Planar vertical flow (PVFL) flow state and sewage biochemical treatment key technology and complete set of engineering equipment

Abstract

The invention belongs to thetechnical field of sewage treatment, provides a planar vertical flow (PVFL) flow state and sewage biochemical treatment key technology and a complete set of engineering equipment, and in particular relates to a flow state simulation and optimization technology of sewage biochemical treatment, cultivation and screening of biological strains liking eating mud, bionic design of ultrafiltration function of molecular gills as well as an eight-trigram six-palace equipment structure and appearancestructure for realizing PVFL flow state. The invention has the characteristics that the biological strains pleasantly eat mud under an autotrophic interest-bearing environment in an anaerobic, aerobic and oxygen-enriched labyrinth; and according to the gill filtering principle, an ultrafiltration system of the molecular gills is bionically designed, so that the discharged water quality reaches, even exceeds the membrane filtration process level, the investment is greatly reduced, and the sewage treatment reaches the drinkable standard. The equipment has wide application market and good economic benefits in coal chemical industry, shale oil gas fracture (drilling), petrochemical industry, military field camp, travel motor home camp and environment-protecting sewage treatment.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and provides a key technology and a complete set of engineering equipment for vertical vertical flow (PVFL) flow state and sewage biochemical treatment. Background technique [0002] Sludge is a worldwide problem in wastewater treatment processes. The investment in sludge treatment equipment accounts for 46% to 60% of the water treatment process, but it is still unable to completely solve the problems of sludge odor, harmful and toxic chemicals, heavy metals and radioactive elements, and still cannot completely solve the problem of its discharge on the natural environment. The problem of "secondary pollution" still cannot completely solve the problem of high-value reuse of sewage treatment resources. [0003] The present invention realizes PVFL through the maze structure of the equipment according to the turbulent flow mechanism of interlaced agitation flow state PVFL of plane laminar f...
