污水污泥

The results could provide reference data for control of phosphorus re-release in sludge treatment at SBR sewage plants.

试验结果可以为SBR污水厂污泥处置过程中控制富磷污泥磷的再释放提供参考。

The results showed that the sorption was primary and degradation was second of the active sludge.

结果表明，在 A/ O工艺处理城市污水过程中，活性污泥的吸附作用是主要的，降解作用是次要的；A/ O工艺所排放的活性污泥仍然是一种危险的污染物。

No primary sedimentation tank, which made fresh wastewater and SS directly enter into A-step, improved sedimentation performance of activated sludge, and microbial supplement could be gamed from inflow, which maintained concentration of sludge;microorganism phase in reactor was very abundant and there were many sessile vorticella.

AB法不设初沉池，新鲜污水及SS直接进入A段，改善了污泥沉降性能，并可以从进水中得到微生物的补充，以维持反应器污泥浓度，生物相丰富，有大量固着型钟虫。

Seawage sludge from Lanzhou Qilihe sewadge purification factory was applied onto Bromus inermis grassland during 1996 and 1998 with three years monitoring, aboveground yield increase on Bromus grassland with appropriate sludge application was 163~203 percent in 1996, 41~120 percent in 1998. Root biomass increase in 1996 was 35~106 percent higher than the control.

为此，笔者於1996~1998年将兰州市七里河区污水处理厂生活污泥施於无芒雀麦人工草地。3年来对无芒雀麦和土壤进行多项监测，结果表明，施用适量污泥对无芒雀麦地上生物量增产幅度显著，1996年为163%~203%；1998年为41%~120%。1996年总根量比对照高35%~106%。

In this research, we consider that the predominant bacteria in low temperature wastewater treatment in winter were cold-adapted microorganisms, the number of which increased as the temperature dropped more and more, but rarely high up to the number of mesophilic bacteria in normal temperature due to its low growth rate and the restriction of ecological factors, so that the total number and activity level of microorganism in activated sludge decreased.

随着污水温度的降低，污泥中冷适应微生物的数量逐渐增加，但由于冷适应微生物的生长速率相对较低，且容易受到各种生态因子的抑制作用，其数量无法达到常温下中温微生物的水平，使得污泥中微生物的总体数量和活性降低。

The invention belongs to the technical field of environmental protection and in particular relates to a method for utilizing the fermentation effect of microbe in remained sludge to increase the propionic acid content in organic acid which is produced under the normal temperature through replenishing carbohydrate and controlling the pH value when in reaction, the method takes the remained sludge of sewage treatment plants and mixture of urban putrescible organic waste which is produced in everyday life as raw materials.

本发明属于环境保护技术领域，具体涉及一种通过补充碳水化合物和控制反应时的pH值，以污水处理厂的剩余污泥和日常生活中产生的城市易腐有机废物的混合物为原料，在常温条件下利用剩余污泥中微生物的发酵作用提高所生产有机酸中丙酸含量的方法。

The properties of purified terephthalic acid waste mud in the process of PTA sewage tank were introduced briefly.

简要介绍了精对苯二甲酸生产过程中，外排至污水厂活性污泥处理池中形成的污泥废料的性状。

The fresh dewater digested sludge of municipal wastewater treatment plant was suited for vaccinal sludge at the startup of anaerobic reactor and the concentration should not be less 10mg/L; the COD of feed wastewater should be lower than 5000mg/L, and VOL was 20 percent of total VOL; the alkalinity of effluent should be more than 3000mg/L; on the condition of the COD removed 80% can the VOL be elevated.

反应器启动时接种污泥可以选用城市污水处理厂新鲜的脱水消化污泥，浓度不低于10mg/L；进水有机物浓度不高于5000mg/L，容积负荷为满负荷的20％；出水碱度要高于3000mg/L，温度稳定；在有机物的降解率达到80％后再提高负荷。

The possibility of using dewatered sludge from brewery wastewater treatment plant as seed sludge in municipal wastewater treatment plant s was investigated.

试验结果表明，啤酒污泥完全可以作为城市污水处理厂的接种污泥使用，而且培养时间短，出水水质好。

The dewatered sludge was added with various additives to be landfilled,and the variation of heavy metal speciation in sludge during initial and final landfill stages was investigated.

采用不同添加剂与污水处理厂的脱水污泥进行混合填埋，考察了填埋初期和后期污泥中重金属形态的变化。

Plunder melds and run with this jewel!

掠夺melds和运行与此宝石！

My dream is to be a crazy growing tree and extend at the edge between the city and the forest.

此刻，也许正是在通往天国的路上，我体验着这白色的晕旋。
