Embodiment Construction
[0026] Such as figure 1 , 2 Shown: 1 is a small unit body, the shape of the small unit body 1 is spherical, and its diameter is determined between 20-60 millimeters, that is, 20 millimeters, 30 millimeters, 40 millimeters, 50 millimeters or 60 millimeters, or different Regular approximate spherical, or polyhedral shape. Pores can be formed inside the small unit body 1, and the porosity is about 30-50%. The carrier biochemical ball 3 is bonded to each other by the above-mentioned several small unit bodies 1 (see figure 2 ) or several small unit bodies 1 are covered with a mesh cover 2 (see figure 1 )Forming. Wherein the net cover 2 can be made of materials such as plastic or stainless steel, and the two split-type hemispherical shells can be buckled and connected into a spherical shape. The diameter of carrier biochemical ball 3 is controlled at 200 mm or 300 mm or 400 mm or 500 mm or 600 mm, as long as it is between 200 mm-600 mm.

Abstract
Provided are carrier biochemistry balls and a biological purification bed which are used in biologic purification and treatment of water bodies. The carrier biochemistry ball comprises a plurality of small unit bodies which are integrally connected to form a carrier biochemistry ball, and gaps are left among a plurality of small unit bodies which are arranged inside the carrier biochemistry ball.The biological purification bed comprises a biological purification bed body. One end of the biological purification bed body is provided with water inlets, and the other end of the biological purification bed body is provided with water outlets. The biological purification bed is internally provided with pluralities of the carrier biochemistry balls. The spherical structure of the carrier biochemistry balls is provided with comparatively high specific surface area (the ratio of water contact area and surface area of sphere), as the water contact area under the water is large, large-area space is provided for microorganisms, and positive effect for the microorganisms to disintegrate organic matters from the water is achieved.
Description
technical field [0001] The invention relates to a water treatment carrier and facilities, in particular to a carrier biochemical ball and a biological purification bed for biological purification treatment of slightly polluted water, which are mainly used for biological purification treatment of slightly polluted water. Background technique [0002] At present, there are many regions and cities lacking fresh water resources, which has gradually become the main problem that plagues the development of relevant regions and cities. In recent years, most cities have required that landscape water bodies must use recycled water as a supplementary water source. Measured according to relevant standards, compared with surface water, the water quality of recycled water belongs to eutrophic water quality. After this water quality is replenished according to the current corresponding national standard requirements, the water body can only be kept for five days, otherwise it will cause eu...
