Embodiment Construction

[0030] See figure 1 First, after calculating the residence time required for contact disinfection according to the amount of sewage in the hospital, determine the layout plan of the pipe (canal) and the route and position of the pipe (including well) in light of the actual situation on site; then carry out civil construction, dig trenches, Workover and lay sewage pipes (it can also be built into underground canals with brick masonry) to ensure that the pipes (canals) and wells do not leak; double-layer stainless steel mesh is used to make a round hole sandwich structure (including a ring base and a simple lift. hand), the middle is filled with pebbles, sand, and activated carbon of different thicknesses to make a coarse filter, a medium filter, and a fine filter, which are placed in the coarse filter well, mixing well, and sampling well in turn, and the well cover is covered; The hospital sewage in the pool is introduced into the coarse filter well, flows through the mixing we...

Abstract

The invention discloses a simple disinfection method for medicinal wastewater of a hygiene hospital, and belongs to treatment (CO2F) of sewage. The method solves the problem that no land is available for building a contact disinfection tank when certain small hospitals, hygiene hospitals or clinics treat the medicinal wastewater or the construction of a contact disinfection tank is difficult due to a geologic structure (such as rock). The contact disinfection tank is replaced by using a conduit (channel), and field pavement of a pipeline convenient for surrounding a septic tank or encircling (rounding) arrangement of an outpatient service building is combined according to the practical requirement so as to prolong the length of a contact disinfection pipeline, ensure the residence time after the sewage and a disinfecting agent are mixed and achieve the disinfection effect. The method has the advantages of low investment, convenient construction, strong adaptability and stable disinfection effect, and is suitable for sewage disinfection treatment of small hospitals and clinics in current lacking urban land.

Description

technical field [0001] The invention relates to a hospital sewage disinfection technology, especially suitable for the disinfection treatment of sewage in small hospitals and health centers, and belongs to the sewage treatment category (C02F).
