Abstract

The invention discloses a salt discharge treatment system for a salted reservoir, a building method, and a treatment method for salted water. The salt discharge treatment system consists of movable water collecting wells, water collecting cages, water diversion branch pipes, a main water collecting pipe, a water gathering well, surface flow wetland, a water sinking pond, subsurface wetland and a water storage reservoir, wherein the movable water collecting wells, the water gathering well, the surface flow wetland, the water sinking pond, the subsurface wetland and the water storage reservoir are laid out according to an actual physiognomy; the water gathering well, the surface flow wetland, the water sinking pond, the subsurface wetland and the water storage reservoir are totally seepage-proof water collecting wells, and the salted water is collected by the movable water collecting wells, treated in the wetlands and the water sinking pond and stored in the water storage reservoir for other purposes. The salt discharge treatment system is reasonable in structure, scientific in design, investment-saving, short in construction period, low in water treatment cost and convenient to manage, takes effect fast, can conduct purification treatment at all seasons, produces high-quality water, recovers a self-purification function of a water body, can be used for supplying landscape water, can be closely combined with city landscape construction, realizes water purification, and achieves purposes of conservation and efficient utilization of water resources.

Description

technical field [0001] The invention relates to a sewage treatment system, in particular to a saline reservoir discharge salt treatment system, a construction method and a saline water treatment method. Background technique [0002] At present, there are many reservoirs in the coastal areas of our country, most of which are built on the land retreating from the sea. The subsoil at the bottom of the reservoirs has high salt content, complex terrain, and a large number of dry ponds and highlands. Due to the long-term retention, evaporation, and high salt content of the bottom soil, the stored water in the dry ponds is seriously salinized. When water is transferred to the reservoir, the newly transferred water source will be mixed with the high-salt water storage, causing the salt content of the water body in the reservoir to increase sharply, and the water body is seriously salinized, causing the reservoir to lose its water source function. Contents of the invention [0003...
