Integrated water treatment device having function of carrier flocculation sedimentation

Abstract

The invention discloses an integrated water treatment device having a function of carrier flocculation sedimentation. The device comprises an integrated pool body. The integrated pool body comprises a coagulation tank, a sand addition tank, a flocculation tank and a high speed sedimentation tank. A water inlet pipe is connected to the coagulation tank. The water inlet pipe is used for injecting sewage and a high-efficiency coagulant into the coagulation tank. The upper end of the coagulation tank is communicated with the upper end of the sand addition tank. The sand addition tank is used for adding micro-sand into sewage. The lower end of the sand addition tank is communicated with the lower end of the flocculation tank. The flocculation tank is used for feeding a coagulant aid into the sewage after reaction in the sand addition tank. The upper end of the flocculation tank is communicated with the upper end of the high speed sedimentation tank. The high speed sedimentation tank is used for separating water and alumen ustum particles in the sewage after the reaction in the flocculation tank. The high-speed sedimentation tank is externally connected to a muddy sand separator. The device has the advantages of flexible design, compact structure, small covering area, impact resistance, high treatment efficiency, low cost and strong load capacity, and can be used for purification of black and smelly polluted water and treatment on industrial wastewater having high content of suspended solids.

Description

technical field [0001] The invention relates to an integrated water treatment device with carrier flocculation and sedimentation functions. Background technique [0002] Due to insufficient urban infrastructure construction, with the accelerated development of urbanization and industrialization, rivers and lakes in some cities, especially sewers and rivers in small and medium-sized towns, have directly become the main discharge channels and places for industrial, agricultural and domestic wastewater, resulting in Urban water bodies are polluted on a large scale, and water bodies become eutrophic, forming black and smelly water bodies. [0003] Due to historical reasons, many stone processing enterprises were originally located in the upper reaches of the city. The construction of stone processing projects lacked planning and management, construction was scattered everywhere, and environmental protection facilities were not complete. A large amount of production wastewater co...

[0003] Due to historical reasons, many stone processing enterprises were originally located in the upper reaches of the city. The construction of stone processing projects lacked planning and management, construction was scattered everywhere, and environmental protection facilities were not complete. A large amount of production wastewater containing high-concentration suspended solids (SS) was discharged into the The downstream river section not only wastes a lot of precious water resources, but also causes serious pollution to the environment; similarly, the ceramic industry is developing rapidly, and the wastewater produced by the ceramic industry has a large amount of sewage, a high concentration of fine solid particles, and a large SS (generally in the 1000~10,000mg / L) and difficult to biodegrade; most of these wastewaters are directly discharged into the river without treatment, which poses a serious threat to the ecological environment of the river

[0004] Loading flocculation sedimentation technology is a rapid flocculation sedimentation technology, which is characterized by adding high-density insoluble medium particles (such as micro-sand) in the coagulation stage, and using the gravity settlement of the medium and the adsorption of the carrier to accelerate the "growth" of flocs And sedimentation. Compared with the traditional flocculation process, this technology has the advantages of small footprint, low engineering cost, and impact load resistance. In recent years, loading flocculation sedimentation technology has been widely used in domestic water supply and sewage treatment fields, but the operating effect is different. very big
