Sewage plant | Fu students (certified) | Sewage Co. provides environmental engineering students from Guangzhou Fu. Guangzhou Fu students Environmental Engineering Co., Ltd. (www.fsyhb.com) is specialized in the "sewage treatment equipment, water purification equipment, dust noise cancellation equipment, disinfection equipment, solid waste handling equipment" of the enterprise, the company adhering to the "honesty, hard service "philosophy, to provide you with the highest quality products and services. Welcome to inquire! Contact: Hu large reed. Sewage treatment process engineering (1) artificial artificial biological purification of biological purification is artificially create the conditions so that microbes multiply, artificial domestication of microorganisms, using the method of microbial metabolic degradation of organic compounds in water quality, and is recently at home and abroad for secondary treatment of sewage soil processes. The main advantages are: the treatment effect is stable, you can adjust the processing efficiency of sewage discharge standards within a certain range, the treatment process, felled and small plot. The main drawback is: high investment, high operating costs, management complexity, the need to operate more staff. The main treatment process is as follows: a sewage sedimentation (or flotation) a biofilm a biological filter (rotating biological contact oxidation, activated sludge) an aeration tank (oxidation ditch) precipitation (or flotation) a sterilization A water (2) natural biological purification of natural biological purification treatment, the main use of pollutant concentrations in the soil microorganisms and plant roots or reservoirs of microbial action so that the water is reduced. The main advantages are: low investment (land acquisition costs 10,000 yuan / hm case), low operating costs, simple to manage, and less operator need. Can be used alone, but also with each other to form a coalition deal with the system. The disadvantage is: a large felled area. The main treatment process is as follows: a precipitate a sewage oxidation pond (land treatment) a rapid infiltration (full speed infiltration, overland flow wastewater treatment industry on the one hand, China's sewage treatment capacity is currently still keep up with the rapid expansion of the scale of water pipe network, sludge treatment facilities construction lags behind. On the other hand sewage treatment equipment, sewage treatment rate in China compared with developed countries, there are significant gaps, and the processing load is low facilities. Therefore, China should improve policies and regulations for sewage treatment sewage, sewage system established regulatory system, create a reasonable sewage treatment fee system, foster the development of domestic industries and environmental protection, sewage treatment industry to promote industrialization and marketization. sewage treatment industry is a sunrise industry, development prospects. China will invest in the "Eleventh Five-Year" 300 billion yuan to promote urban sewage treatment and utilization of Chinese sewage treatment industry thus usher in rapid development period.
