The invention provides an integrated
sewage treatment apparatus and a
sewage treatment process flow using the apparatus. The
sewage treatment apparatus comprises an anaerobic biological treatment
pool, an aerobic biological treatment
pool, a sewage
sedimentation pool and a membrane
biological reaction pool; and the anaerobic biological treatment pool, the aerobic biological treatment pool, the sewage
sedimentation pool and the membrane
biological reaction pool are sequentially connected. The apparatus is used to carry out effective integrated treatment on sewage. The integrated
sewage treatment apparatus has the advantages of good sealing property, strong adaption ability to various foundation conditions, acid and alkali resistance,
oxidation resistance, no deformation under high or low temperature, and long service life. The sewage
production cycle and the onsite construction installation cycle are short, so the apparatus can be fast used; early disposable investment is small, so the
operating cost is low; the quality of discharged water is stable, and
pollution discharge is maximally treated; the
sewage treatment apparatus has a small size, saves space, can be conveniently carried; and the apparatus can be used in a landfill mode, so the occupied earth's surface area is extremely small,
noise is small, and the apparatus can be extremely well combined to surrounding
living environment.
