The application discloses a kind of urban river channeling ecological construction methods, it is related to river ecological restoration technical field, including the following steps: the hardening cement part of channeling river bottom is crushed to form channeling river crushing layer;Grid cement grid is laid on channeling river crushing layer;Submerged plant is planted in grid cement grid, according to water environment, biological is added, to create pool bottom biological diversity ecological group, along the direction of river channel, the construction of urban river channeling ecology is built.The application not only reduces the occupation of river to urban land under the premise of retaining ecological system, but also saves urban livable environment, reduces river restoration cost;Through the interaction of river bottom and groundwater, the circulation system of river water and groundwater is built, the near-natural restoration of urban channeling river is better realized, the inherent microbial population of river is protected, and the self-purification capacity of river is realized.

This invention relates to the field of environmental water conservancy and ecological restoration technology, and discloses a method for evaluating the effectiveness of river restoration based on multi-source data. The method includes: collecting target and measure-type indicator data; preprocessing the data; dividing the indicators into time-series and non-time-series types; applying exponential time decay weighting to the time-series indicators to generate time-series characteristic weighted indicators; performing robust standardization of the median absolute deviation with the non-time-series indicators to generate a standardized indicator dataset; calculating the proportion and information entropy of each standardized indicator within each sample to construct the total information entropy; calculating the residual average sum using the equally weighted average as the measured effectiveness value and the initial weighted average as the simulated effectiveness value; constructing a joint loss function; solving for the function with the goal of minimizing the joint loss function to generate the optimal weights for each standardized indicator; and finally calculating a comprehensive restoration effectiveness index to quantitatively evaluate the river restoration effect. This invention enables quantifiable and comparable evaluation of restoration effects in different watersheds and at different times.

The application relates to the technical field of sewage treatment, in particular to an ecological-protection river-repairing sewage treatment equipment and a treatment method, which comprises a bottom plate and a mixing barrel and further comprises a supporting mechanism, a water storage frame and a water containing barrel which are installed on the top of the bottom plate, the supporting mechanism is used for supporting the mixing barrel, the application can filter plankton and the like first, then mix flocculants with sewage, the equipment can scrape the bottom of the inner wall of the net-shaped frame, the water source which is preliminarily treated can be further treated through solid fillers, and the treated water source can be directly discharged back to the river to reduce the possibility that the water source is polluted again due to a long discharging process, the problems that the current part of the equipment has high cost, is not suitable for small rivers, it is time-consuming and labor-consuming for workers to salvage plankton and garbage, and part of the equipment is difficult to quickly treat flocculation in sewage treatment, thereby affecting the overall efficiency of river treatment are solved.

The application discloses a slow-flowing river ecological restoration method, and relates to the technical field of river restoration.The method comprises the following steps: 1) preparing an ecological restoration carrier; 2) determining the ecological suitability of river bottom sludge; 3) dividing the river into different regions; and 4) restoring the ecology of the river.The present application divides the slow-flowing river with mild pollution into different regions according to the survival rates of aquatic plants, and uses different ecological management schemes accordingly.The survival rate of the seedlings of submerged plants in the slow-flowing river section after management is significantly improved, and about 60% of the riverbed is covered by the submerged plants.

The application relates to the field of riverway repair, in particular to a flexible protection structure for riverway repair, which comprises gabion units, Reno mattress units and reinforced macadam units, the gabion units are hexagonal and have continuous net surface structures, are filled with stone materials, and multiple gabion units are stacked into gabion retaining walls; the Reno mattress units are laid on the bottom of the riverway, are also hexagonal and have continuous net surface structures, and are filled with stone materials; and the reinforced macadam units are laid on vegetation slopes and have continuous net surface structures. The net surface structures of the units have specific weaving and connecting modes, for example, the gabion units are woven by first steel wire meshes, the connecting positions are alternately twisted by single turns and double turns, and reinforcing ribs are arranged; the Reno mattress units are woven by second and third steel wire meshes, and have partitions to form unit chambers; and the reinforced macadam units are provided with U-shaped nails inserted into the vegetation slopes. The application has the technical effects of effectively repairing the riverway, enhancing the structural stability of the riverway, and protecting the ecological environment around the riverway.

The utility model relates to treatment equipment for riverway restoration, which belongs to the technical field of riverway restoration and comprises a filter box, a filter plate hinged inside the filter box and an impurity discharge port arranged on one side inside the filter box, and a suction mechanism extending into the filter box is arranged on the upper surface of the filter box. And the suction mechanism comprises a first double-shaft motor fixedly mounted on the upper surface of the filter box and a first rotating disc fixedly mounted on an output shaft at the right end of the first double-shaft motor. According to the treatment equipment for riverway restoration, a first rotating disc is driven by a first double-shaft motor to rotate, then a connecting shaft and a piston rod are driven to do reciprocating motion in a pump body, effective suction of sewage is achieved, the sewage is conveyed into a filter box through a liquid outlet pipe, and meanwhile the first rotating disc and a crank are driven by the first double-shaft motor; the filter plate vibrates up and down, so that efficient suction and quantitative filtration of sewage are realized, the treatment efficiency is improved, and the advantage of efficient suction and filtration is achieved.
