Abstract
The invention discloses an activated sludge purifying and processing method for wastewater. The method comprises the following steps: (1) uniformly mixing and severely stirring sewage and activated sludge; (2) feeding oxygen to improve the dissolved oxygen in the wastewater uniformly at the bottom of a tank; (3) standing and settling after the completion of reaction; (4) separating out the settled active sludge; and (5) filtrating the wastewater to obtain purified water. By this way, the activated sludge purifying and processing method for wastewater provided by the invention has the advantages of obvious biotreatment effect, improved efficiency, cyclic utilization and the like, therefore the popularization of the activated sludge purifying and processing method for wastewater has an extensive market prospect.
Description
Technical field
The present invention relates to environmental protection sciemtifec and technical sphere, particularly relate to a kind of activated sludge purification treatment process for waste water.
Background technology
The energy is the basis that modern society depends on for existence and development, and the supply capacity substantial connection of the energy the sustainable development of national economy, is one of basis of national strategy safety control.The situation is tense for the current energy resource supply of China, and environmental quality burden is heavy.Due to fossil energy reserves day by day reduce, oil price volatility is comparatively large, the worry to energy security problem and the concern to Global warming, development clean reproducible energy has become urgent problem, and new forms of energy industry presents high development.
Existing natural energy resources mainly comprises water energy, wind energy, sun power, tidal energy, biomass energy etc., wherein water resources occupies most of area of the earth, one of our energy of depending on for existence, along with the progress of science and technology and the development of society, trade effluent and sanitary wastewater get more and more, but the process of waste water is but gone no further, can not effectively realize science recycle.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of activated sludge purification treatment process for waste water, adsorb the organic substance in waste water by adopting active sludge and decompose larger molecular organics, good purification, recycle, efficiency improve, and have market outlook widely popularizing of the activated sludge purification treatment process for waste water.
For solving the problems of the technologies described above, the invention provides a kind of activated sludge purification treatment process for waste water, comprising the following steps:
