在好氧末期挥发酸浓度达9160PPM,在厌氧阶段,挥发酸中的乙酸、丁酸逐渐下降,而丙酸在发酵的前7天有所上升,日平均产气量为169ml;在厌氧阶段,氨化细菌、硝酸盐还原菌、硫酸盐还原菌、产氢产酸细菌有缓慢下降趋势,产甲烷细菌在发酵 14天后才开始下降,纤维素分解菌呈缓慢上升趋势。用先好氧后厌氧方法处理城市有机垃圾能防止挥发性有机酸的大量积累,使厌氧发酵启动加快,可提高产气率,缩短发酵周期。
