Abstract

The invention discloses a method for determining a distance between ascension pipes of a sewage deep-sea discharge diffuser. The method comprises the following steps of: estimating the distance of the ascension pipes of the diffuser and determining a primary scheme of the distance between the ascension pipes of the diffuser; establishing a diffuser drainage sea area physic test model and carrying out calibration analysis on the model; testing the physic model of the distance scheme of the ascension pipes of the diffuser; and analyzing the data of the physic model test of the diffuser and determining the distance between the ascension pipes. By comprehensively adopting formula calculation and the physic model test, the method for determining the distance between ascension pipes of the sewage deep-sea discharge diffuser determines the length of the distance between the ascension pipes of the diffuser exactly, solves the current situation that the traditional distance of the diffuser is difficult to determine precisely only by the virtue of the formula calculation efficiently, guarantees dilution and diffusion effects of the pollutants discharged by the diffuser in the sea area, enables the dilution degree of the scope having 100 m distance to the outlet of the diffuser to be 100 times to the maximum, avoids project waste caused by overlong distance of the diffuser, provides technical support for the determination of the length of the diffuser and the design of the economic and environment-friendly type diffuser, and lays the foundation for the sewage deep-sea discharge project.

Description

technical field [0001] The invention relates to a method for determining the spacing of ascending pipes of a deep-sea sewage discharge diffuser, in particular to a design method for a multi-rising pipe and multiple nozzle structure of a sewage deep-sea discharge diffuser. Background technique [0002] Deep sea discharge of sewage is the most environmentally friendly and economical method of sewage treatment near ports, and it has been widely adopted by coastal cities. The optimal design of the diffuser structure is one of the key technologies in the construction scheme of the sewage discharge project. The structural scheme mainly includes the length and pipe diameter of the diffuser, the distance between the number of rising pipes and the pipe diameter, the horizontal azimuth angle of the spout, the jet angle and pipe diameter and other factors. The diffuser structure scheme directly affects the effect of sewage dilution and diffusion and project investment. To study the ef...
