A method for designing and constructing a rectangular seepage channel with stable water volume, comprising the following steps: digging, dry laying, mortar laying, stone discharge, capping, backfilling a graded pebble filter layer and backfilling a mixed sand and pebble filter layer. Dry masonry is to have water inlet joint arrays at the bottom of the two side walls of the rectangular seepage trench. Mortar masonry is to use at least one of block stones, cement blocks, bricks, concrete prefabricated blocks or concrete tamping to build the two side walls of the rectangular seepage trench to the design total height. The height of the stone-discharging foundation and the bottom height of the two side walls of the dry-laid rectangular seepage trench as well as the size of pebbles, bricks and block stones shall be determined according to the design requirements. It has the advantages of digging and masonry, relatively less affected by landslides, good water inflow effect and stable water volume. The design and construction method of the rectangular seepage canal of the present invention effectively solves the drawbacks of the existing circular seepage canal's water inlet holes being blocked after advanced sand and the water inflow plummets, greatly improves the water production of the water collection and water intake structures, and makes each large mouth The water between the well and the infiltration canal can flow into the water collection structure continuously.

A floating solar array made of a closed loop of flexible high density polyethylene pipes with elbows, T fittings and couplings. An anti-lift membrane fills with water and mitigates the wind forces. The array can have a stabilizing skirt going downwardly from the border of the array, especially when it is used offshore in the sea. A vertical axis tracking system with windlasses, two anchoring points and four mooring lines allows all the solar panels to face the sun throughout the day. For small lakes or mine tailing, the two anchor points will be onshore, on a concrete foundation. Winches to wind and unwind the mooring lines are located at the anchor point or on the solar array. For larger water areas, or offshore applications in the sea water, the anchor points are under water; using typically a concrete block or a suction pile solution for each anchor.

The present invention discloses a construction method adapting backwash devices in water purification floor filtrated layer, it includes water purification floor which is equipped with backwash pipeline, macrostoma sunk wells which are installed along clear-water reservoir and rectangular seep ditches which are installed separately, the macrostoma sunk wells and the rectangular seep ditches are equipped with rectangular belling intake channel separately and are laid and extended towards upstream and downstream of rivers, its upper half pipe wall is also equipped with washing holes and eyelets. It also includes the following steps: (1) digging the filtrated layer in the outer washing zone of water purification floor or back-filling to the design depth;(2) laying the backwash pipes on the bottom of the filtrated layer; (3) filling sand cobble of washing holes and eyelets which size is bigger than upper half pipe wall on the outside of upper half pipe wall to forming surface filtrated layer; (4) casting concrete antiscour pillar on the backwash pipelines on site;(5) covering or filling original filtrated layer flat with river bed. The construction method in the invention can recover or renew the water purification floor filtrated layer in a short time, reduce project investment and water control cost significantly, and can stabilize the water yield of water purification floor in a long term and improve water supply quality.

The invention relates to a rapid manual land infiltration treatment system and a method for purifying river water by applying the same. The treatment system consists of a water inlet pump, a regulating tank, a flow meter, an infiltration tank, a water collecting tank, a water distribution pipe entering the infiltration tank, and a water collecting pipe flowing out of the infiltration tank. Natural sand and at least one of zeolite and lava are used as a filling of the infiltration tank. When in operation, the infiltration tank is biologically domesticated and cultured by means of natural biofilm culturing in advance, is alternatively water-flooded for 12 to 72 hours, and are dried for 12 to 72 hours in 20 to 80 days in total of domestication; river sewage enters the regulating tank after being pumped by the water inlet pump, and are settled for 0.5 to 5 hours in the regulating tank; the settled sewage is distributed by the water distribution pipe and freely flows into the infiltration tank; after the settled sewage is water-flooded for 12 to 72 hours and dried for 12 to 72 hours, the infiltration solution is collected by the water collecting pipe and is then discharged into a river.

The invention discloses a process for recycling electroplating wastewater. The process comprises the following steps: (1) carrying out advanced-treatment pretreatment on the electroplating wastewater; (2) carrying out advanced-treatment aftertreatment on discharge water; (3) enabling treated wastewater to flow through filter paper so as to filter the treated wastewater; (4) pumping the wastewater into reverse-osmosis equipment; (5) carrying out detecting. By adopting the wastewater recycling process disclosed by the invention, requirements of the reverse-osmosis equipment on influent water quality can be met, the water quality of recycled water is stable, normal operation for the reverse-osmosis equipment can be ensured, the reverse-osmosis equipment can normally work for 10 months and even longer than 1 year, and meanwhile, the wastewater of a high-pressure side can be discharged after reaching standard.
