Embodiment Construction

[0034] The present invention will be described in detail below in conjunction with the accompanying drawings, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Apparently, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0035] The invention provides an underground domestic sewage treatment system; the operation of the sewage treatment station adopts automatic control operation. The remote control interface is reserved to realize the remote monitoring of the operation of the sewage treatment station by the central monitoring station. The central control station can be connected with the industrial control system and the management network system of each sewage treatm...

Abstract

The invention discloses a buried domestic sewage treatment system, comprising a grille regulating reservoir, a biological contact oxidation pond, a coagulation reaction pool, a settling pond, a sludge thickener, a sterilizing device, a draught fan and liquid level control equipment. The sewage enters a digestion tank, large particles, settleable solid and floating dregs are intercepted, effluent enters the grille regulating reservoir, and is lifted to the biological contact oxidation pond by a sewage pump, the pre-treated sludge is subjected to aerobic biological treatment through the biological contact oxidation pond, an organic matter is degraded into carbon dioxide and water under the action of oxygenic aeration and a biological membrane, the effluent enters the settling pond to be subjected to mud-water separation, then the processed water is discharged, the sludge is lifted to a sludge-tank by a slime pump, and the sludge is outwards transported after being concentrated while the supernate is returned to the regulating reservoir to retreat.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to an underground domestic sewage treatment system. Background technique [0002] At present, the treatment of domestic sewage is mostly by biochemical treatment or chemical treatment. Biological treatment such as A / O anaerobic-aerobic (activated sludge) process, biological turntable and oxidation ditch process, etc., although the above treatment processes have certain effects , but because the water quality, water quantity, production process and comprehensive applicability of wastewater treatment technology are not comprehensively measured, most treatment facilities have unstable treatment effects and high operating costs. [0003] In recent years, with the further deepening of the research and application of sewage treatment technology, a broad and optimistic space has been opened up for the development of domestic sewage treatment, and a wonderful blueprint has been drawn for the...
