example 1

[0101] Example 1: The first bid section of the Special Project for Agricultural Non-point Source Pollution Control in the Yangtze River Economic Belt in Qingshen County is to conduct point-to-household treatment of scattered suburban and rural domestic gray water to remove pollutants so that they can be naturally scattered and discharged, irrigated farmland, and reduce pollution. For the purpose of polluting the environment and soil, the treatment system has 5-10m 3 / d Build brick-concrete structure pool and 0.5~2m 3 / d Finished FRP pool; of which 0.5~2m 3 / d Accounting for most of the construction of this project is the control project of this tender section, with a contract value of about 21 million yuan.

example 2

[0102] Example 2: Qingshen County Human Settlement Environment Improvement Project - Rural Domestic Sewage Treatment Project aims at point-to-household treatment of rural domestic sewage, removes pollutants and discharges up to standard, irrigates farmland, reduces environmental pollution, and designs and constructs 0.5m2 3 ∕d~50m 3 ∕ d Rural comprehensive gray water treatment project, in which the treatment capacity is 0.5m 3 / d~2m 3 / d There are a total of 5,300 sets of FRP finished pools, with a contract value of 187 million yuan.

[0103] During the construction of the above-mentioned projects, Sichuan Luhang Construction Engineering Co., Ltd. aimed at the small 0.5m 3 / d~2m 3 According to the situation of sewage treatment capacity, the construction method of environmental protection treatment facilities for domestic gray water of individual courtyard type is proposed systematically. By sorting out all links in the whole process of project implementation, the construct...

Abstract

The invention discloses a construction method of a retail household courtyard type domestic grey water environment-friendly treatment facility. The method is suitable for small household grey water treatment (0.5 m < 3 > / d-2m < 3 > / d) of individual household courtyards in suburbs, villages and the like; the courtyard type domestic grey water environment-friendly treatment facility has the following characteristics: (1) the anaerobic tank, the constructed wetland, the filter tank and the like are arranged in the customized glass fiber reinforced plastic cylinder body, and organic matters and suspended matters in the domestic grey water are effectively removed through the load action of anaerobic hydrolysis, microorganisms, plants and filter series, so that up-to-standard discharge of sewage is realized; the green ecological environment-friendly concept is met. And (2) compared with the traditional scheme, the courtyard type domestic grey water environment-friendly treatment facility has the advantages of dispersed construction, small occupied area, immediate use after construction, safe and reliable quality, low engineering cost and operation and maintenance cost, good treatment effect and the like. And (3) the construction method has the advantages of low mechanical and labor consumption, simple and clear construction process, easiness in adjustment of process parameters, quickness and convenience in construction, low safety risk, easiness in quality control and the like.

Description

technical field [0001] The invention relates to the field related to the environmental protection treatment of domestic gray water, and specifically relates to a construction method of an environmental protection treatment facility for domestic gray water in a courtyard type of retail households. Background technique [0002] With the improvement of farmers' living standards, the rural ecological environment has been greatly impacted. Due to historical traditions, natural geographical conditions and other factors, the scattered distribution of villages in my country has formed. A large amount of rural domestic sewage has not been collected and treated, and is discharged randomly, which seriously pollutes the rural ecological environment, threatens the health and safety of the people, and restricts rural development. At present, local standards specific to rural domestic sewage have also been promulgated, requiring different treatment methods to promote rural sewage treatment...
