The most goals were to evaluate the current status of wastewater in Nui Phao Mining Company and to propose a few estimations to diminish water contamination as well as to diminish the release of wastewater into clean water sources. A considerable amount of wastewater must be treated and released to the right location within the company.
The bio-digester-treated influent significantly reduced water quality parameters such as natural oxygen demands (BOD), chemical oxygen demands (COD), ammoniac nitrogen (NH3-N), and added to suspended solids (TSS). The corporation has started building a wastewater treatment system that can effectively process wastewater and oversee wastes release at the expo. The ii basic arrangements are developed after examining the situation within the production plant. In terms of management, the corporation should follow tight procedures for trash treatment and wastewater discharge into the environment.
When it comes to innovation agreements, the corporation has chosen appropriate options.

Research rationale Water, like air and light, is one of the most important resources in everyday living. Water and the environment play a critical role in the formation of life on Earth. Water is involved in practically every aspect of life and production. “Water is one of the most basic of all needs - we cannot live for more than a few days without it.
And yet, most people take water for granted. We waste water needlessly and don't realize that clean water is a very limited resource. More than 1 billion people around the world have no access to safe, clean drinking water, and over 2.5 billion do not have adequate sanitation service. Over 2 million people die each year because of unsafe water - and most of them are children.
Science and innovation have accelerated the speed of socioeconomic development in recent years, resulting in a vast array of cloth items to fulfill people's growing demands. In any event, the financial development, particularly the rapid development of the sector in recent years, has resulted in a large amount of squander water. Typically the coordinating cause of natural contamination in general and the deterioration of water quality in particular, resulting in pure water becoming increasingly scarce and exhausting on the world. In recent years, Vietnam has advanced the possible expansion of the nation's industry, the benefits that sustainable mechanical advancement has brought, which are demonstrated through financial, natural, instructive, and social advancement.
4 In any case, along the positive comes about of mechanical improvement, it too causes negative impacts on the environment and society, especially on the water environment. In which the environmental pollution caused by the mining and processing activities is not effectively managed that is one of the issues that are of interest in the past. In which the environmental pollution caused by the mining and processing activities is not effectively managed that is one of the issues that are of interest in the past. At the same pace of development in the whole country, Thai Nguyen province has also brought into full play the strengths and resources to promote socio-economic growth, apart from the industrial parks which have been completed, mineral resource exploitation projects have contributed to the development of the province.
The Nui Phao Mining and Processing project in Dai Tu district is a large project contributing greatly to the development of the province in terms of economy, politics and society in recent years. Research’s objectives - Assessment of wastewater treatment from the mining and processing activities of Nui Phao Mining Company. - Identify sources of water pollution caused by the mining activities - Propose some measures to prevent pollution in the area's water environment. Research questions - What is an overview of Nui Phao Mining Company Limited? - What is the situation of exploitation and use of water of Nui Phao Company? - What are possible solutions to reduce water pollution of the Nui Phao Mining Company Limited and its impacts to human and environment for? 5 1.
Limitations - Due to limitation of time and resources, this study mainly focuses on the water pollution in Nui Phao Company. - The measurement and sampling time were done everyday. So, the samples could reflect the water pollution in company. - This study solely mentions to the wastewater of the Nui Phao Company in st st short term of the January 1 2021 to June 1 2021 periods.
Definitions This study was conducted to analyze the status of Nui Phao Mining Company Limited's wastewater treatment from January 1st 2021 to June 1st 2021 in order to estimate the impact of wastewater on the environment. Thus, a number of solutions are proposed to mitigate the negative effects of wastewater to the environment surrounding the company.
