Domestic wastewater treating agent

Abstract

The invention discloses a domestic wastewater treating agent. The 1L of treating agent contains 10-20g of polyaluminum chloride, 1-8g of ferric chloride, 10-20g of polyvinyl alcohol and the rest of water. Suspended matters, oils and colored substances in domestic wastewater can be effectively removed by adopting the domestic wastewater treating agent for treating domestic high-quality miscellaneous wastewater. The domestic wastewater treating agent has good effect and higher treatment efficiency. Treated reclaimed water can meet the requirement of water quality standard of domestic miscellaneous water and can be used for watering flowers, flushing toilets and the like. The domestic wastewater treating agent has the advantages of being capable of increasing the utilization ratio of the domestic reclaimed water, being beneficial to the harmonious development of human and nature, creating a good water environment, easing the gradually serious environment pollution and promoting the development process of recycling cities.

Description

technical field [0001] The invention relates to a wastewater treatment agent, in particular to a domestic wastewater treatment agent. Background technique [0002] The water after the deep purification of the urban sewage treatment facilities (including the water after the secondary treatment in the sewage treatment plant and the water after the in-depth treatment, and the water after the centralized treatment of large buildings and living communities, such as bathing water and vegetable washing water) are collectively referred to as "Medium water". Its water quality is between tap water (upper water) and sewage (lower water) discharged into the pipeline, so it is called "reclaimed water". In the United States, Japan, Israel and other countries, a large amount of reclaimed water is used for toilet flushing, garden and farmland irrigation, road cleaning, car washing, urban fountains, and supplementary water for cooling equipment. my country is a water-poor country, and the ...

AI Technical Summary

Problems solved by technology

The composition of household wastewater is generally relatively stable, but it is very complicated. If it is used directly without treatment, there will be problems such as odor, color, and oil film.

my country's existing residential quarters basically have no relevant reclaimed water reuse facilities, and it is impossible to realize reclaimed water reuse at the community level

If the community is remodeled in units of the community, the cost of the renovation is high and the construction is very difficult

Therefore, household water reuse devices should be promoted, but large-scale treatment equipment cannot be used in households due to site and space constraints

The existing domestic wastewater treatment methods are mainly sedimentation, filtration, etc., which cannot effectively remove suspended solids, grease and colored substances in household wastewater
