Unpowered biochemical pretreatment device with water quality and water quantity regulation function

Abstract

The invention provides an unpowered biochemical pretreatment device with a water quality and water quantity regulation function. The device consists of a grille, a water inlet flow guide pipe, an anaerobic/hydrolytic acidification water quality regulation pretreatment area, a water quantity regulation area, a water outlet pipeline maintenance safety valve, a filter, a water discharge flow large regulation valve, a water discharge flow micro regulation valve and a water outlet pipeline, wherein a biological filling material is arranged in the water quality regulation pretreatment area; a water outlet hole (pipe) is formed in (arranged on) a partition wall at the upper part of the filling material. The device provided by the invention makes full use of the advantages of an anaerobic/hydrolytic acidification biological treatment process, reserves the water quantity regulation area, controls the water discharge flow by adopting the combination of the water discharge flow large regulation valve and the water discharge flow micro regulation valve, ensures that the whole device integrates all the functions of the grille, an anaerobic/hydrolytic acidification biochemical pretreatment tank and a regulation tank, is less in floor area of equipment, simple in structure and simple and convenient in operation, does not need energy consumption when in operation, and is a practical and feasible process aiming at the pretreatment of small and distributed domestic sewage such as rural sewage and the like.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment and resource utilization, and is especially suitable for small-scale and distributed domestic sewage pretreatment such as village and town sewage. Background technique [0002] Since the beginning of the 21st century, with the advancement of rural reform and the support of national policies, the rural economy has developed rapidly and the living standards of farmers have greatly improved. However, with the improvement of rural production and farmers' living standards, the rural ecological environment is seriously polluted, and the living environment is deteriorating day by day. [0003] The problem of rural environmental pollution is mainly reflected in two aspects: domestic waste pollution and domestic sewage pollution. Among them, domestic waste is given a higher degree of attention. Most villages have used the urban domestic waste treatment model to clear, transport and fill the domest...

AI Technical Summary

Problems solved by technology

The effluent water quality of the treatment system without adjustment function is greatly affected by the influent water quality and water volume. In addition to the deterioration of the effluent water quality, it is also reflected in the impact on the main treatment unit, especially the biochemical treatment unit, which destroys the biochemical system. Stability; with the adjustment function, it often means that a sewage lift pump is required, which will continue to generate energy consumption
