Embodiment 1

[0031] Embodiment 1: This embodiment is intended to provide a kind of ecological overflow weir for purifying water quality, mainly used in the sewage treatment work of water conservancy projects, although it has been widely used in lake and river engineering fields for existing traditional overflow weirs, However, many problems are not considered, such as serious water pollution, poor ecological benefits, and obvious deficiencies in purifying water quality and beautifying landscape. Based on this, this embodiment provides an ecological overflow weir for purifying water quality.

[0032] specific structures, such as Figure 1-4 As shown in , the present invention is an ecological overflow weir for purifying water quality, including a dam 1, an upstream retaining weir 2 and a downstream purification device, and there is a gap between the two to form an aeration tank 3, and the retaining weir 2 It is arranged across the piers 1 on both sides, and the water diverting teeth 4 are e...

Embodiment 2

[0035] Embodiment 2: This embodiment is basically the same as Embodiment 1, and the difference lies in the further description of the specific structure of the through abutment 5 in this embodiment.

[0036] specific structures, such as Figure 1-3 As shown in , in this embodiment, the through pier 5 includes a side pier and a middle pier, and the side pier and the middle pier are placed correspondingly along the horizontal center line, the steel wire mesh frame 6 is installed in the installation groove 8 in turn, and the through pier The platform 5 and the steel wire mesh frame 6 form a permeable dam body in the shape of a wide upper and lower narrow trapezoid; through the setting of the side piers and the middle piers, the side piers and the middle piers are placed correspondingly along the horizontal center line, and the through piers 5 and the steel wire The net frame 6 forms a permeable dam body with a wide upper and a lower narrow trapezoid, which can make the water flow...

Embodiment 3

[0040] Embodiment 3: This embodiment is basically the same as Embodiment 1, and the difference lies in the further description of the specific structure of the sludge carrier 7 in this embodiment.

[0041] specific structures, such as Figure 4-7 As shown in , in this embodiment, the sludge balls have a porous structure, which contains abundant microorganisms, and the sludge carriers 7 are evenly filled inside the permeable dam body; through the setting of the sludge balls, the sludge balls have a porous structure , which is rich in microorganisms, which can effectively absorb sludge impurities in sewage and achieve the purpose of sewage treatment. The sludge carrier 7 is evenly filled inside the permeable dam body, which can not only meet the requirements of overflow, but also achieve the goal of purifying water quality. Purpose.

[0042] A vertical slide rail 14 is provided on the inner wall corresponding to the dam 1 and the aeration tank 3. The vertical slide rail 14 is e...

Abstract

The invention belongs to the technical field of sewage treatment, and particularly relates to an ecological overflow weir for purifying water quality, which comprises dam piers, an upstream water retaining weir and a downstream purifying device, when the ecological overflow weir is used, the water level is increased before the water flow reaches the water retaining weir, the fall of the water flow is increased, and the contact between the water flow and air is increased, so that the aeration in the water body is improved; water diversion teeth are uniformly arranged at the top of the water retaining weir, so that water flow uniformly and crossly flows into the aeration tank along the water diversion teeth, the contact between water and air is further expanded, suspended solids in the water can be prevented from sinking, and the contact between organic matters in the water and microorganisms and dissolved oxygen is enhanced, thereby ensuring that the microorganisms in the water have sufficient dissolved oxygen. Organic matters in the sewage are oxidized and decomposed, so that water pollution is effectively improved and treated; the multiple permeable abutments are arranged at intervals in the transverse direction, the adjacent permeable abutments are connected together through the steel wire net frames to form the combined permeable dam body, the permeable dam body is filled with the sludge carrier, and the sludge carrier can effectively adsorb sludge and can purify water flow, so that the purposes of effectively treating sewage and purifying water are achieved.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to an ecological overflow weir for purifying water quality. Background technique [0002] With the continuous expansion of cities in my country and the rapid development of industry and agriculture, or affected by surface sewage and industrial drainage, many domestic rivers have problems, and the water quality of river courses has been in a poor state for a long time. The purpose of purifying water. [0003] Although the traditional overflow weir has been widely used in the field of lake and river engineering, many problems have not been considered. The sewage has a certain landscape ecological overflow weir to solve the problem. Based on this, it is necessary to study an ecological overflow weir to purify water. SUMMARY OF THE INVENTION [0004] Aiming at the defects and problems existing in the existing equipment, the present invention provides an ecologica...
