This invention relates to the field of ecological corridor planning technology, and more particularly to a method for planning ecological corridors in waterfront blue-green spaces. The method involves obtaining multiple comprehensive schemes that include blue-green space connectivity layout, ecological corridor resilience node planning, stormwater storage facility configuration, and slow-traffic recreation space optimization. Each scheme is applied to a simulated plain water network waterfront scenario, generating a stormwater storage-slow-traffic recreation collaborative dataset reflecting its actual performance. Through multi-dimensional verification of the collaborative dataset in terms of stormwater storage capacity, slow-traffic recreation suitability, ecological connectivity resilience, and cost feasibility, feasible schemes are selected and preferentially used in actual construction. This improves the adaptability and recovery capacity of the blue-green space system in response to extreme rainfall, while optimizing slow-traffic network connectivity and waterfront space user experience, enhancing the scientific nature and feasibility of planning decisions. This method is applicable to the resilient planning and construction of ecological corridors in plain water network areas.

The disclosure teaches a scrubbing or buffing or cleaning adapter for use with power tools. The adapter is made of a storage tank or container. The storage tank is designed to be filed with a liquid solution. The liquid solution may be a detergent, soap, plain water, a buffing compound or any other liquid solution. The liquid solution is poured into the storage tank prior to usage through a refill opening or an outlet opening. The outlet opening preferably contains a pump or suction mechanism that is configured to transfer the liquid solution from the tank into the hose. The hose then channels the liquid solution to a spout or an inlet spout of a spinning attachment. The suction or pump mechanism is powered by an onboard power supply and is operated electronically through a switch or manually through a crank handle).

The utility model discloses a water purifier which comprises a purified water supply unit and a water purification unit, the heating unit is used for heating purified water in the first water storage unit; a second water storage unit; a heat exchange device; the first water storage unit is communicated with the second water storage unit through the first water path; the second water storage unit is communicated with the first water storage unit through the second water path, and the first water storage unit, the first water path, the second water storage unit and the second water path can form a circulating water path, so that water flow circularly flows between the first water storage unit and the second water storage unit; and the like. By arranging the circulating water path, the water flow circularly flows between the first water storage unit and the second water storage unit by utilizing the density difference of water, and the problem that the temperature of cold boiled water is reduced due to heat dissipation of the second water storage unit storing the cold boiled water is solved.

The present invention belongs to the technical field of flood risk assessment, specifically a method for risk assessment and analysis of excessive rainstorms in plain water network areas, comprising the following steps: a first step: data collection, obtaining comprehensive data of the area to be assessed, the comprehensive data including: topography, hydraulic pipe network, hydrological water collection, station gates, river network and river channels, embankments, past rainfall and humanities information; a second step: module coupling: building a comprehensive data module for the area to be assessed based on the obtained comprehensive data, and constructing a three-dimensional model of the area to be assessed through the comprehensive data module; a third step: model verification; a fourth step: rainfall simulation; a fifth step: result output; by establishing multiple data modules, coupling the multiple data modules into a regional model, and simulating rainfall through a rainfall module, real-time calculation of the occurrence of rainstorms in the assessment area is achieved, which is more in line with the actual situation of the assessment area, thereby achieving the effect of improving the accuracy of risk assessment.

This application provides a water purification method applicable to plain water network areas, comprising: (1) investigating and analyzing the hydrodynamic and water quality characteristics of canals in plain water network areas; (2) selecting characteristic degrading microorganisms and immobilizing them on a biological absorption plate; (3) during the dry season, setting up a biological absorption plate mainly composed of anaerobic or facultative anaerobic bacteria inside the canal; (4) during the wet season, setting up a biological absorption plate mainly composed of aerobic or facultative aerobic bacteria on the canal slope; and (5) regularly managing and maintaining the biological absorption plate to ensure long-term water quality maintenance. This method is applicable to the efficient purification of polluted water bodies in canals of plain water network areas under different hydrodynamic conditions, solving the problem of water purification materials hindering flood discharge, and overcoming the problem of microorganisms being unable to effectively attach due to canal hardening. It can rebuild the natural ecology to a certain extent, enhance the self-purification capacity of the water body, and achieve a good ecological landscape and long-term maintenance of water environment quality.
