Abstract: The present invention discloses a treatment process for a submerged lifting circulation type bio-membrane filter, wherein the treatment process comprises the following steps: two groups of symmetrically staggered filter curtains (2A and 2B) are adopted; the two groups of filter curtains (2A and 2B) are periodically lifted up and down in a reciprocating manner in a biofilter (1) under the action of a lifting mechanism (4), so that bio-membranes on the two groups of filter curtains (2A and 2B) are in contact with the atmosphere and sewage in turns, absorb organic matters in the sewage when lifting down for submerging, absorb oxygen when lifting up and exposing into to the atmosphere, and bring oxygen into the sewage and cause sewage turbulence in a water tank when lifting down for submerging again, so that the dissolved oxygen is uniformly distributed, thereby purifying the sewage.

Abstract: A crawler-type automatic vending machine includes a replenishment unit, m transfer units, n container units, a detection and control unit, a cloud management platform and a payment system. The replenishment unit, the transfer units and the container units are connected successively to form an integral crawler-type automatic vending machine, wherein m and n are natural numbers other than 0; when n is equal to 1, m is equal 1; when n is greater than 1, m is equal to n+1; and when n is greater than 1 and m is equal to n+1, the m transfer units and the n container units are connected alternately, and the last unit is the transfer unit. When n is equal to 1 and m is equal 1, the transfer units and the container units are made into an integral structure.
