River ecologic purifying system, and making method of ecologic concrete products

Abstract

The invention relates to a river ecologic purifying system, and a making method of ecologic concrete products. The system comprises a plurality of ecologic concrete products laid at the river bottom and on the bank, the upper surfaces of the ecologic concrete products are provided with upper flow guiding holes, the lower surfaces of the ecologic concrete products are provided with lower flow guiding holes, the apertures of the lower flow guiding holes are smaller than the apertures of the upper flow guiding holes, flow guiding pipelines for connecting the upper flow guiding holes with the lower flow guiding holes are arranged in the ecologic concrete products, and the surfaces of the flow guiding pipelines are provided with microbes or water plants. The making method of the ecologic concrete products comprises the following steps: adding 50% of gravel while stirring, adding 10% of sludge with the water content being smaller than 80% while stirring 5min later, adding 20% of common nitrate cement while stirring 5min later, adding 1% of water while stirring 5min later, adding 15% of fine sand while stirring 5min later, adding 2% of water while stirring 5min later, adding 2% of a water reducer while stirring 5min later, using a molding die after uniformity to prepare concrete, and curing the concrete under dry and ventilating conditions for 30d or heating for drying and solidifying to obtain the ecologic concrete products. The system can effectively and ecologically reconstruct the river bottom and improves the river water purifying effect.

Description

technical field [0001] The invention mainly relates to the technical field of environmental water treatment, in particular to the technical field of river water purification. Background technique [0002] my country's urban water pollution is very serious. About 90% of the country's rivers are polluted to varying degrees. Among them, the pollution of black and smelly rivers in cities has been pushed to the forefront. Among the series of quantitative goals set by the "Water Pollution Prevention and Control Action Plan" promulgated by the State Council in April 2015, "Urban Rivers and Lakes Black and Odor Water Treatment" is considered to be the most difficult - five years to build prefecture-level cities and above cities The black and odorous water bodies in the district are all controlled within 10%, and the urban black and odorous water bodies will be eliminated within 15 years. The ecological system is facing many problems, and the degradation of the ecological system has...
