Water Disposal

The task of statistically stable waste water discharge control with measurement control at section lines has been investigated. The method of water disposal correction under the conditions of variability of water indicators to be controlled has been proposed. A decision rule that allows finding out (with the preset level of precision) whether a pollutant concentration in the waste water is kept within the natural background. An appropriate supplement to Excel has been proposed for practical application, including revealing of random short-term disturbances of the water disposal regime.

Water is the basis of natural resources and strategic economic resources.Deteriorated water environment of streams in Shenzhen city could have a great impact on ecological safety, people's health,and economic development.Based on the data of field observation and Remote sensing (RS) image,integrated analysis of the water degradation causes,and the changes of biochemical oxygen demand in five days(BOD5）concentration by mathematical model were carried out,which is on basis of percentage of waste water disposal,fresh water transformation,and harbor excavation, respectively.The results show that degradation causes of water quality were resulted from waste water discharge, harbor construction,and ecological environment damage, which could lead to slowly water exchange. Accordingly,the pollution can be easily to store in the bay,which result in water quality changes.The most important improved countermeasure is the control of waste water, which could be had a great effectiveness to decrease pollution.In addition, fresh water must be supplied after polluted water was cut off,which can be better improvement for water quality.This would be extreme improvement for hydrological dynamics due to 15m harbor excavation,which can significantly reduce BOD5 concentration.The innovation points of this paper is to mathematical model,which is based on the basis of qualitative analysis.

Water waste in Palm Oil Mill (POM) is not effectively utilized yet. Before waste water discharge from POM, the waste water is processed by an aerobic treatment in several ponds to decrease the influence of organic matter. Methane gas generated in the anaerobic ponds is a Green Gas House giving a contribution to global warming impact. In Palm Oil Mill of Sei Silau located in North Sumatera, the potential generated methane gas in two anaerobic ponds has been investigated using measurement of Chemical Oxygen Demand (COD) of waste water in the sites. Based on the potential generated methane gas, the reduction of GHG emission is calculated, and the feasibility of the project as CDM project was evaluated.Keywords : Pabrik Kelapa Sawit, gas metana, gas rumah kaca, proyek CDM (CleanDevelopment Mechanism),, COD (Chemical Oxygen Demand)

Analysis of methodic recommendation on calculation of the relationships and characteristics has been given on the basis of experience in calculation of water/economic balances and water resources abstraction limits, as well as waste water discharge limits for water/economic parts of the Kama River basin within the frameworks of the Scheme of Water Resources Integrated Use and Protection (SWRIUP) development. Some clarification of the above methods has been proposed.
