The results show that bioleached sludge at pH 3.5～1.95 can be used successfully as inoculums for the next batch bioleaching trial with the similar bioleaching efficiency,by which pH of the treated sludge can be reduced to less than 2 within 5 days for hydraulic residence time of bioleaching.

结果表明，用淋滤过程中pH3.5～1.95的生物酸化污泥作菌种，污泥的pH值都能够下降到2.0以下，而且不同pH值的生物酸化污泥作菌种的淋滤效果差异并不显著，说明淋滤过程中pH在3.5以下的污泥都可以作为菌种，接入到下一批次待处理的污泥中进行生物淋滤。

ResultThe result showed that compared with our country sludge agricultural use's standard, the content of the chromium, the cadmium, the nickel, and the copper wdid not surpass the permission level in three kinds of sludge samples. But in the yellow clay the zinc content exceeded the allowed figure seriously, both white clay and black clay reached the standard.

结果］与我国污泥农用标准相比，铬，镉，镍，铜4种重金属在3种污泥样品中的含量都没有超过允许的水平，但锌在黄泥中的含量严重超标，在白泥和黑泥均达到标准。

It was the use of natural plant cassava cirrhosa the juice as a natural dye, various textile dyeing, textiles repeatedly disseminated, and placed under the scorching sun, they have become brown and yellow semi - use the iron-rich black pond sludge silt on one side or double-sided smear, we can wait until the surface was black, buffeting from pond sludge silt, clean, become yellow-faced Lane, shiny lights textile fabrics.

是利用天然植物薯莨的汁液作为天然染料，将各种纺织品进行染色处理，对纺织品反复多次浸染，并放在烈日下曝晒，使其变成棕黄色的半成品，再拿富含铁质的黑色塘泥对其单面或双面涂抹，待其表面生成黑色，抖脱塘泥，清洗干净，就成了面黑里黄，油光闪烁的纺织品面料。
