Preparation method of novel ecological slope protection material

Abstract

The invention provides a preparation method of a novel ecological slope protection material. The preparation method comprises the following steps that S1, sludge is pumped through an environment-friendly cutter suction type dredging pump, filtered through a primary filter screen technology and then enters a sludge storage pool; S2, a microbial deodorant is sprayed in the sludge storage pool for deodorization; S3, the deodorized sludge enters a sludge concentration tank through a pipeline to be pretreated, and the pretreated sludge is conveyed into a mixing tank; S4, crushed slag, fly ash and construction waste are added into the mixing tank to serve as brick making raw materials, the raw materials are mixed with supernate obtained by concentrating and digesting the sludge, meanwhile, a curing agent is supplemented to conduct curing treatment on the mixed materials, and the mixed materials do not form large bonding blocks after being mixed; and S5, static pressure molding is conducted on the mixed materials in the mixing tank through an automatic control brick press, and after molding, the mixed materials are transported into a curing room for curing. By the adoption of the above scheme, harmlessness and recycling of the sludge at the river bottom and the lake bottom can be achieved synchronously, the treatment cost is low, and economic benefits are good.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a preparation method of a novel ecological slope protection material. Background technique [0002] There are many rivers and lakes in southern my country, and the sediment is rich. As an important part of the ecology of rivers and lakes, the river and lake sediment management and the control of internal source pollution of rivers and lakes have become the first means of comprehensive river and lake improvement. In my country, there is a phenomenon of "heavy water and light mud" in the treatment of river and lake pollution, that is, to vigorously carry out water treatment work, but less involved in the treatment of sediment pollutants. In recent years, with the enhancement of national awareness of environmental protection and the call of policies, the control of sediment pollution and its resource utilization have also begun to receive attention. In order to eff...

Problems solved by technology

In my country, there are few methods for the harmless disposal of sludge and its use as building materials, and reasonable and sustainable resource utilization methods are still in the initial stage of exploration
