Poverty Reduction,Environmental Protection and Ecosystem Services:A Prospective Theory for Sustainable Development

Poverty reduction and environmental protection are two global tasks for sustainable development.The study perspective has changed over time,from narrowly focusing on poverty reduction to comprehensively strengthening human-welfare.We reviewed key references targeting the theoretical content and practical approach relying on poverty,environment protection and ecosystem services.We discussed the contradicting views on the relationship of poverty and environmental degradation,and then illustrated the study progress of a cutting-age topic-ecosystem services which pave a way to address poverty reduction and environmental protection together.At last,we investigated essential factors that affect the development and environmental protection.Considering the evolution of the concept of poverty,we found that the environment has occupied an increasing proportion in the cognizance of poverty.The relationship between poverty and environmental degradation is regional uniqueness.In practical aspect,projects based on the management and valuation assessment of ecosystem services draw researchers′attention all over the world.The appropriate scale,essential economic incentives,morality,law and social equality are key factors affecting individuals′decisions which directly relate to the sustainable development.

Influence factors analysis of removing heavy metals from multiple metal-contaminated soils with different extractants

Some key factors on the heavy metals removal efficiencies were studied when soil washing technology was used in the remediation of soils contaminated by multiple heavy metals. The results show that the dissolubilities of Cu and Zn are promoted by humic acids, but Pb and Cd are inhibited by humic acids; heavy metals in the clay are more difficult to be extracted than silt; the strong acidic soils can cause the protonation of EDTA and weaken its extracting ability; EDTA is effective for extracting Pb and Cd, while oxalate (OX) is effective for extracting Cu and Zn; and biosurfactant can be used as additive to improve the removal of some particular heavy metals.

Subjective annoyance caused by indoor low-level and low frequency noise and control method

The influence of low_level noise has not been widely noticed. This paper discovered that low_level and low frequency noise(A_weighted equivalent level L eq <45 dB) causes higher probability of subjective annoyance. The fuzzy mathematic principle was applied to deal with the threshold level of subjective annoyance from noise in this study; there is preferable relationship between the indoor noise and noise annoyance at low frequency noise level. Study indicated at the same centered noise level, the change of annoyance probability is mainly caused by the change of the frequency spectrum characteristic of the indoor noise. Under low noise level environment, without change of the medium_low frequency noise, the slight increase of medium_high frequency noise level with the help of noise sheltering effect can significantly reduce the noise annoyance. This discovery brings a new resolution on how to improve the environmental quality of working or living places. A noise control model is given in this study according to the acoustic analysis.

Groundwater protection:What can we learn from Germany?

For drinking water security the German waterworks proceed on a comprehensive concept,i.e.,the protection of all the regions from the recharge area to the client.It includes the protection of the recharge area by a precautionary management,a safe water treatment,a strict maintenance of the water distribution network,continuous control and an intensive training of staff.Groundwater protection zones together with effective regulations and control play a very important role.Three protection zones with different restrictions in land-use are distinguished.Water in reservoirs and lakes is also protected by Surface Water Protection Zones.Within the surrounding area the land-use is controlled,too.Special treatment is necessary if acidification happens caused by acid rain,or eutrophication caused by the inflow of sewage.Very important is the collaboration between waterworks and the farmers cultivating land in the recharge area in order to execute water-protecting ecological farming with the aim to reduce the application of fertilizers and plant protection agents.Probable financial losses have to be compensated by the waterworks.

Length polymorphisms for intergenic spacer regions of 16S-23S rDNA in members of the new hydrogen-producing bacteria

A method based on PCR amplification of the 16S rRNA gene (rDNA)-23S rDNA intergenic spacer regions (ISR) was developed for the identification of species within the novel group hydrogen-producing anaerobes. The sizes of the PCR products varied from 1264 to 398 bp. Strain of isolate Rennanqilyf 3 was characterized as having products of 1262,398,638,437 and 436 bp. The isolate Rennanqilyf 1 had product of 1264 bp. The isolate Rennanqilyf 13 had products of 1261,579 and 485 bp. Of the 3 species of the novel group hydrogen-producing anaerobes examined, no one was indistinguishable. Two environmental isolates were identified as hydrogen-producing bacteria, which were new species in present taxon. Rennanqilyf 3 could not be associated with any Clostridium sp. studied. Rennanqilyf 1 could be classified into Clostridium genus. The combination between 16S rDNA equencing and length polymorphisms of IRS in 16S-23S rDNA is a better method for determining species of the hydrogen-producing bacteria.

Activated Carbon Adsorption Properties of the Residual Matters in Textile Dyeing and Printing Secondary Effluent

The research employed the adsorption isotherm measurement, the batch kinetic adsorption and the rapid small-scalecarbon column test （RSSCT） to find out the characteristics and main impacting factors of＇granular activated carbon （GAC） adsorption, in treating the textile dyeing-printing/polyester alkali de-weighting secondary effluent （TSE）. The adsorption affinities and capacities for the organics surrogated by CODCr, color and UV254 （UV absorbency-at λ= 254 nm） predicted by isotherm, small- seale-fixed bed were discussed. ＇Adsorption rates for CODCr, color and UV254 are much different and carbon particle size dependent. The color adsorption rate and capacity should be taken as the main consideration factors in designing bioactivated carbon filter（BACF）. The breakthrough of GAC adsorption column is mainly influenced by the low MW readily adsorbable organics in TSE. UV254, is a good adsorption breakthrough indicator. The study provides references for BACFs＇ design and operation control in textile secondary effluent （TSE） tertiary treatment.

Enhancing Phosphorous Recovery in a Novel Biofilter System

Developing new techniques to remove and recover phosphorous simultaneously from wastewaters is very important for sustainable utilization of phosphorous resource and prevention of eutrophication. The feasibility of phosphorus bioaccumulation in a novel continuous alternating anaerobic /aerobic biofilter and benefits of such accumulation for its further recovery as magnesium ammonia phosphate (MAP) were studied. The system was operated for seven months and employed the atomic absorption spectrophotometer (AAS) method to analyze the distribution change of magnesium and calcium with phosphate in the biofilter during that period. The benefits of utilizing the biofilter system to accumulate phosphorous & magnesium and suppress calcium simultaneously to phosphorous recovery as MAP were explained with the aid of chemical equilibrium models. The improved phosphorus recovery from 42% to 82% was approved in the recovery experiments and the recovery products mainly as MAP were evidenced and characterized with scanning electron microscopy (SEM) . The study provides references for designing and operating the novel alternating anaerobic /aerobic biofilter for phosphorus bioaccumulation and recovery.
