Buried type glass fiber reinforced plastic integrated sewage treatment equipment and process

Abstract

The invention belongs to the technical field of sewage treatment and in particular relates to buried type glass fiber reinforced plastic integrated sewage treatment equipment and process. The buried type glass fiber reinforced plastic integrated sewage treatment equipment provided by the invention is wholly buried into the ground and comprises a grid tank, a regulation tank, a hydrolysis-acidification tank, an MBBR (Moving Bed Biofilm Reactor) tank, an inclined tube sedimentation tank, an intermediate water tank and a clean water tank, wherein the grid tank, the regulation tank, the hydrolysis-acidification tank, the MBBR tank, the inclined tube sedimentation tank, the intermediate water tank and the clean water tank are sequentially arranged in series. According to the buried type glass fiber reinforced plastic integrated sewage treatment equipment provided by the invention, the sewage treatment amount reaches 10m<3> / d to 200m<3> / d; sewage is treated for 24h and a designed treatment water amount is 0.5m<3> / h to 10m<3> / h; the treatment capacity per year reaches a grade of ten thousand tons or more; the buried type glass fiber reinforced plastic integrated sewage treatment equipment has the advantages of simplicity in operation, reasonable structure, high treatment efficiency, low investment cost and low operation cost.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a ground-buried FRP integrated sewage treatment equipment and process. Background technique [0002] With the growth of economy and population, the pollution of nature has been paid more and more attention by human beings. Water, as an irreplaceable resource needed by human beings, is one of the important pillars for the sustainable development of society. The survival and development of human beings not only consume huge amounts of water resources, but also discharge a large amount of pollutants into the environment, causing obvious deterioration of the environment. In order to protect the water ecological environment and benefit future generations, not only the sewage generated in production and life should be treated, but also reused to save water resources. [0003] In the traditional rural areas of China, there is a prominent contradiction of "there is...

AI Technical Summary

Problems solved by technology

There are no sewers and drainage systems in rural areas, and there are no collection facilities. The scattered geographical distribution of villages makes sewage scattered and difficult to collect.

[0006] (2) Many sources

[0008] (4) Low processing rate

There are no collection facilities in the countryside, and these waters are dispersed. With the erosion of rainwater, surface water flows into rivers, lakes, ditches, ponds, reservoirs and other water bodies, soil water and groundwater bodies, causing water pollution.

[0009] (5) Northeast China is cold in winter, and the temperature drops below -20°C, and the soil layer will freeze to about 1.5 to 2 meters, which brings difficulties to the treatment

[0013] (2) There are many pollution points, the amount of sewage at a single point is small and the location is independent, and the amount of sewage fluctuates greatly over time

[0015] (4) The uneven coefficient of sewage is large, and the hydraulic impact load is large

[0016] (5) In the early expressway service areas, septic tanks were mainly built for simple treatment of sewage, but the treatment effect of septic tanks was not very satisfactory, and the quality of the treated water was unstable and easily caused groundwater pollution

[0017] For the domestic sewage in rural villages and towns and expressway service areas in my country are generally far away from the city and cannot be directly incorporated into the municipal sewage pipe network of the city, it is necessary to develop a sewage treatment equipment system with a reasonable structure and low operating costs. The sewage treated is generally made of feces Composition of sewage and catering washing water

At present, there are many mature domestic sewage treatment processes in China, and more biochemical processes are: anoxic-aerobic activated sludge process (A / O) process, anaerobic-anoxic-aerobic activated sludge process ( A / A / O) process, MBR membrane biological reaction process, biological aerated filter (BAF) process and intermittent, etc., but due to the general solubility of CODcr and BOD5 indicators of domestic sewage in rural towns and sewage in expressway service areas are relatively high , BOD:COD ratio > 0.3, need to develop new treatment methods
