Pollution of surface water in rural areas in china remained serious, analysis the main pollution sources. Figure. 1 shows that the average concentration of COD from township enterprises was about two times the national average. Figure. 2 and figure. 3 shows that amount of fertilizers and pesticides use basically increases year by year and annually are enormous. Agricultural pollution is more serious than industrial pollution,untreated domestic sources of pollution and livestock breeding were harm to water environment in rural areas.

The construction and development of township enterprises plays a key role in promoting the development of rural economy. With the implementation of the rural revitalization strategy, township enterprises develop rapidly, but there are problems in the development process that have a negative impact on the quality of local rural water environment. Rural water environment is related to the health of farmers, the healthy development of agriculture and the sustainable development of rural areas, so it is necessary to predict the water pollution of township enterprises. The application of support vector regression forecasting model to the prediction of water pollution of township enterprises can better predict the water pollution of township enterprises with the characteristics of complexity, nonlinear and small sample. This intelligent forecasting method will help to scientifically prevent the development of township enterprises from having negative impact on the quality of local water environment.

In recent years, with the degree of urban-rural integration, the economic level of rural areas and the improvement of residents’ health awareness, the water quality pollution of rural domestic sewage has increased year by year, and the problem of rural sewage discharge has become increasingly prominent. In order to improve the rural water environment and solve the problem of random discharge of sewage, this paper takes the rural domestic sewage as the research object, and takes the natural sedimentation and anaerobic fermentation as the main means to study the on-site resource utilization technology of sewage. It was found that after 3 hours of sewage sedimentation, organic suspended solids settled naturally, resulting in a significant decrease of COD in the upper sewage to 93.29 mg/L. Because of the special bimolecular structure of LAS, the concentration of LAS in surface sewage increased sharply to 7.68mg/L, but it was lower than 10mg/L, which met the irrigation water standard.

The experience of importing Simmental breed from Austria of beef cattle Hereford breed from Novosibirsk region, red steppe breed from the Altay Territory to the Republic of Sakha (Yakutia) is analyzed. Acclimatization of imported livestock to the conditions of the Far North is hard. Of 471 heads of cattle of Austrian Simmental breed imported in 2007, 171 are currently left. The average milk production of cows per head is 2485 litres, the average figure for the Republic is 2364 litres. Of 200 heads of Herefords brought in 20112012, only 32 have remained. A brief description of the milk productivity of the red steppe breed in Yakutia is presented. Milk yield per cow amounted to 2630 litres in six lactations, which is 166 litres higher than the national average. Due to non-compliance with the requirements of the technology of keeping and feeding imported animals, 116 out of 200 imported cows have remained. The hematological parameters of cattle reflecting the state of the body's immune system during acclimatization are given. Adaptation of red steppe cows was difficult, but the hematological parameters corresponded to the physiological norm. Possible ways of developing livestock breeding programme in Yakutia to create a simmentalized Yakut zonal type of cattle, which is distinguished by exceptional adaptive abilities for keeping and feeding conditions, are proposed. Thanks to crossbreeding with Yakut cattle, the acclimatization and further breeding of imported specialized breeds and their crosses is successful. The ways of improving the technology of keeping and feeding cattle on the farms of the Republic are shown.

Sources Of Pollution

The protection of the environment and people’s health from negative influences of the pollution of air as a medium of the environment requires constant observing of the air quality in accordance with international standards, the analysis of emission and imission of polluting matters in the air, and their connection with the sources of pollution. Having in mind the series of laws and delegated legislations which define the field of air pollution, it is necessary to closely observe these long-term processes, discovering cause-and-effect relationships between the activities of anthropogenic sources of emission of polluting matters and the level of air degradation. The relevant evaluation of the air quality of a certain area can be conducted if the level of concentration of polluting matters characteristic for the pollution sources of this area is observed in a longer period of time. The data obtained by the observation of the air pollution are the basis for creation of the recovery program of a certain area. Vranje is a town in South Serbia where there is a bigger number of anthropogenic pollution sources that can significantly diminish the air quality. The cause-and-effect relationship of the anthropogenic sources of pollution is conducted related to the analysis of systematized data which are in the relevant data base of the authorized institution The Institute of Public Health Vranje, for the time period between the year of 2012. and 2017. By the analysis of data of imission concentrations of typical polluting matters, the dominant polluting matters were determined on the territory of the town of Vranje, the ones that are the causers of the biggest air pollution and the risk for people’s health. Analysis of the concentration of soot, sulfur dioxide and nitrogen oxides indicates their presence in the air of Vranje town area in concentrations that do not exceed the permitted limit values annually. The greatest pollution is caused by the soot content in the air, especially in the winter period when the highest number of days with the values above the limit was registered. By perceiving the influence of natural and anthropogenic factors, it is clear that the concentration of polluting matters can be decreased only by establishing control over anthropogenic sources of pollution, and thus it can be contributed to the improvement of the air quality of this urban environment.

The paper reports the main findings of a study, designed to develop a better understanding of institutional variations in working with the demand responsive approach (DRA) in rural water supply in the state of Odisha in India. Data for the paper were collected from twelve village communities, where water is being supplied either through their community based institution or through the local government institution of the Gram Panchayat. The findings suggest that the two types of institutions performed differently in implementing the DRA. It depicted that the DRA under the broader rubric of institutional reforms in the water sector has failed to address the question of social inequality, and rather had reinforced and extended the already existing inequity of Indian society to access to safe and secure drinking water in rural areas. The study highlights that participation, cost recovery, full operation and management transfer may be an efficient proposition, but not sustainable in the long run without proper investment in institution building and support from the state, especially in provisioning of basic services like drinking water to rural poor.

Source of water is the beginning of rural drinking water projects, safe water source is the key to rural drinking water safety. Status of rural drinking water source in china and laws and regulations on rural water conservation were analyzed. The population of centralized water supply accounts for 51% of the total population in rural areas in 2008, centralized water supply 49%. Groundwater source accounts for 57% of the population of centralized water supply projects in rural areas in 2008, surface water sources 43%. China has a relatively sound legal system of drinking water source, including basic law, general law, administrative regulations, local regulations.The paper draws a conclusion that sources of drinking water in rural areas is mainly groundwater, water conservation is short of specific laws and regulations and not suitable for rural area,it is necessary to improve laws and regulations on rural water conservation, government must assume responsibility for rural water conservation, especially financial investment and public policy support.
