Problems solved by technology

At the same time, the load of the oxidation ditch is low and the sludge age is long, so that most of the activated sludge microorganisms in the oxidation ditch are in the state of endogenous respiration, the sludge is aging, and the aged sludge flocs are easily broken by aeration, thus forming floating sludge

Embodiment Construction

[0042] Embodiments of the present invention are described in detail below in conjunction with accompanying drawings:

[0043] like figure 1 and figure 2 As shown (the direction of the arrow is the direction of water flow), the water treatment device for tidal surges of the present invention includes: an oxidation ditch 1, which is constructed on both sides of the river, and forms an S-shape in the lateral direction of the river. Ditch body, the two ends of the S-shaped ditch body communicate with the river, and the two ends are the water inlet and the water outlet respectively; the water inlet and the water outlet of the oxidation ditch 1 are respectively provided with an aeration device 21, 22 ; and biofilm treatment device 3, which is located in the oxidation ditch 1.

[0044] Combine the oxidation ditch technology with the river itself, build an S-shaped oxidation ditch on the river, and through the combination of the oxidation ditch 1 and the aeration device 21, 22, for...

Abstract

The invention discloses a tidal river surge water treatment device. The tidal river surge water treatment device comprises an oxidation ditch, at least two aeration devices and a biofilm treatment device, wherein the oxidation ditch is built along both sides of river surges and form an S-shaped ditch body in the transverse direction of the river surges, both ends of the oxidation ditch, used as a water inlet and a water outlet, are communicated with the river surges; the aeration devices are respectively arranged at the water inlet and the water outlet; and the biofilm treatment device is arranged in the oxidation ditch. The tidal river surge water treatment device applies the oxidation ditch technology in a long and narrow river course environment, combines the oxidation ditch technology and the biofilm technology and has the advantages of the oxidation ditch technology and the biofilm technology. The oxidation ditch provides a relatively stable growing environment for microorganisms, thus the microorganisms are enriched in the oxidation ditch, high sludge concentration is kept and pollutants are degraded; and the biofilm technology is easy in management and the defects of the oxidation ditch such as the floating and swelling of sludge can be overcome.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a water treatment device for tidal surges. Background technique [0002] With the rapid economic development of our country, especially the Pearl River Delta region, the development of urban infrastructure cannot keep up with the increase in population, and a large amount of domestic sewage is directly discharged into nearby water bodies without treatment. Many urban rivers receive a large amount of sewage, which far exceeds their self-purification capacity. Organic pollution leads to rapid consumption of dissolved oxygen in the water. The development of cities urgently needs to develop effective governance technologies to control pollution and restore damaged river ecosystems. [0003] The existing river pollution control technologies can be divided into three categories: physical technology, chemical technology and biological ecological technology. [0004] Physical techniques...
