The purpose of this paper is to analyze the sludge characteristics of the Qingdao Ni Buwan Sewage Treatment Plant and introduces the sludge disposal technique in recent years and designs an incineration working procedure on power station. The method used in our study is known as directly heat dry-cure incineration technique for generate electric power in Qingdao Jiaonan Power Co., Ltd. We have carried out several sets of experiments to test the validity of incineration generate electric power. The results of the experiment indicate that this incineration program is practicable, resolves the sludge disposal problem in Qingdao Ni Buwan Sewage Treatment Plant and has effect and profit in economic , social and environment.

By aerobic composting bin type of sewage treatment plant sludge composting, through periodic sampling, research composting process temperature, moisture content, PH value changes and study the changes in compost maturity parameters of the DH. The results show that the compost temperature increased rapidly in the early rise in the first two days when fast to 50 degrees Celsius, in the tenth day decreased to room temperature; moisture content than the original sludge reduced by 40 percent to compost indicators; PH by reaction initial 6.2, and gradually becomes neutral and alkaline 7.8 biased. Experiments show that after aerobic sludge composting in temperature, moisture content, PH value terms have been reached sludge disposal requirements.

Abstract A comparison of costs of implementing an advanced wastewater treatment system for a cadmium plating plant, versus the sludge disposal costs of the sewage treatment plant to which the plating plant is discharging its effluent, is described. An economic analysis spreadsheet approach using Lotus 1-2-3 is employed. A case study application demonstrates for overall society net benefit that it is cost-effective to initiate pretreatment at electroplating facilities which allows a municipal facility to dispose of its sludge on agricultural land rather than be required for landfilling. Sensitivity analyses to market interest rate, sludge production, sludge disposal fees and drag-out rates are explored.

Even in Japan, the energy recovery from a waste became the importance by not only wastetreatment problem but also environmental problem which carbon dioxide (CO2) causes. Theenergy recovery is being measured from organic waste. However, the construction of thedisposing facility does not advance in actually various factors. As the one factor, the property ofa organic waste variously changes by the discharge source such as home, food shop, supermarket, farm, sewage treatment plant, etc., and the energy recovery ratio changes with it. In thisstudy, the biogas generation of the waste which arose actually was obtained experimentally. Inaddition, the following were examined using waste generation in the region and the biogas frombiowaste : Electric power recovery, heat recovery, CO2 emission. In the garbage discharged, thegas generation magnification showed the very high, The gas yields seemed to be very high forbiowastes, since these is originally offered as foods. In case of the livestock manure, the gasyield over about 16 times per manure was obtained. The gas yield is not very dependent on theorganic substance content. This cause the bedding was included in the manure, and it seemed toaffect the organic substance content by the content and type. In case of the sewage sludge, thegas yield of about 3.5 times per sludge was got. As a result of the trial based on the wastegeneration in the region, electric power, heat can be utilized effectively. In addition, that thereduction was also possible on CO2 emission clarified.

As part of the regional sludge disposal system of recycling to land, which is integrated into the Niers river basin management of the Niersverband, FRG, pasteurization is done in combination with the anaerobical stabilisation of sludge in order to ensure a long-term agricultural disposal with respect to hygienic hazards which is in general much less expensive than any other alternative sludge handling and disposal. During the past 15 years of Niersverband activity in liquid sludge recycling pasteurization has been done after digestion, mostly by flash heating along the CANZLER process with steam. Alternative heating by submerged combustion here has been proved reliable after nearly 10 years experience of several installations of this kind for raw sludge pasteurization with oil fuel supply. Submerged combustion heating with digestion gas supply has been running at a medium sized sewage treatment plant (100.000 population equivalents) during the past two years. The pasteurization, which was first done after digestion, was now successfully put in front of the anaerobical stabilisation with sufficient gas yield, organic matter degradation, and stable low concentration of organic acids (CH3 COOH) in the digester at a positive gas energy balance.

Sewage sludge incineration residue was obtained from a sewage treatment plant in Guangzhou and used as a low-cost sorbent for removing Ni2+ from wastewaters. The adsorption effectiveness and their factors of Ni2+ in aqueous solutions were simulated detailed using the adsorbents of the sludge incineration residue. The simulation contents and the factors included the adsorption time, the pH of solution and the dosage of adsorbents and so on. The results showed that at room temperature, the adsorption equilibrium of Ni2+ can be achieved in 6h and the best pH value of the solution was about 7.0. The removal rates of Ni2+ were increased with the adsorbent concentration increasing and the optimal concentration of adsorbent was 10g/L with the initial concentration of Ni2+ less than 30mg/L.At the best adsorption conditions, the removal rate of Ni2+ reached more than 70%.

Sewage sludge incineration slag, the waste generated in sewage sludge incineration, was obtained from a sewage treatment plant in Guangzhou and used as a low-cost sorbent for removing Cu(Ⅱ) from wastewaters. The adsorption effectiveness and their factors of Cu2+ in aqueous solutions were simulated detailed using the adsorbents of the sludge incineration slag. The simulation contents and the factors included the adsorption time, the pH of solution and the dosage of adsorbents and so on. The results showed that at 30 °C, the adsorption equilibrium of Cu2+ can be achieved in 6h and the best pH value of the solution was about 4.5-5.5. The removal rates of Cu2+ were increased with the adsorbent concentration increasing and the optimal concentration of adsorbent was 20-30g/L with the initial concentration of Cu2+ less than 25mg/L.At the best adsorption conditions, the removal rate of Cu2+ reached more than 80% and the adsorption capacity was 0.83-1.25mg/g.
