Special Microbe Used for Filtered Sludge Treatment in Sewage Treatment Plant

Product Description:

    SKHZYE SLW-300 is a microbial product and consists of many high concentrations of beneficial non-pathogenic microorganisms and many enzymes that can degrade a variety of macromolecule substances. It is made by unique formula and contains many anaerobic, aerobic multifunctional bacteria strains. The microorganisms in this product will generate digestive enzymes in the process of growth and reproduction to degrade the large amount of organic waste in filtered sludge of municipal wastewater treatment plant. It can also remove the obnoxious odor in sludge. The decomposition products can be further transformed through oxidation, reduction and hydrolysis reaction and in the end turned into organic fertilizer.

Working Mechanism:

    Microorganisms in composts can produce large amount of heat in the process of decomposition to heat the composts. This high temperature is necessary for fast decomposition and also conducive to the destruction of the weeds seeds, insect larvae, harmful bacteria, etc. and can inhibit the breeding of certain diseases so as to avoid these diseases generating harmful microorganisms to impede normal growth of plants.

The addition of fermentation microbe strains can increase the decomposition rate and efficiency as these microbe strains are mixture of highly concentrated bacteria and fungi through screening, acclimation, cultivation and improvement. These strains are chosen for better survival and reproduction and at the same time they generate enzymes and decompose organic waste to accelerate the decomposition of organic matters in the composting process.

The standard concept of decomposing wood cellulose is to open the fiber structure firstly, so that the sugar can be used for different microbial metabolism. Microorganisms release sugar to the composts from cellulose, hemi-cellulose, protein, starch and other carbohydrates by cellulolytic enzyme, zytase, a-amylase, protease and ligninolytic enzymes. If the growth of target bacteria is strengthened in composts, it can effectively inhibit the growth of other bacteria and prevent odor, pathogenic bacteria and other harmful substances.


l        Decompose the organic waste in garbage for waste reduction;

l        Remove obnoxious odor of the sludge;

l        Through the fermentation, the filtered sludge can be used as bio-organic fertilizer of farmlands or vegetable fields.

Beneficial microorganisms in the composts:

l        Composting process is to utilize the beneficial microorganisms and higher animal life body to decompose the organic matters in industrial, urban and agricultural waste.

l        The organic matters in solid waste can also be decomposed through biological method in the process of composting. In this process, the solid organic waste will be decomposed by aerobic, mesophilic and thermophilic microorganisms.

l        The composting process is a microbial process, and it can transform the organic waste into stable, hygiene and humus-like products to improve soil composition.

l        It will promote the decomposition of organic matters through add highly concentrated beneficial bacteria strains that be screened, acclimated, cultivated and improved with better viability, faster reproductive capacity and strong enzyme-producing ability to the inherent natural microbial strains in composts.

l        The effective integration of beneficial microorganisms will greatly reduce the fermentation time of composting.
