Abstract

The invention discloses a flocculant for urban sewage treatment. The flocculant is prepared from the following raw materials in parts by weight: 2-3 parts of polycarbonate, 2-4 parts of aluminum sulfate, 5-9 parts of aluminum chloride, 4-8 parts of iron sulfate, 4-6 parts of ferric chloride, 8-10 parts of inorganic silicate, 2-4 parts of inorganic phosphate, 3-5 parts of activated carbon, 50-70 parts of bentonite, 3-5 parts of zinc oxide, 8-10 parts of ethanol and 20-24 parts of distilled water. The proportion of the components is strictly controlled, the formula of a traditional flocculant ischanged, the source of bentonite is wide, and the component of activated carbon is added, so that a certain adsorption and purification effect is achieved; during flocculation, flocs are larger, mud-water separation is facilitated, water after treatment is clear, and flocculation effect is good. Water temperature is easily controlled by water bath heating, the preparation temperature environmentis ensured, and performance of the flocculant is more stable.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a flocculant for urban sewage treatment and a manufacturing method thereof. Background technique [0002] my country is a country seriously short of fresh water resources. With the rapid economic development and the further acceleration of urbanization since the reform and opening up, the contradiction between supply and demand of urban water resources has become more prominent. Among the nearly 700 cities in my country, more than 400 are short of water, and nearly 100 of them are seriously short of water. In order to solve the contradiction of water resource shortage, it is necessary to adopt a sustainable water resource utilization mode—conservation mode. In addition to promoting water conservation and opening up new water sources, the recycling of sewage and wastewater is also an important way. Domestic sewage is used as a water source, and after proper treatment, i...
