Through to analysis the influence of the effluent from the sewage treatment plant to the river water quality of Fangshen-Habaqi stream segment in lower reaches comprehensively, in order to achieve water pollution control and water function zone protection. This paper use QUAL2K model to simulate the influence to lower reaches water quality, and the simulation factor is BOD. The result showed that the downstream BOD concentration cannot reach the water quality standards Ⅲ. This paper provides some corresponding control measures, so as to provide the scientific basis of the water pollution control planning research.

A study on the optimization planning of water pollution control for Majiagou Stream in Harbin was carried out. Four water pollution control options were considered. The option regarded as most feasible, both technically and economically, involved the construction and operation of a wastewater treatment works with a capacity of 150,000 m3/day on the upper reach of the stream. The effluent would be discharged into the upper reach of Majiagou Stream and would be used as a water source for the stream, while an interceptor sewer was to be constructed on the lower reach of the stream to collect wastewaters in the lower reach basin and transport them to a centralized wastewater treatment plant. An optimization study of the relationship between the sewerage interceptor and the sewage treatment plant on the upper reach was conducted. In this study, a comprehensive water pollution control plan, including the sewerage system, sewage treatment plant, and the use of treated wastewater as a water source for Majiagou Stream, was considered as a systematic problem in which many factors were taken into account. Cost-benefit analysis was carried out for both the sewage treatment plant and the interceptors by means of empirical regression equations and diagrams in which various curves showed the relationships between the important factors.

Estimation of water quality impacts plays an important role in the planning of water pollution control. In this paper the connection of water quality aspects with the rest of the planning procedure is examined in the light of a case study area, Lake Päijänne in Finland. For this area an integrated water resource development plan was made by the Finnish water authorities. In order to diminish the adverse effects resulting from effluents of pulp and paper mills and municipalities, different pollution control alternatives were drawn up. Next, forecasts about the development of water quality in different alternatives were made. The most important parameters from the point of view of the different modes of water utilization were taken into account. These parameters were oxygen, phosphorus, COD, lignin and colour. In addition, in assessing the impacts, toxity of effluents was taken into consideration. The impacts of these parameters on the usability and utilization of water areas were analyzed. The forecasts of impacts on vacation settlement, water supply and fisheries were made. In the comparison of the alternatives, numerous intangible factors were involved. In the assessment of the alternatives the costs of water pollution control measures, the benefits and the adverse effects were taken into consideration. The impacts of intangible factors were assessed in each alternative by comparing the water use possibilities with the goals that had been set.


A study was carried out to evaluate the performance of Sewage Treatment Plant in Ghumarwin area and the following conclusions have been drawn. The ranges of physical, chemical and biological characteristics of waste water quality which is in the permissible limits given by waste water/sewage effluent standard as per pollution control board. The results of parameters i.e. pH, BOD, COD, TSS, Oil & Grease after the sewage treatment is under the standards limits. The standards of sewage treatment parameters pH, BOD, COD, TSS, Oil & Grease up to 5.5-9.0, 30mg/l, 250mg/l, 100mg/l and 10mg/l. The results of pH, BOD, COD, DO and SS were 7.0 to 7.5, 18.0 to 22.0 mg/l, 150.0 to 165 mg/l, 5.0 to 6.0 mg/l and 50.0 to 56.0 mg/l, which are within the permissible standard limits . In the present study, all the above parameters were compared with the limits given by Pollution Control Board and it was found that all parameters are with in the acceptable limits. Hence it is concluded that performance of Sewage Treatment Plant is good and in working condition.

Changes of microbial indices of water quality in the Vistula and Brda rivers as a result of sewage treatment plant operationThis paper reports the results of studies of microbiological changes in the water quality of the Vistula and Brda rivers after the opening of sewage treatment plants in Bydgoszcz. The study involved determining the microbiological parameters of water quality. Based on the results obtained, it was found that the quality of the water in both rivers had improved decidedly after the opening of the plants, although an increased number of individual groups of microorganisms was found at the treated sewage outlet from one of the plants.

The paper takes the Second Songhua River as an object for research and selects Thomas's BOD-DO stable model as the initial structure on the basis of overall investigations and analyses on water pollution in every reach. In view of the characteristics of the river being located at the north, values k’1, k’2 and k’3 in dry season of winter were determined and calculated, and a series analyses have been made. The self-purification ability of the river and the total elimination amount of the main pollutants BOD5 were also calculated. In order to minimize the required cost, we distributed the cost to the main pollution sources, which are to be controlled. We firstly set a cost function of sewage treatment plant by series design and calculated the related cost parameters, then calculated two kinds of optimal distributing models of BOD5 elimination, which were a mathematical model of extreme value of conditions and a matrix mathematical model. Now they have been applied to the practical pollution control plan for the Second Songhua River.

Water pollution control policies generally direct sources (i.e., industry, agriculture) to reduce loadings of certain pollutants. Thus, evaluating the relative net recreation benefits of policies to improve water quality requires establishing a linkage between the sources, the resultant water quality degradation at the affected water bodies, and, ultimately, the effect on recreation behavior. This linkage is rarely present in the empirical literature which is, thus, deficient for water pollution control policy assessment purposes. In this paper, we estimate the relative recreational swimming benefits that may result from controlling point and nonpoint sources of pollution, respectively, in New Hampshire's lakes. We use a repeated discrete choice framework to model swimming behavior as a function of each lake's level of eutrophication, bacteria, and oil and grease. For each pollutant, at each affected lake, we identify which source is responsible for the pollution, and we conduct scenarios controlling each pollution source independently, and then, taken together. Seasonal benefit estimates are presented for each scenario. Coupled with information on the most cost effective means of generating the scenarios, these estimates provide a useful starting point for a quantitative assessment of the net recreation benefits of policies to improve the quality of New Hampshire lakes.

Beyond the traditional load reduction also an ecosystem-internal mechanism can be used to minimise the effects of water pollution. The control of the internal mechanisms is achieved through the optimisation of the ecosystem structure. This ecotechnology principle is based on the idea to reduce as much as possible the gap between the current (suboptimal) structural status and the optimum structure by intentional manipulations. The spectrum of such manipulations is very broad. A few examples are demonstrated. They comprise physical (e.g. stream morphology), chemical (e.g. enhancing the redox potential at the sediment–water interface) and biological (e.g. enhancing stocks of predatory fishes) control measures. It can be supposed that a new immission concept including the ecotechnology principle could be much more adequate to the demand of modern water pollution control than the traditional emission and imission concepts.
