Problems solved by technology

The leading processes of sewage treatment in villages and towns are not the same in different countries. Foreign treatment technologies may not be completely suitable for the characteristics of the domestic economic environment, and cannot be blindly promoted and used. The water treatment technology suitable for my country's national conditions needs further research

Embodiment

[0030] In this example, set the falling water flow rate to 250mL / min, the falling water depth h=20cm, the hole diameter of the perforated strip of the falling water plate=5mm, and the inclination angle α of the deflector 11 in the water falling plate assembly=0°. The total transfer coefficient K of standard oxygen at different water drop heights H=32cm, 40cm, 50cm, 60 cm, 70cm, and 80cm was obtained through the clear water performance test under the conditions of having a water drop board and no water drop board respectively Las .

[0031] The transfer of oxygen in the air from the gas phase to the liquid phase belongs to the process of substance diffusion. According to Fick's law, the concentration difference of the substance on both sides of the interface pushes the substance molecules to transfer and diffuse from the higher concentration side to the lower side, that is, the substance The rate of diffusion is directly proportional to the concentration gradient. Based on the...

Abstract

The invention discloses a water falling plate component and a water falling oxygenation catalytic oxidation ecological ditch. The water falling plate component comprises a guide plate, wherein the guide plate is arranged at a water outlet and is used for guiding water; baffle sides in sealed connection with the guide plate are arranged on two sides of the guide plate; the guide plates and the baffle side form a guide zone; baffle plates in an included angle with a water flow direction are fixed on the guide plate; two ends of the baffle plate are respectively connected with the baffle sides ontwo sides of the guide plate. The height of the baffle plate is lower than those of the baffle sides, and a plurality of baffle plates are arranged on the guide plate in the water flow direction, sothat the guide zone is divided into a plurality of flowing areas; a plurality of through holes are formed in the baffle plates in extension directions of the baffle plates, and adjacent flowing areasare communicated through the through holes; by adopting the water falling plate component, the sewage treatment efficiency in villages and towns can be improved, the effluent quality of sewage treatment and the natural environments of the villages and the towns can be ensured, and the water falling plate component has great significances for comprehensive improvement of villages and towns and ecological civilization construction of China.

Description

technical field [0001] The invention relates to a falling water plate assembly and a falling water oxygenation contact oxidation ecological ditch. Background technique [0002] According to the results of the first national survey of pollution sources (2010), agricultural pollution sources are the main pollution sources of the water environment. Among them, the annual emissions of COD, TN, and TP are 13,240,900 tons, 2,704,600 tons, and 284,700 tons, respectively, accounting for 43%, 57%, and 67% of the total emissions. In recent years, with the formulation and implementation of a series of water pollution control plans in villages and towns, some achievements have been made in the treatment of water environment in villages and towns. However, there are problems such as empty treatment projects in villages and towns and the deterioration of treatment effects. The work of water environment treatment in villages and towns still needs to be further completed. . [0003] At pr...
