Effect of Expansion of Urban Region on Soil Animals in Farmland Ecosystem: A Case in Shenbei New District in Shenyang City, Liaoning Province

Shenyang Biosolids Composting Plant is a one-of-a-kind facility that is designed to handle and treat up to 1,000 tonnes of 80% moisture content wet biosolids per day from four municipal wastewater treatment plants (WWTPs) that have a combined capacity of 1,600 MLD in Shenyang City, Liaoning Province, China. The composting plant covers an area of approximately 130,000 m2. The moisture content of biosolids will be reduced to 35% by biodrying. The main facilities in the plant include the materials handling and mixing system (for wet sludge, raw material and compost), the agitated composting bed system, the ventilation and odor control system, the truck scale unit, the storerooms (for raw material and product), and the other auxiliary facilities. The design has incorporated the necessary environmental considerations for the protection of workers’ health and safety as well as the potential impacts on the neighboring communities. The finished compost product will be sold as soil amendment and/or auxiliary fuel. In comparison with other technologies, this plant is favored for the low capital cost (0.279 million RMB per wet tonne of sludge), the low operating cost (173.13 RMB per wet tonne sludge) and the low energy consumption/carbon footprint. The plant is currently under construction. The installation works of No.3 composting train is scheduled to be carried out in June 2012. When the plant is commissioned in September 2012, it will become a sustainable solution to the sludge problem in Shenyang City.

Reported Study

The article is devoted to the architecture of the preserved historical buildings of the consular offi ces of Shenyang City in Liaoning Province during the fi rst half of the 20th century. During the period under review, consulates of countries such as Britain, France, Japan, Germany, Italy, America and Russia were opened. In the process of research, four surviving objects were identifi ed, in which Japan, Germany and France were located. Their compositional and stylistic analysis with a brief historical description is carried out. In particular, it was determined that mainly buildings selected as consular offi ces or built directly for them were located in the central administrative region. Currently, the preserved objects are included in the list of monuments of the architectural heritage of Shenyang. The reported study was funded by RFBR, project number № 20-012-00316

At present, the problem of rural domestic garbage pollution in China is relatively serious, which restricts the sustainable development of rural areas. Therefore, it is very important to investigate and analyze the characteristics of rural domestic garbage generation and discuss countermeasures for the treatment of domestic garbage. This article is conducted a one-year follow-up survey of the characteristics of garbage generation in Zhenshang Village, Central Village, and Natural Village in Fushun City, Anshan City, Dandong City, Shenyang City, Tieling City, and Panjin City in Liaoning Province. Background, the amount, physical composition and change trend of rural domestic garbage were analyzed, and on this basis, countermeasures for rural domestic garbage treatment in Liaoning Province were proposed.

Leaching Risk

A field experiment was conducted at the vegetable production base of Lixiang town in Shenyang city, Liaoning province to study the effects of dicyandiamide (DCD) application on the accumulation and leaching risk of soil nitrate. The results showed that applying DCD significantly decreased the amount of soil NO3--N in the 0-10cm and 10-20cm soil layers compared to without DCD addition (P < 0.01). However, the difference was not significant in the 20-40cm (P > 0.05). These results indicated that the application of DCD reduced the leaching risk of soil nitrate from topsoil to subsoil. At the 28d of fertilizer application, the amount of soil NO3--N was higher in the NP+M, NP+M+2%DCD and NP+M+5%DCD treatments than in the M, M+2%DCD and M+5%DCD treatments, suggesting that the combined application of chemical fertilizer and organic manure weakened inhibiting effect of DCD on the amount of soil NO3--N.

A study was conducted to evaluate the water quality parameters of pond water at Mymensingh Urban region. The water samples were collected from 30 ponds located at Mymensingh Urban Region during August to October 2010. The chemical analyses of water samples included pH, EC, Na, K, Ca, S, Mn and As were done by standard methods. The chemical properties in pond water were found pH 6.68 to 7.14, EC 227 to 700 ?Scm-1, Na 15.57 to 36.00 ppm, K 3.83 to 16.16 ppm, Ca 2.01 to 7.29 ppm, S 1.61 to 4.67 ppm, Mn 0.33 to 0.684 ppm and As 0.0011 to 0.0059 ppm. The pH values of water samples revealed that water samples were acidic to slightly alkaline in nature. The EC value revealed that water samples were medium salinity except one sample and also good for irrigation. According to drinking water standard Mn toxicity was detected in pond water. Considering Na, Ca and S ions pond water was safe for irrigation and aquaculture. In case of K ion, all the samples were suitable for irrigation but unsuitable for aquaculture.J. Environ.
