Nguyen Thi Phuong Bac Student ID DTN1153110089 Thesis Title Assessing performance the wastewater treatment of Tan Quang cement factory, Tuyen Quang province Supervisor Dr Nguyen Thanh Hai Abstract: Vietnam is a developing country, so the cement industry has an important role in the development of the country However, wastewater discharged from cement factory cause pollution the environment and affect to human health Tan Quang cement factory went into operation in January 25, 2011 with a capacity of 2500 tons clinker / day, equivalent 910000 tons of cement products PCB40 / year has contributed develop the industry in Tuyen Quang province However, an Lu wastewater from the production process and domestic wastewater have risk of n va causing environmental pollution The evaluation of the performance of wastewater ac th treatment in factory by methods inherited, synthesis, analysis and processing of data d si nl ow helps us know level of impact on the environment After domestic wastewater and d oa cooling water get preliminary treatment of will be concentrate together to treatment an lu After analyzing measurement results samples of wastewater before and after ul nf va treatment can seen that concentration of the substances in water before treatment oi lm and after treatment were almost reached QCVN 40:2011/MONRE, treatment z at nh i z performance of pollutants is high from 68% to 74% To reduce pollution of water, factory need frequent training, propagation officials and staff members conducting well the work environmental protection Check the repair and replacement of damaged equipment Conducting regular environmental monitoring to be able detect environmental problems for timely treatment Key words: Wastewater, performance, treatment, cement Number

each student after their graduation needs to prepare your self for the necessary amount of knowledge, strong expertise During the graduation exercises is an important part indispensable in training programs University students in general and students Thai Nguyen University of Agriculture and Forestry in particular This is about the time needed for each student reinforce the theoretical knowledge learned a systematic way and improve their ability to apply theory to practice With the respect and gratitude, I would like to sincerely thank the teachers of Faculty Environment and the teachers of International Training and Development Center has imparted to me the precious knowledge during learning and training at school In particular I would like to express deep gratitude to Dr Nguyen Thanh Hai has heartedly, guiding them to complete this thesis I would like to express our sincere thanks to the officers Viet - Sing Equipment Corporation has facilitated helping me during practice During practice and as a subject, I tried very hard but due to lack of experience and knowledge is limited so my thesis inevitably flawed I would like to receive the an Lu heartfelt comments of teachers and friends for my dissertation was excellent I would like to sincerely thank! n va Thai Nguyen,September 30th 2015 ac th Student d oa nl ow d si Nguyen Thi Phuong Bac oi lm ul nf va an lu z at nh iii z

PART I INTRODUCTION 1.1 Research Rationale Vietnam development follow path of industrialization - modernization, so there should be focused on the construction and development of infrastructure To satisfie this requirement, the construction plays an important role in that renewal In which cement is an important material in which most countries in the world to use in building works Cement industry in our country are qualified to develop, because our country is rich in raw materials (limestone, clay) and have the conditions of access to the most advanced technology Tan Quang cement factory was Tan Quang Cement Joint Stock Company investment officially went into operation in January, 25th 2011 in Tuyen Quang city with a capacity of 2500 tonnes clinker / day, equivalent 910000 tonnes of cement products PCB40 / year Tan Quang cement factory in operation marked a new development of industrial Tuyen Quang, simultaneously contributing to the objectives an Lu of the Government on development of cement industry Vietnam until 2020, bringing n va the industry Vietnam cement industry to become a strong industry, with modern ac th technology, capable of competing on the domestic market and internationally d si nl ow However, beside the positive aspects achieved, we are facing many d oa environmental problems Wastewater from the production process and wastewater of an lu officials and employees have risk of causing environmental pollution ul nf va Therefore, the evaluation of the performance of wastewater treatment in the oi lm sewage treatment of Tan Quang cement

PART V DISCUSSION AND CONCLUSION 5.1 Discussion Production technology in Tan Quang cement factory is production technology employing the dry method with a rotary kiln system have heat exchange tower and decomposition chamber The level of high automation, the modern facilities are applied to ensure stable production, high productivity product quality reached economic efficiency Therefore this technology is very friendly with environmental, so environmental issues improves our already very significantly Tan Quang Cement Factory use private wastewater treatment and then general treatment by mechanical methods, chemical and biological combining this technology has roughly treated components pollutants in wastewater and cooling water Since the factory installation of treatment systems, the treatment tank is always in active state so wastewater is not stagnant again, and coolant is collected together with domestic waste water so concentrations in water before treatment almost attained QCVN40:2011/MONRE From measurement results and analysis before treatment can an Lu see that concentration of substances as: TSS lower than compared with QCVN n va 40:2011/ MONRE is 1.5 times, concentration BOD5 lower 1.1 times, concentration ac th COD lower 1.8 times d si nl ow Wastewater treatment system was built in late 2013, so treatment performance d oa of pollutants is high from 68% to 74%, some substances such as: TSS treatment an lu performance high reached 72.1(%), treatment performance BOD5 reached 69.6(%), oi lm system treatment very well ul nf va treatment performance COD
