Abstract

The invention discloses an environment friendly wastewater treatment system having the advantages of high efficiency and low energy consumption. The wastewater treatment system comprises a primary sedimentation tank, an aeration tank, an aerobic biological treatment tank, a bioreactor, an activated carbon treatment unit, an electric water pump, an aerobic sludge reflux tanks, a reflux unit for an oil-water separation tank and a PLC (programmable logic controller) automatic control system, wherein the aerobic biological treatment tank is adjacent to the first anaerobic sludge reflux tank and connected with the first anaerobic sludge reflux tank; the center of each overflow weir with the edge thereof being zigzag-shaped is connected with the aerobic biological treatment tank and the aeration tank; a water-separation tank pipe and the reflux unit for the oil-water separation tank are used for treating the sludge and clearing the water; the separation tanks are adjacent and connected with the aerobic biological treatment tank and the aeration tank which are respectively in controlling connection with pipes; releasing water tanks are adjacent and connected to each other; a generating tank and a separating tank are adjacent, connected to each other, provided with a sludge reflux opening, and connected with the bottom of the aerobic biological treatment tank via water pipes; and a sewage draining hole and the releasing water tanks are arranged between water pipes provided with a control valve.

Description

A kind of environmental protection, high-efficiency wastewater treatment system

One, technical field

The present invention relates to a kind of environmental protection, high-efficiency wastewater treatment system.

Two, background technology

At present, Sewage treatment systems have that efficient is low, energy consumption greatly, the problem of not environmental protection.

Three, summary of the invention

The object of the present invention is to provide a kind of environmental protection, the high-efficiency wastewater treatment system that overcome above shortcoming, be provided with primary clarifier, aeration tank, aerobe treating pond, bio-reactor, activated carbon treatment device, electric water pump, anaerobic sludge return tank, oil-water separation tank reflux, PLC automatic control system; The aerobe treating pond is adjacent with first anaerobic sludge return tank, interconnect, the center of each overflow weir provide with above-mentioned overflow weir limit be meander-like, connect aerobic biological treatment tank and aeration tank; Handle mud, and clarification, water separation tank pipe, oil-water separation tank reflux; Above-mentioned separator tank is adjacent, connect aerobic biological treatment tank and aeration tank respectively with the pipeline control linkage; Above-mentioned release water tank is adjacent, interconnects; Generation tank and separating tank are adjacent, interconnect, and provide the mud reflux opening at it, and are connected both at the bottom of the aerobe treating pond and are connected by waterpipe respectively; One has and above-mentioned sewage draining exit is provided between the control valve water pipe and discharges water tank; The deep layer sewage disposal device of no mud discharging on request, the settling tank trash rack, with in and primary clarifier, the aeration tank, aerobe treating pond and anaerobic pond and mud reflux, mud and primary water separating tank, separator tank; Be to integrate anaerobism, aerobic, take upflow type anaerobic filter tank, the multistage circular flow of downflow system anaerobic filter, in conjunction with bio-contact oxidation, precipitation, disinfectant method, the most of organism in the sewage relies on multistage circulation section anaerobic digestion.

Bio-reactor is used to handle the algae of quick growth, and the extraction means that can also be used reliably and are effectively eliminated the oil that produces these algae and alga cells, promote the recirculation of nutrient, and allow more algal grown to react.

The gac (BAC) that is used for water treatment, owing to have huge specific surface area and flourishing pore texture, pollutent in not only can planar water, can also become the desirable habitat of microorganism in the water, under suitable temperature and nutritional condition, use it for water treatment, can bring into play the dual function of gac physical adsorption and microorganism biological degraded simultaneously.

Transmitter through A/D conversion input PLC controller, is realized automatically operation through time variable control with the correlation parameter signal; PLC system CPU module is connected by serial line interface with display screen, and Sensor Analog Relay System amount load module is connected by the I/O mouth, according to artificial judgment schedule of operation establishment PLC program.
