Abstract

The invention especially relates to a modularized integrated system and method applicable to treatment of low-temperature livestock and poultry slaughtering waste water in the north, belonging to the technical field of water treatment. The modularized integrated system comprises the following concrete modules: a pre-treating module used for intercepting large pollutants in the livestock and poultry waste water, a primary physicochemical module used for adjusting and biological hydrolysis, a secondary biochemical module and a tertiary in-depth treating module, wherein the secondary biochemical module comprises an anaerobic submodule and an aerobic submodule which are in series connection, and the tertiary in-depth treating module comprises a micro-flocculation submodule, a cloth filter and an ultraviolet disinfection submodule.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to a modular integrated system and method suitable for treating low-temperature livestock and poultry slaughter wastewater in northern China. Background technique [0002] Slaughtering industry is one of the pillar industries for earning foreign exchange and ensuring supply in my country. Poultry slaughtering wastewater is a typical water quality feature: high organic matter concentration, high ammonia nitrogen concentration, and high suspended solids concentration. It is one of the largest sources of organic pollution in my country. Direct discharge will affect Great harm to the environment. [0003] Slaughtering wastewater discharge is large and highly volatile. According to statistics, 100 chickens are slaughtered to discharge wastewater of 1.0-1.5m 3 , slaughter 100 ducks and discharge 2.0-3.0m of waste water 3 , slaughter 100 geese and discharge wastewater ...
