water environment treatment equipment

General introduction

The water is considered as one precious resource which is necessary for human productive activity and their life. As to the traditional water conservancy projects, which mainly concentrated in controlling, training ,distributing, conserving , developing and using the surface water or ground water existing in the river channels in the nature, they were constructed to fulfill the goals in promoting the benefit and abolishing the harm. These conservancy projects have been covered the different type of hydraulic structures, such as dams, water gates, spillway, channels etc. In order to meet the function of shipping, irrigation, discharging the flood and generating the electricity, plenty of hydraulic structures were built in the world.

In recent years, along with gradually raising of the environmental awareness in China, the traditional water conservancy projects will be given the new requirements which focus on the environmental protection, ecological restoration, human landscape etc. For the river, besides the previous functional requirement, its new requirements of environmental protection and ecology are increasingly prominent in aspect of the water environment, ecology landscape, water demand of ecological environment and biological diversity maintenance etc.

The rivers, especially urban rivers, its ecological control is not only a water conservancy project but also is an integrated engineering which covers the various field such as water conservancy, environmental protection, gardens and municipal administration. The idea of ecological control gradually shifted away towards the integrated construction idea which combines ecology, environmental protection, landscape, security, resource and culture.

Solve the main problem

Complete set of key technology and design support

Cross-sectional - trapezoidal cross-section, rectangular, compound section. According to each section of the design flood standard, channel width and top of each river land properties of the surrounding area to select the optimal cross section.

Smooth connection profile, upstream and downstream river and water level. Control the river flow, as far as possible make it can't satisfy no deposit velocity. It should be considered on both sides of the high embankment and river water elevation.

Slope protection form, traditional form of protection such as concrete, such as slurry masonry appearance more rigid, single, has been gradually replaced by soft ecological protection measures. Urban river, in particular, because the flow velocity is small, can choose ecological bags and ecological stone cage bags, etc.

River water hydraulic structure design and construction

Hydraulic hinge dam water conservancy science and technology - a revolutionary achievement of dam technology is currently the world's leading activities. Mechanical structure science, don't stop water, not afraid of silt deposition and is not affected by debris. In the case of minimal loss of water will make it easier to develop upstream of the floater, make the water clear. Put a dam does not affect the flood control safety fast, firm structure and reliable, flood water impact ability

Water landscape functions can be widely used in irrigation area water resources regulation and recycling. Such as in yunnan guangnan county, which were the management idea: the design of a river for agriculture irrigation problem facing the area along the river and the non-point source pollution problem, through the organic combination of water conservancy engineering and ecological engineering, contribute to optimal utilization along the river irrigation area water purification cycle, achieve the dual purpose of water saving and environmental protection.

Rubber dam is made of high-strength adhering with rubber, which forms a rubber bag anchoring on basement floor of dam. The crest of dam is used for water retention and the height of dam can be adjusted as required so as to control upstream water level.

Hydraulic drop structure includes slope (single-stage slop and multistage slopes), hydraulic drop and pond (single-stage hydraulic drop and multiple hydraulic drops). There are five components of the structure, upper area of control, gap control, hydraulic drop or slope section, stilling basin section and downstream connection.

Another hydraulic structures—culvert, overflow dam, access bridge, patrolling road, etc.

River Water Purification and Riparian Buffers Design

River water ecological restoration——1) Aquatic and amphibious biological diversity and the construction of food chain in water habitat are the key of water ecological restoration. With the aquatic vegetation that submerged plant and floating-leaved plant give priority to the application of absorbing and transforming nutrient in water and bottom mud. For example, hydraulic, waterweed, hornwort and eel grass. Complemented by aquatic species construction, such as various fish, snails, etc. so that we could maintain ecological balance to reach the purposes of purifying water and stabilizing ecosystem function. 2) Construction of river way habitat, such as spawning site, feeding ground, rest area and passageway.---Providing fishes and aquatic invertebrates with life area through river ecological technology. The common technological method is to build a place by simulating the preference of aquatic, like the structure of fish way, shoal or pool, matrix restoration, random riprap and T-shaped dam setup, etc.
