SBR application of integrated wastewater treatment equipment

Colonization. At the same time. Shorter sludge age can not cross to the large population of filamentous bacteria. Thus to overcome the conventional activated sludge bulking disadvantages easy to make. 12SBR process features of law (1) The process is simple, structures less. The process need not set the return sludge facilities. No secondary sedimentation tank, aeration tank volume is less than the traditional customers continuous activated sludge method, the costs are low. (2) under normal circumstances. No need to set regulation pool, according to omit the primary settling tank water quality. (3) SVI value is low, the sludge easy settlement, difficult to produce sludge expansion. (4) Run a flexible, easy to operate to meet the different treatment goals. By adjusting the operation. Not only the removal of COD, nitrogen and phosphorus and can be effective. (5) adaptability to changes in water quality and quantity, water quality and stability. (6) management convenient, easy to realize automatic control, operation, reducing the number of managers and workers in the labor intensity. 13 Decanter SBR process is a more mature biological wastewater treatment technology, engineering practice has proved more of their worries. SBR process is the most critical part of the supernatant discharge device - Decanter. Decanter main functions: (1) Decanter drainage in the set period of time. Sludge without disturbance so as not to discharge the case of floating sludge supernatant, ensuring drainage smoothly; (2) Decanter with devices to prevent the scum out; (3) near the surface of the water catchment agencies, with the supernatant water level changes. 2SBR integrated wood processing equipment, sewage masonry requirements on the process of biological treatment processes and the relationship between the research question, the use of SBR technology and oxygen utilization efficiency, low noise, jet aeration technology, developed a new,[link widoczny dla zalogowanych], Higher Education's SBR Integrated biological treatment facilities. The equipment consists of SBR bioreactor, Decanter, diving jet aerator, cabinet composition, the ideal solution to the traditional integration of the di[link widoczny dla zalogowanych]vantages of biological sewage treatment facilities. 3SBR integrated biological treatment effect analysis of the operation of equipment to a base of students Shanhaiguan if sewage treatment works,[link widoczny dla zalogowanych], for example, the main source of masonry as sewage water, bath water and washing water daily. 3l size of the project design parameters: 120t13 / d; design of water: COD,: 4OOmg / L, BOD5 = 150mg / L, SS = 300rag / L; design of the effluent: COD ≤ 100mg / L, BODj ≤ 30mg / L. SS ≤ 30mg / L. 32 process is the processes and parameters: a septic tank sewage regulation of a pool of a sBR grid integration of a biological wastewater treatment equipment for a discharge or reuse. Process parameters: (1) a grid of large floating debris retention. Designed with a 10mm stainless steel mesh to provide blue-style grille. Department placed the population regulation pond, regular cleaning; (2) adjust pool underground reinforced concrete structure, size (4.0z3.0 × 2.5) m. Built wQ15 enhance a i0-10-type submersible sewage pump 2 sets (1 with 1 to prepare) (3) sBR integrated biological wastewater treatment equipment, steel structures buried, in × H = 4200tam × 42O01] lnl, equipped with a displacement of 30m, b of the decanter find 1 set, 4.0kW underwater jet aeration machine 1, operation cycle 6h; (4) time and the electronic control system uses two-level control, automatic operation, manual backup. Average daily consumption 38.5kW/h3.3 running water quality since 1998, water has been stable, no special management by the local environmental protection department repeatedly sampling inspection, the demand good water quality. In which treated wastewater disinfection by simple reuse of 50%, mainly for the base of the fountain, washing, flowers and fruit trees irrigation. Test results in Table 1. Table 3.4 Water Quality Monitoring in Table 1 according to the original design of sludge disposal,[link widoczny dla zalogowanych], sludge discharge to a septic tank, sludge cycle more than 3 months, each time sludge is less than 5m. However, since the beginning of 1998 the project has been put into use (more than 2 years since Pat), not row through regular monitoring of the sludge through the sludge settlement ratio (SVI), the system has been operating normally. Never happened sludge expansion. 4 Conclusion (1) SBR biological treatment equipment can be integrated to achieve anaerobic, anoxic and aerobic biological processes, sewage and washing water of life have good treatment effect. According to the different needs of users. To address water reuse or discharge standards. (2) When the sewage water is small, the choice of a single SBR integration of biological sewage treatment equipment requirements. When sewage water is large, the choice of 2 units or more integration of SBR biological treatment equipment,[link widoczny dla zalogowanych], the water, aeration, reaction, sedimentation, drainage runs in chronological order to achieve continuous SBR system out of the water.
