The design of the sewage from the main production process rinse water production equipment, workshops ground water irrigation. The wastewater to the high concentration of organic wastewater, sewage biodegradability general. Removal of the contaminated material general to ensure that water quality at the same time, a reasonable balance between economic and operational management of the scientific, and consider wastewater standards. Sewage Treatment Process : UASB anaerobic tower, biological oxidation, precipitation and filtration. Sludge treatment and disposal of used filter Van reductions after progressed. Gate residue and sludge treatment and disposal : artificial grid gate slag using artificial periodic cleaning, and in conjunction with other garbage disposal progressed. UASB anaerobic tower, two settling tank sludge into sludge pond, concentrated filtration dehydration, dry sludge progressed. Dealing mainly with the full use of existing structures pools, such as the regulation of tanks, sludge tanks, intermediate pools, additional biological oxidation pond Shen two pools, which mainly deals with the structure to take the floor-half. Major processing equipment and room-to take the floor and make a building on the ground decorative landscaping, to the park and building style. Blower through the noise gate, slag and sludge dewatering progressed, and other measures to eliminate secondary pollution, The entire operation will not affect the existing environment, which greatly improved the water quality. The station design consists of sewage treatment and sludge treatment and disposal of two parts. In sewage treatment, according to water, water quality changes, combined sewage own unique circumstances, mature technology, economic rationality, Operation flexible, easy management, stability of the treatment program. In the sludge treatment and disposal, sewage treatment sludge from the process, there should be stability, prevention of environmental pollution secondary; and proper consideration of the final disposal of sludge. Sewage treatment technologies are summarized below : 1. Trash wastewater facilities (the pharmaceutical wastewater) contains all kinds of floating material, need to be installed grid interception. To prevent follow-up to plug the pump or processing equipment; Avoiding the follow-up pool with precipitation increasing number of repair. Artificial grid with low cost, grid interception gate Jardine artificial cleaned regularly. 2, the regulation of water quality due to emissions of sewage water quality is very uneven, causing water from sewage water, water fluctuations, and Therefore, only large enough capacity to regulate access to biological treatment so that the quality of water stability it must have uniform regulation pool, the balance of quantity and quality, reduce follow-up structures to deal with the impact load. 3, biological treatment of sewage pond after regulation after regulation uniform, using anaerobic biological treatment and aerobic biological treatment of the most economical technology, biological process : through domestication and cultivation advantages of having a microbial groups, Growth in the use of the surrounding environment of nutrients in the water that is contaminated substances metabolism, Degradation of pollutants reached, the purpose of purifying water. Biological Process biological growth by the state, is activated sludge, biofilm. Activated Sludge Process biological bacteria in the form micelles suspended in the water through aeration sewage mixed decomposition of pollutants. Activated Sludge Process according to their mode of operation are : general aeration tanks, oxidation ditch, SBR, anoxic - oxic, A/A/O. mainly used in large-scale sewage treatment plant. SBR addition, the provision required sludge return pump, more equipment, the SBR, Small sewage treatment works are also used, but SBR design loads smaller, 0.1kgBOD5/m3?d generally, the application covers a large area, as Decanter needs greater depth of the pond, Meanwhile more control equipment, once the equipment malfunctions or changes in operating parameters, have to run the whole adjustment process. Meanwhile small sewage treatment using activated sludge process, prone to sludge bulking sludge caused the loss, processing pools of sludge concentration is not assured, thus affecting the result. A design principle, the design of the program to strictly enforce the state environmental protection requirements, Sewage treatment must ensure that the effluent quality indicators discharge standards. 2, a simple, mature, stable and practical, economical and reasonable treatment process to ensure that the effect of treatment, savings and investment, operation and management costs. 3, equipment selection balance between general and advanced, reliable operation, high efficiency, easy management, repair and maintenance amount. affordable. 4, the system flexible, easy management, maintenance simple, as far as possible automation of operation, and reduce labor intensity operation. 5, aesthetic design, rational layout, and existing facilities to consider harmonization. 6, and set up the necessary monitoring instruments, and improve operational control of the degree of automation. 7, taking measures to reduce the impact on the surrounding environment, the reasonable control of noise, odors and proper treatment and disposal of solid waste, prevent secondary pollution. Finally the water should reach the People's Republic of China "effluent discharge standards" (GB8978-1996) 2 standards.
