Apparatus and process for clarifying water efficiently

Abstract

The invention is concerned with a kind of high efficiency water treatment equipment and technology belonging to water treatment field. The middle parts of the equipment are two flocculating rooms having mesh setting with disturbing flow, and the bottom of the flocculating room is precipitation tank. The suspending layer of active mud residue is out of the flocculating room and there is slanting pipe on top of it and concentrate room under it. The pipe excluding residue sets in the suspending layer of active mud residue, and the bottom of clean tank is filler to exclude residue, and there is siphon pipe connecting with the filler. There are grooves excluding residue at top of the flocculating room connecting with the pipe excluding residue and the siphon pipe connects with the residue reuse tank. The filler to exclude residue connects with a pump of reused residue. The equipment gathers the small air flotation, flocculating, active mud residue layer flocculating, and reused technology. Compared with traditional mixed and coagulate deposition technology, it saves 40 percent of field, reduces 10 percent of drug and enhances 15 percent disposal efficiency.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to an equipment and process for water supply treatment, sewage treatment, reclaimed water reuse treatment or water quality purification treatment, in particular to a high-efficiency clarified water treatment device and process. Background technique [0002] With the rapid development of social economy and the continuous improvement of people's living standards, water consumption in urban and rural areas has gradually increased. However, due to the massive discharge of industrial and agricultural wastewater, water pollution has become increasingly serious. In response to the above situation, various water quality standards formulated by various countries are becoming increasingly strict. [0003] Clarification tanks that use the principle of contact flocculation to remove suspended solids in water began to be used in the world as early as the 1930s, and have beco...
