Ultra-micro powder sewage treatment device and sewage treatment method of sewage treatment device

Abstract

The invention discloses an ultra-micro powder sewage treatment device and a sewage treatment method of the sewage treatment device, and relates to the field of environmental protection. The ultra-micro powder sewage treatment device comprises the following processing steps: sanitary sewage taking, grid treatment, temperature adjustment of sewage, hypoxia treatment, anaerobic treatment, aerobic treatment, sedimentation treatment, treatment by an unpowered water purification treatment device, and clean water discharge. The ultra-micro powder sewage treatment device and the sewage treatment method have the beneficial effects that 1, temperature control equipment is arranged, so that the problems that the sewage is relatively low in temperature in a cold season, and is difficult to process and transport are solved; 2, a power supply adopts a convertible system of 220V / 380V, and the operation cost is also greatly reduced; 3, a denitrification process is identified; and 4, an unpowered water purification device is adopted, so that energy consumption is saved, 500-1,000t of sewage can be processed every day, an all-buried mode can be adopted in installation, a machine room can be finished into a landscape on the ground, soil resources can be saved, the environment is beautified, and the sewage treatment device is stable in operation, and low in operation and maintenance costs, has relatively efficient nitrogen and phosphorus removal ability, and is high in sewage discharge standard, which reaches the first grade A.

Description

1. Technical field [0001] The invention relates to the field of environmental protection, in particular to an ultra-micro dynamic sewage treatment device and a sewage treatment method thereof. 2. Background technology [0002] The "micro-power" sewage treatment device currently operating in my country's environmental protection industry is combined with the special conditions of the Qinghai area's topography and severe cold seasons. There are still many deficiencies, specifically high altitude, low air pressure, long cold winter, and thick permafrost. Especially in rural areas, the investment in environmental protection is high and the operating costs are high, which brings many difficulties to the normal operation of sewage stations. Secondly, the conventional domestic sewage treatment device generally adopts the activated sludge process or the A / A / O process, which has the advantage of being able to remove phosphorus and nitrogen, and the anaerobic tank is in front, and ...

AI Technical Summary

Problems solved by technology

It is beneficial to inhibit the growth of filamentous bacteria, the sludge is easy to settle, the sludge is not easy to expand, the phosphorus content of the activated sludge is high, and the sludge fertilizer efficiency is good, but there are still many problems. Although it can remove phosphorus and nitrogen, it cannot be taken into account at the same time. , the denitrification effect is affected by the reflux ratio of the mixed liquid, and the phosphorus removal effect is affected by the dissolved oxygen and nitrate nitrogen entrained in the reflux sludge, so the denitrification and phosphorus removal effect is not ideal, and phosphorus removal and dephosphorization cannot be achieved at the same time. nitrogen effect
