Abstract

The invention discloses an environment-friendly mixed wastewater treatment system, the system comprises a water collecting tank, a first reaction tank, a first coagulation tank, a first flocculation tank. a first sedimentation tank, a comprehensive regulation tank, a second reaction tank, a second coagulation tank, a second flocculation tank, a second sedimentation tank, a middle pool, at least one biochemical pool and a third sedimentation tank, a high-concentration wastewater inlet is arranged on the water collecting tank, and a low-concentration wastewater inlet is arranged on the comprehensive regulation tank; a plurality of upper water fenders are arranged on one side of the first sedimentation tank, one side of the second sedimentation tank and one side of the third sedimentation tank from top to bottom, a plurality of lower water fenders are arranged on the other side of the first sedimentation tank, the other side of the second sedimentation tank and the other side of the thirdsedimentation tank from top to bottom, and the upper water fenders and the lower water fenders are staggered mutually. According to the invention, the system centrally treats high-concentration wastewater and low-concentration wastewater, the structure of the system is simplified, the energy consumption is low, the treatment effect is good, and the system is easy to generalize and implement.

Description

technical field [0001] The invention belongs to the technical field of waste water recovery and treatment, and in particular relates to a treatment device capable of simultaneously treating high-concentration waste water and low-concentration waste water. Background technique [0002] With the rapid development of industry, the types and quantities of wastewater have increased rapidly, and the pollution of water bodies has become increasingly widespread and serious, threatening human health and safety. Since the components of industrial wastewater are more complex and some are toxic, it is necessary to treat industrial wastewater in a targeted manner. [0003] High-concentration organic wastewater mainly has the following characteristics: First, the concentration of organic matter is high, and COD is generally above 2000mg / L, and some even reach tens of thousands or even hundreds of thousands of mg / L. Relatively speaking, BOD is low, and many wastewater BOD and COD The rati...
