Water quality stabilization bricks

The invention relates to water quality stabilization bricks, which comprise a meshed shell, high polymer porous medium carriers, porous media carriers with large specific gravity and flukes, wherein the high polymer porous medium carriers and the porous medium carriers are arranged on upper and lower parts in the meshed shell respectively; at least two flukes are arranged at the bottom end of themeshed shell; the high polymer porous medium carriers are made of polyurethane blasting foaming fillers with a specific gravity of less than 1; and the porous medium carriers are made of volcanic, zeolite or porous baked bricks. The water quality stabilization bricks have the advantage that high polymer porous media are taken as the carriers to generate a large number of anaerobic bacteria and facultative bacteria epiphytically, so that an anaerobic reaction zone is formed in specific water bodies in a certain distribution way (normally at the bottom of water bodies). Microorganisms perform ametabolic reaction under t
