Abstract
The invention discloses a small buried sewage treatment device. The actual situations of the small buried sewage treatment device in engineering design and engineering application are briefly described, and the main measure is to collect the outlet water of septic tanks in all mining areas into the small buried sewage treatment device so as to further remove organic pollutants in sewage and effectively reduce the concentration of each of water quality pollution indexes including BOD5 (biochemical oxygen demand 5), CODCr (chemical oxygen demand), NH4-N, P and the like.
Description
Technical field:
The invention belongs to the waste disposal plant field, be specifically related to a kind of small-sized buried waste disposal plant.
Background technology:
Small Sewage Treatment Equipment is a kind of sewage treatment facility that occurs at home the latter stage eighties.Because of its main body structures can be embedded in usually underground or semi-underground, so be commonly called as buried.This kind device mainly is applicable to small-scale sewage and the similarly processing of organic industrial sewage with it.The main processing means that adopted at present are comparatively sophisticated bio-contact oxidation technology---be mainly A/O technology.Through rig-site utilization in recent years, small-sized buried waste disposal plant can make the sewage in outlying mining area be effectively addressed, and surrounding enviroment obtain Reasonable Protection, has promoted improving constantly of people's environmental consciousnesses.
Set up the benefit of Small Sewage Treatment Equipment: (1) is suitable for non-urbanized area protection and improves local environment; (2) be applicable to the individual curing of newly-built community life sewage in the city; (3) individual curing of the extraordinary sewage in city (like hospital wastewater); (4) as the interim control measures in some development area; (5) be the prerequisite of carrying out intermediate water reuse system under the present condition.
The invention discloses a kind of small-sized buried waste disposal plant; Small-sized buried waste disposal plant practical situation in engineering design and practical applications have been sketched; Analyze its relative merits, proposed to select according to the engineering practical situation suggestion of waste disposal plant.
Summary of the invention:
The objective of the invention is to disclose a kind of small-sized buried waste disposal plant; Small-sized buried waste disposal plant practical situation in engineering design and practical applications have been sketched; Main behave is that the septic tank effluent with each mining area is collected into small-sized buried waste disposal plant; Organic pollutant in the sewage is further removed, effectively reduced BOD

Sewage water inlet pipe 1 among Fig. 1, grid 2, oxygen-starved area 3, aeration zone 4, settling region 5, fan house 6, discharging pond 7.
Embodiment:
In conjunction with Fig. 1, the present invention is further described through embodiment.
A kind of small-sized buried waste disposal plant is characterized in that mainly being made up of totally 4 unit oxygen-starved area 3, aeration zone 4, settling region 5 and fan house 6, and its order of connection is followed successively by: oxygen-starved area 3, aeration zone 4, settling region 5 and fan house 6.
Get into oxygen-starved area 3, microbial culture through grid 2 preliminary filtering sewages.Seed sludge is taken from the municipal sewage plant, presses the high loading continuous culture method and cultivates.By getting sewage water filling in device in the septic tank, after filling with, sewage stops into water, vexed 3 d that expose to the sun with interim submersible sewage pump.Intake continuously and aeration by the design flooding quantity subsequently, after the mud flco appears in the aeration zone, start the inner circulating reflux pump.About 30 d of microbial culture time, the settling property of active sludge is good, many protozoons occurred, is main with nematode, campanularian and a spot of amoeba wherein, and the microbial culture success is described.Device water outlet BOD
