Embodiment 1

[0028] Up to standard septic tank. Its main structures include a septic tank 2 and a biological contact oxidation filtration sedimentation tank 3; a channel I3 is set between the septic tank 2 and the biological contact oxidation filtration sedimentation tank, and a grid 4-2 is set on the side of the channel I3 near the septic tank 2; After being treated in the slag tank 2, the sewage enters the biological contact oxidation filtration sedimentation tank 3 from the channel I4, in which large solid pollutants are intercepted in the septic tank 2, and the sewage is filtered, precipitated and biochemically processed in the biological contact oxidation filtration sedimentation tank 3. Function to remove pollutants and increase dissolved oxygen in effluent.

[0029] The present invention comprises the following steps when reaching the lower effluent standard requirements:

[0030] (1) Sediment: Sewage enters the slag tank 2 through the water inlet pipe, settles in the slag tank 2 a...

Embodiment 2

[0035] Grade A septic tank. Its main structures include septic tank 2 and bio-contact oxidation filtration sedimentation tank 3; channel I4 is set between septic tank 2 and biological contact oxidation filtration sedimentation tank, and grille 4-2 is set on the side of channel I4 close to septic tank 2; sewage After being treated in the slag tank 2, it enters the biological contact oxidation filtration sedimentation tank 3 from channel I4, in which large solid pollutants are intercepted in the septic tank 2 for sedimentation or floated up for removal, and the sewage is filtered and precipitated in the biological contact oxidation filtration sedimentation tank 3 and biochemical action to remove pollutants and increase dissolved oxygen in effluent.

[0036] An aeration system 5 is provided in the biological contact oxidation filtration sedimentation tank 3 to increase the dissolved oxygen content to cause aerobic biochemical reaction to degrade pollutants in the domestic sewage ...

Abstract

The invention discloses an up-to-standard septic tank and aims to integrate pretreatment and deep treatment of living sewage. The up-to-standard septic tank mainly comprises a manure sludge tank, a tubular grid, an indirect backflow system and a biological contact oxidation filtering settling pond. Sewage is subjected to filtration, settling and biochemical action in the up-to-standard septic tank, pollutants are removed, the water dissolved oxygen is increased, and the sewage is directly discharged or recycled after corresponding standards are met. The investment and operation cost of the up-to-standard septic tank is increased to a certain extent when being compared with that of a conventional septic tank, but a conventional sewage treatment mode of 'septic tank+sewage collection pipeline net+concentrated sewage treatment' is changed, the investment of pipeline nets and sewage treatment plants is reduced, and sewage can be recycled on site conveniently.

Description

technical field [0001] The invention belongs to the field of water pollution control and sewage treatment, in particular to a septic tank that meets the standard of direct discharge or reuse. Background technique [0002] The septic tank is an important domestic sewage pretreatment device, but the pure use of septic tanks to treat domestic sewage cannot meet the relevant standards for direct discharge or reuse, and can only be discharged or reused after advanced treatment. However, the investment and operating costs of the scattered domestic sewage advanced treatment facilities are high, so the sewage collection pipe network is built to collect the scattered sewage and then a centralized sewage treatment plant is built for advanced treatment. This is the domestic sewage treatment mode of "septic tank + sewage collection pipe network + centralized sewage treatment plant" widely used at present. [0003] The investment and operation costs of the existing domestic sewage treat...
