Technology of cleaning reservoirs with the disposal of alloys and sludge in fertilizer.
Technology of purification of reservoirs and lakes from all types of algae and feces into fertilizers.
When cleaning the lake from vegetation: algae, peat and sapropel (rafting), the processing produces a highly effective organic-mineral fertilizer, which is so necessary for agriculture.
Pure Nature Corporation offers a technological solution and equipment for cleaning overgrown reservoirs and natural lakes from plant and peat-sapropel deposits with their preparation and processing into paste-like or loose fertilizers. Especially for farms and small enterprises, technological solutions were proposed for the integrated use of algae, vegetation, peat and sapropel, extracted during the cleaning of lakes.
The complex includes: a business feasibility study, equipment for cleaning the tank, preparation and processing of the recovered mass into fertilizers and fertilizer mixtures.
Initially, peat-silt sediments are investigated on the lake, the depth and conditions of its occurrence, the quantity and area of vegetation are determined, and raw materials are selected for laboratory analysis. The laboratory carries out a complete qualitative analysis of alloys and peat-sapropelic silts. The conclusion is made about the suitability of plant material for the production of fertilizers, their composition and production technology are recommended. It is important to calculate the stocks of plant and silt raw materials in the tank in order to determine the size of the treatment and processing equipment, its productivity and configuration.
Ponds are cleaned with a mini-excavator, which allows you to clean the surface of the water from vegetation, and the pond itself is cleaned of bottom sludge, removed and fed for preparation and processing. Preparation of the recovered sludge mass usually includes its ashore and dewatering, drying to the required moisture content, feeding the mass for processing and subsequent packaging with packaging of the finished product as fertilizer for agriculture.
During the operation of the mini dredger, the method of hydromechanical loosening of bottom sediments (as well as the surface plant layer of the reservoir to be cleaned) was used, and the resulting mixture was further transported to a distance of 150 m from the dredger. The transportation distance depends on the weight of the mixture being raised, the height of the lift and the speed of its movement along the flexible pipe. The consistency of cellulose created by the mixture should ensure its free movement along the entire length of the pipeline. On the frame (with platform support) from mini-equipment, one gasoline pump motor (Champion, capacity Q = 1800 l / min) and a hydraulic pump of the station (Lifan, capacity 22 l / min) with control panel mounted for a screw drive. The operation of the pump consists in removing from the bottom of the mixture, consisting of diffuse bottom sediments and small particles of the vegetable surface layer, with its delivery to the shore. A mini-excavator in a pond moves using a movement mechanism. Dredging is carried out in accordance with the readings of the lag depth gauge.
In the mini-set, geotubes can be offered. In geotubes, the recovered mixture from the reservoir is dehydrated and stored until it is used for processing.
The alloy and bottom sludge are treated after drying the raw material to a certain moisture content. To do this, use a natural climate factor or dryer. The processing equipment consists of crushers from coarse to fine fractions, dispersing mills and filling and packaging equipment. In addition, the resulting bulk fertilizers can then be encapsulated or tableted. For this, a roller press is used after grinding the dispersant. In addition, as a binder component of tabletting or pressing, you can use an organic pond with bottom sludge - sapropel.
The productivity of mining equipment is determined by the capabilities of a mini-excavator, the productivity of the processing complex is up to 20 m3 / cm.
Time parameters for putting the complex into operation: preparation of a feasibility study - not more than 1.3 months; manufacturing and supply of equipment - 3 months; installation and commissioning - 1 month;
The products meet the requirements of GOST. Packing of loose fertilizers - in bags of 10-50 liters, granular and encapsulated - in soft containers of 500-2000 liters.
