Problems solved by technology

[0003] In view of the fact that most of the existing water purifiers are made of chemicals, or use inorganic acids, alkalis or chlorides to purify water, although such water purifiers can eliminate and kill toxic substances in the water. Harmful substances purify the water body, but at the same time of sterilization and disinfection, its own toxic organic components remain in the water body, thereby increasing the organic components in the water body, making it diffic

[0020] Example 1

[0021] Polyferric chloride 15kg, sodium aluminate 10kg, sodium carboxymethyl starch 3kg, sodium silicate 3kg, nano-montmorillonite 60kg, activated carbon 10kg, modified starch 60kg, sugar glycosides 3kg, alum 5kg, calcium chloride 3kg;

Example Embodiment

[0022] Example 2

[0023] Polyferric chloride 20kg, sodium aluminate 15 parts kg, carboxymethyl starch sodium 4 parts kg, sodium silicate 4 kg, nano-montmorillonite 70 kg, activated carbon 15 parts kg, modified starch 70 kg, glycoside sugar 4 kg, alum 10 kg, Calcium chloride 4kg;

[0024] The method for preparing the above-mentioned Examples 1 and 2:

[0025] All the raw materials in the raw materials are put into the ball mill according to the ratio, mixed by the ball mill, and ground to a fineness of 350-450 meshes, and packed separately to obtain the microbial coagulant for urban sewage.

[0026] The following table is the experimental data obtained by carrying out the sewage treatment detection of this embodiment:

[0027]

[0028]

[0029] As can be seen from the table, the present invention can effectively remove SS, COD, BOD, organic matter and grease in the sewage by using the primary physical and chemical enhanced coagulation treatment agent in Examples 1 and ...

Abstract

The invention relates to microbial coagulant for town sewage, in particular to a town sewage curing agent and belongs to the technical field of sewage treatment. The microbial coagulant comprises 15-25 parts of polymerization ferric chloride, 10-20 parts of sodium aluminate, 3-5 parts of sodium carboxymethyl starch, 3-5 parts of sodium silicate, 60-80 parts of nano-montmorillonite, 10-20 parts of activated carbon, 60-80 parts of modified starch, 3-5 parts of glucoside, 5-15 parts of alum and 3-5 parts of calcium chloride. The town sewage curing agent has the advantages that the technical process is simple, the raw material ratio is reasonable, raw materials are cheap and available, all the raw materials play a synergistic role, various metal ions in water can be captured, meanwhile a significant corrosion and scale inhibition function is realized, scaling and corrosion of the system can be reduced effectively, production cost is lowered, suspended matters flocculate immediately and settle fast after the agent is added into sewage, and suspended matter removal rate can reach above 90%; the treated sewage is up to emission standard, floc strength is high, and hydrophobic nature is good.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an urban wastewater solidification and elimination agent and a preparation method thereof. Background technique [0002] In recent years, the number and population of cities and towns in our country have grown rapidly. Due to the lagging development of environmental planning and environmental protection in many central towns or small market towns, the phenomenon of water pollution and eutrophication in surrounding areas has become increasingly prominent. Small towns in many areas discharge untreated sewage arbitrarily, which not only pollutes large areas of water, but also reduces the use value of water. Due to the scattered discharge points of sewage in small towns, it is difficult to centralize treatment, so the combination of centralized treatment and decentralized treatment is mainly adopted. In addition, due to economic reasons, small towns can only adopt technolog...
